International Pulp Week kicked off today at the Pan Pacific Hotel in Vancouver, BC. This annual three-day conference organized by the Pulp and Paper Products Council brings together the world’s leading producers of market pulp, suppliers, financial analysts, logistic companies, and their customers for a first-class informational and networking opportunity. The goal of the event is to provide knowledge, data, and in-depth analysis on the latest market developments and trends in the market pulp industry worldwide as well as to serve the market pulp industry by allowing for a multitude of business meetings and networking opportunities that would otherwise require travel to several continents. Stay tuned all week for Tree Frog News coverage of the event. Here are a few of the attendees gathered at the opening reception.
British Columbia is world renowned for its incredible wilderness landscape, mountains, rivers, lakes and forests. It’s a great place to live, work and play. Our forests are regionally diverse – from coastal and interior rainforests, dry belt pine and fir forest and higher elevation spruce and balsam, old growth and new growth – they all have one thing in common … trees! 
Whether working or playing, it is essential to be aware of a forest’s potential hazards and what can put you at risk, specifically as it relates to the trees. …“If a tree falls in the forest, does anyone hear?” … only if someone is near enough to hear. The same applies to the danger it may pose. If no one is near it, then even if it falls, it isn’t a danger to anyone. Spend enough time in a forest and you will witness a tree fall over on its own.
These weekly resources are simple yet powerful tools to help keep safety conversations alive and evolving in your workplace. BCFSC offers a library of hundreds of Crew Talks each designed to support short, focused safety discussions in five minutes or less. They support effective supervisor-worker engagement, helping spark meaningful conversations about current safety procedures and concerns.
People who work outdoors can often be at the highest risk for heat-related illnesses and injuries during hot summer conditions. High temperatures and sunshine can be a wonderful thing when enjoying time at the lake or on the beach but can cause serious health issues. The wide variety of job roles and often rigorous physical activity in forestry can put workers at risk for heat-related illness if not managed properly.
Managing psychological health and safety in the workplace is as important as managing physical health and safety. A psychologically healthy and safe workplace prevents harm to workers’ mental health and promotes mental well-being. While many factors outside the workplace can affect mental health, it is an employer’s responsibility to address the factors that are within the control, responsibility, or influence of the workplace. Psychological health and safety involves how people interact with each other daily, how working conditions and management practices are structured, and how decisions are made and communicated. In the forestry sector, workers face unique psychological challenges, including financial stress from an unstable market, job instability, social isolation, and the impact of climate change and severe weather conditions.
CHEMAINUS, BC — Fifty-five workers are scheduled to be laid off after a shortage of viable logs has forced production at the Chemainus Sawmill starting this month. According to North Cowichan mayor Rob Douglas, Western Forest Products has informed the municipality they intend to start curtailment of the jobs on Jun. 18. “The company has indicated the reason for the shutdown is due to their inability to find a viable supply of fiber,” Douglas says. “We don’t have a date as to when Western Forest Products is going to resume operations at the Chemainus Mill, but we hope it’s very short term.” …“I have reached out to the forest minister (Ravi Parmar),” he says. …Delays in permits and cutting fiber is a long-standing issue in BC, which has led to shutdowns and impacting production, but Douglas says he has been reassured by Parmar that the province is addressing the issue.
SLAVE LAKE, Alberta — On Saturday, May 24, West Fraser’s Slave Lake Veneer plant celebrated its 50th anniversary with the community of Slave Lake. Several hundred community members, elected officials, Indigenous leaders, employees and retirees joined the company for a day of festivities, including lunch, bouncy castles, face painting and an opportunity to learn more about the history of Slave Lake Veneer’s operations. These directly employ 150 local residents, mostly in the mill, but also in the woodlands department, as well hundreds of more with contractors that supply the operation. …West Fraser acquired Slave Lake Veneer in 1999, as part of its acquisition of Zeidler Forest Products. At the time, the mill operated as both a veneer plant and a stud mill. In 2016, all lumber production was transferred to the newly-acquired sawmill in High Prairie. Today, veneer output is almost 13 times higher than when the plant opened in 1973.
As Prime Minister Mark Carney’s Liberal government plans billions in financing for builders of prefabricated homes, one expert says it’s a “significant amount of money” and “a very healthy kick-start” for the industry. The federal government’s Build Canada Homes (BCH) plan promises, among other things, more than $25 billion in financing to “innovative prefabricated home builders in Canada,” according to the Liberals’ website. Ramping up prefabrication could result in cheaper, faster and better-quality homes, said Tony Yang, professor of structural and earthquake engineering at University of British Columbia. “We are building too slowly right now,” he said. “We are lacking skilled workers on site.” The goal of prefab is to shift manufacturing from construction sites, which he called relatively inefficient, onto production lines that operate more quickly through repetition. 
Maritime employers in British Columbia and the union representing port foremen say they have ratified a new four-year collective agreement, after a dispute that saw workers locked out of container terminals last year. The British Columbia Maritime Employers Association and the International Longshore and Warehouse Union Ship and Dock Foremen Local 514 said in a joint statement that the new collective agreement extends from April 1, 2023, to March 31, 2027. …It is the second major labour deal for Canada’s West Coast ports that will be in place until March 2027, after an earlier agreement with thousands of port workers that was signed in August 2023 following a strike. The details of the new deal with supervisors have not been released, and neither the employers association nor the union representing roughly 700 supervisors immediately responded to requests for comment. They had been without a deal since the last accord expired in March 2023.
In partnership with the Province, the Tahltan, Taku River Tlingit, Kaska Dena, Gitanyow and Nisga’a Nations are kicking off land-use planning in the northwestern corner of B.C., engaging with industry, community and other partners to implement world-leading land-use plans that will provide greater certainty for investors, First Nations and communities alike. Last week, Premier David Eby outlined government’s vision for building prosperity centred on the pillars of economic growth, reconciliation and conservation in northwestern B.C. The vision includes partnering with First Nations to achieve large-scale conservation and strengthen reconciliation envisioned by the Declaration on the Rights of Indigenous Peoples Act (DRIPA). …To that end, over the next year, the Province, Tahltan, Taku River Tlingit, Kaska Dena, Gitanyow and Nisga’a Nations will undertake expedited, inclusive land-use planning and essential stakeholder and public engagement. 
As Premier David Eby and a British Columbia delegation tours Japan, South Korea and Malaysia, Prince George’s opposition MLAs say the trip is “damage control” for his government’s previous policies as well as the reception to the recently passed bills 14 and 15. Eby and a delegation left for a 10-day trip to Japan, South Korea and Malaysia on Saturday, May 31. One notable absence from the trip is British Columbia Assembly of First Nations Regional Chief Terry Teegee, who said in a Friday, May 30 media release that he could not participate in a mission launched by a government that passed legislation trampling First Nations’ rights. Reached by phone on Monday, June 2, Prince George-North Cariboo, Prince George-Valemount and Prince George-Mackenzie Conservative MLAs Sheldon Clare, Rosalyn Bird and Kiel Giddens said the NDP are trying to make up for having closed British Columbia’s independent trade offices in Asia over the last eight years.
New homes development got a shot in the arm this spring with April starts rising in Canada and the United States. Recent reports from TD Economics examined new home data in both markets, finding month-over-month rises in starts for April. In Canada, starts jumped 30 per cent month over month, marking the largest rise since June 2023. Driving growth was the multi-family family segment that saw starts rise 34 per cent, whereas single-family detached home starts gained six per cent from March. …TD noted the “bounce-back” in activity was not unsurprising given levels were so low to start the year. What’s more, housing starts could “be softening,” amid higher construction costs and lower immigration, it cautioned. In the U.S., activity was less robust by percentage growth. Starts there increased less than two per cent month over month.
Weyerhaeuser Company and Firefighter Behavioral Health Alliance (FBHA) today announced an extension of their Fighting Fires Together campaign, a partnership that provides specialized mental health support for wildland firefighters and their families across the Pacific Northwest. Fighting Fires Together, now in its fourth year, addresses the often-overlooked mental health impacts of wildland firefighting in isolated, hazardous and highly stressful conditions. Through a free online resource hub, first responders can find specially designed content, including videos about Post Traumatic Stress Disorder, depression, anxiety and suicide prevention, along with mental health tips, educational articles and contacts for occupationally aware support groups and counselors in Oregon, Washington and British Columbia. Weyerhaeuser’s support for wildland firefighting efforts in the Pacific Northwest began in the aftermath of the Yacolt Burn in 1902, when the company began advocating for Washington’s first forest fire legislation and the funding of community fire prevention education and patrols. 
Canada’s wildfire season has had an early and intense start, with states of emergency declared in Saskatchewan and Manitoba and forecasts warning of severe conditions across central and eastern Canada. Wildfire smoke is already crossing borders, affecting millions. In this Q&A, wildfire experts Dr. Lori Daniels and Dr. Mathieu Bourbonnais, co-directors of the 
Crystal To… is part of a small crew of tree planters who are slowly filling the Whitehorse South fuel break with aspen. It’s her first time doing the job. …The goal of the fuel break is to protect the capital city from wildfires by creating a natural barrier, removing all the highly flammable conifers in an 800-hectare area and replacing them with more fire-resistant aspens. The Yukon government began work on the fuel break in 2020, near the Mary Lake subdivision. It’s one of the first such projects in Canada, and the goal is to have it finished by 2032. The aspens are being planted by the thousands every summer. This year, 232,000 seedlings will be planted.
Following fire mitigation efforts in and around the 108 Mile Ranch, a new generation of trees have been planted to restore the land. West Fraser 100 Mile donated 1,200 trees that were planted by treeplanters from Zanzibar Holdings Ltd. on behalf of the 108 Mile Ranch Greenbelt Commission. Greenbelt commissioner Chris Betuzzi said it’s all part of the commission’s work to secure the 108 Mile Ranch against future fire seasons and avoid a repeat of the 2017 Gustafsen fire, which burned parts of Walker Valley. As a registered forest technologist, he said helping manage the forest is a responsibility close to his heart. In May of 2024, Betuzzi said they carried out fire mitigation efforts in three areas along the Greenbelt, including Donsleequa Road, Qua Place and Gloinnzum Drive to reduce forest fuel in the event of a wildfire. Betuzzi said they had Tsi Del Del Enterprises Ltd come up to process the slash piles and fibre.
are expected to go up around Edmonton this week to capture the emerald ash borer. The shining and dangerous pest is poised to wreak havoc on Edmonton’s $400-million population of ash trees, and the city has two staffers working full time to detect any advance here as the invasive bug closes in from the west or east into Alberta. “We have the largest percentage of our urban forest canopy in green ash of almost any city in North America,” said Michael Jenkins, senior scientist with the City of Edmonton. Ranging from 8.5 mm to 14 mm long and 3.1 mm to 3.4 mm wide, the beetle is difficult to spot. “A single piece of firewood can destroy millions of trees,” warns a poster depicting a stack of ash firewood as dynamite sticks with an emerald ash borer at the tip of the fuse.

The BC government spent a decade killing wolves to protect caribou. Now, critics warn that despite questions about its effectiveness, ethics and impact on the rest of the environment, the government is moving to make the wolf cull a permanent part of its strategy. Launched as a short-term emergency measure in 2015, the decade-long wolf cull is a morally outrageous tactic to divert public attention from the root cause of caribou declines — the province’s failure to significantly address habitat destruction — said Pacific Wild co-founder Ian McAllister. …The future for caribou and wolves is looking even more dire given the federal and provincial plans to fast-track permitting and reduce environmental assessments for development, McAllister said. …The province is looking to make its “short-term emergency” measure of shooting wolves to protect caribou a permanent practice in lieu of protecting habitat, critics warn.
qathet Regional District’s planning committee is recommending the regional board express no objection to a Western Forest Products helicopter logging operation on Powell Lake. At the May 27 planning committee meeting, directors considered a recommendation to advise the provincial ministry of water, land and resource stewardship that the regional district has no objection to the crown land application for a licence of occupation for the purpose of industrial log handling and storage on the northern arm of the lake. Electoral Area A director and committee chair Jason Lennox said there was a detailed staff report on the application. “I’m in support of the recommendation,” said Lennox. “If you read the report, it’s a three-year activity for harvesting into the lake. You will see the different due diligence pieces in there around mitigation measures to the environment; the Powell Region Cabin Owners Association was consulted as well.
British Columbia’s forests are home to a diverse range of wildlife species, which play a significant role in the ecology of a living forest. At the Forest Enhancement Society of BC, we recognize that responsible forest management plays a crucial role in enhancing wildlife habitat and supporting biodiversity. Because of this, one of our key purposes as an organization is to help improve wildlife habitat within B.C.’s forests. Collaborating with the Habitat Conservation Trust Foundation we have supported over 100 wildlife habitat enhancement projects restoring forest health and evaluating the habitat and wildlife response to fire… In this newsletter: Tick Safety from the BC Forest Safety Council; An interview with Thomas Sullivan, Applied Mammal Research Institute; 64 newly funded forest enhancement projects; Lower Nicola Indian Band wildfire risk reduction; and a UBC Faculty of Forestry survey explores interest in international tours.
The Red Flag Warning has been sounded by Alberta Wildfire. But what does it mean? It means conditions are ripe for the ignition and fast-moving spread of wildfires. The forest-fire experts use a sliding scale, first adopted by the U.S. National Weather Service, to determine how dry the conditions are in the forest areas, and how the wind could help fan the flames if that dry tinder is ignited. Basically, a score is calculated based on wind speed, heat and the lack of humidity. A sample document provided by Alberta Wildfire shows a hypothetical watch being created when the maximum daily temperatures is expected to hit 33 Celsius, the humidity is at 25 per cent or lower, and wind speeds are 10 km/h. Basically, when it is punishingly hot and dry, it doesn’t take a lot of wind to trigger an alert. “And, just like weather alerts, “watch” is one level below “warning.”
The Quw’utsun Nation and the Municipality of North Cowichan are moving forward on a co-management framework for the Municipal Forest Reserve. The initiative is being developed with the help of Your Wayfinders Management Solutions, a project management consulting firm. The goal is to create a partnership in key areas like shared decision-making, economic opportunities, Indigenous forest practices, recreation, and stewardship of culturally sensitive areas. A final draft plan is expected by early 2026. In the meantime, North Cowichan has paused new decisions on the forest reserve, but essential activities like FireSmart work and invasive species control will continue. North Cowichan had a technical review and public engagement done for the forest reserve between 2020 and 2023, and a preferred forest management scenario favouring ecological and sustainable values was presented to council.
Climate change has put Western Canada’s glaciers on track for devastating loss over the coming decades, with the southern half of BC expected to lose nearly 75% of the alpine ice — even if warming stops today, a new study has found. The planet has so far warmed an average of about 1.2 degrees Celsius above pre-industrial temperatures. If that increase climbs to 1.5 degrees C, 81% of Western Canadian and US glacier mass would melt, according to the study published Thursday in the journal Science. …Harry Zekollari, the study’s lead author and a glaciologist at Belgium’s Vrije Universiteit Brussel, said the international research team used eight glacier computer models to analyze the potential long-term evolution of the year-round ice. The results painted a dire picture for the world’s glaciers, as the planet has already locked in enough warming to melt 40% of the Earth’s year-round ice by the end of the century.
Boeing Canada says it’s investing millions of dollars into business ventures in B.C. and Quebec with the eventual goal of producing close to 200 million litres of sustainable jet fuel every year. The announcement, made Wednesday, includes nearly $17.5 million split between two projects looking to turn wood waste and carbon captured from industrial smokestacks into sustainable aviation fuel. The fuel, known in industry as SAF, has the potential to reduce carbon emissions by up to 80 per cent over its lifecycle and “offers the fastest route to decarbonization in the aviation sector,” according to Boeing. Boeing’s latest investment will direct $10 million to Project Avance, a joint venture between Bioenergie AECN and Alder Renewables in Port Cartier, Que. The project aims to convert wood residue from sawmills into low-carbon bio-crude that can later be converted into almost 38 million litres of unblended jet fuel every year.
With warmer, drier conditions expected to increase across B.C., people are advised to stay prepared for climate-related emergencies. …People are encouraged to prepare grab-and-go bags, create an emergency and evacuation plan, create an Emergency Support Services profile through their B.C. Services Card app and ensure they have renter’s or homeowner’s insurance for their property. …Warm and dry conditions are expected throughout the province this month, and with that comes an elevated risk of wildfire. Northeastern B.C. is continuing to experience prolonged drought and is expected to remain at high risk for wildfire this summer. …In addition to wildfire risk, the Province is also closely monitoring key indicators of drought risk, including snowpack. 
Fighting forest fires has always been a physically demanding and dangerous job. But it can take a toll on firefighters’ mental health as well. In 2023, the deaths of six wildland firefighters in B.C. highlighted the importance of mental health, both for frontline responders and support staff. Wildland firefighters are challenged with stress and exhaustion, but the loss of colleagues heavily contributed to the mental toll on firefighters during the 2023 wildfire season, said Jessa Barber, a former wildland firefighter who is now a safety officer with the BC Wildfire Service. …BC Wildfire said it is being proactive, implementing policies and practices to support the mental health of its staff. …One of these practices is the New Recruit Boot Camp, which prioritizes educating recruits about the risks and dangers of being a wildland firefighter both physically and mentally. Ongoing support is provided to recruits.
North Cowichan/Duncan RCMP are investigating the drowning of a machinery operator in an industrial incident at the Crofton pulp mill on Wednesday. Police responded about noon to the Catalyst Pulp and Paper Mill after receiving a report that a piece of heavy equipment had fallen into the ocean with its operator trapped inside. Canadian Coast Guard divers attempted a rescue, but the 30-year-old man could not be revived. RCMP spokesperson Alex Bérubé said the B.C. Coroners Service and WorkSafeBC are both investigating what led to “this tragic outcome.”
Saskatoon & Winnipeg — In response to the devastating wildfires threatening communities in central Canada. Dr. Murray Opdahl, a family physician and co-chair of CAPE Saskatchewan said, “It’s a dark day in … with so many of our communities at risk from these devastating wildfires. Wildfires and wildfire smoke pose immediate safety risks, and can have long-lasting impacts on people’s health and mental health. Our communities need immediate support during this crisis. We also need bold action to stop these wildfires from continuing to get worse each year. The science is clear: these increasingly severe wildfires are directly linked to climate change driven by fossil fuel emissions. What we’re witnessing isn’t natural; it’s the result of human activity warming our planet. I’m calling on all governments to take immediate action to protect people on the frontlines of this crisis—and to declare their commitment to accelerate the transition from fossil fuels to safer alternatives.”
In response to the Dryden Creek fire, as this wildfire is called, Squamish Fire Rescue said in a post late Monday night that the District’s emergency response team is working out of the Emergency Operations Centre, located at Fire Hall 1 in Valleycliffe. The out of control fire is located above the eastern end of Depot Road, in the north end of Squamish. It said the BC Wildfire Service has “actively and aggressively” attacked the wildfire thus far by air and with ground crews and would continue to late into the night, and will begin again early this morning. Aerial attack will also resume early Tuesday morning, the post said. Late last night the District of Squamish issued evacuation alerts to those living in properties at the east end of Depot Road, east of Highway 99 including the campground Mountain Fun Basecamp and at the end of Tantalus Road.
Smoke from wildfires in northern Alberta and northeastern B.C. reached Calgary this weekend, resulting in poor air quality in the city through the weekend and into Monday morning. Fire bans remain in effect for a large part of Alberta, including in all of Rocky View County, as six of the province’s forest areas are considered to be at extreme wildfire risk. An evacuation order for parts of the County of Grande Prairie was expanded again late Saturday after the Kiskatinaw River wildfire in B.C. crossed into Alberta Friday afternoon. …As of Monday night, there were 60 fires burning in the province, with 23 of them classified as out of control. More than 615,000 hectares have burned in Alberta so far in 2025. Fire personnel and aircraft from British Columbia, Yukon, Quebec, Nova Scotia, New Brunswick, Washington State, Oregon and Idaho have arrived in Alberta to assist with battling out-of-control blazes.
BC Wildfire Service crews are responding to an out-of-control, 10-hectare blaze south of Sproat Lake on Vancouver Island and say it’s expected to spread. Gordon Robinson, Coastal Fire Centre information officer, tells CHEK News 18 firefighters, three helicopters and a response officer are on scene in the Beverly Main area, west of Port Alberni. The fire currently measures 10 hectares, reads information online. The blaze was discovered on Sunday – and as of around 2 p.m., it’s listed as “out-of-control,” meaning it’s “anticipated to spread beyond the current perimeter or control line. Robinson says the fire is believed to be human-caused because there hasn’t been any lightning in the area. Crews are trying to determine the cause, the BC Wildfire website says, adding that such investigations “often take time and can be very complex.”
Wildfires in Saskatchewan are expected to continue to grow aggressively during the next few days, fuelled by high temperatures, winds and dry conditions. And there’s no sign of relief in sight, according to the Saskatchewan Public Safety Agency. “This will drastically impact our ability to contain some of these fires and will actually cause some of these fires to grow in size over the next period of time,” Steve Roberts, SPSA vice-president of operations, said Sunday. As of Sunday afternoon, 15 fires were burning in the province, down from 17 because two fires have merged and some small fires have been contained, the SPSA said. Roberts said 20 communities are under an evacuation order as of Sunday. The latest evacuation orders have been in Sturgeon Landing and Timber Bay. Thousands of people have already been displaced from their homes in communities including Hall Lake, Pelican Narrows, Creighton, Denare Beach and Weyakwin.
It’s not yet summer, but out-of-control wildfires are raging across Western Canada, fuelled by drought, warmer temperatures and lack of rainfall. Residents in northeastern BC, near Kelly Lake, have fled their homes, as Manitoba and Saskatchewan declared provincial emergencies this week. As of Friday, wildfires in Manitoba had displaced more than 17,000 people. Thousands more have been given evacuation orders because of wildfires in Saskatchewan and Alberta, including 1,300 residents of Swan Hills, a community northwest of Edmonton. …“We did see similar early-season activity like this in the far northeast in 2023 and in 2024 in BC,” said Budd. “That’s really the result of prolonged drought in the region that goes back as early as 2022.” …Manitoba is also facing a dire situation. The Flin Flon fire, located on the Manitoba-Saskatchewan border near Creighton, started at a landfill before crossing over the Manitoba border. It has grown to more than 200 square kilometres.
Fire crews in northern Manitoba have so far been able to contain an encroaching wildfire that forced thousands from their homes, while more residents in Saskatchewan have been told to leave due to a fast-moving blaze. The Saskatchewan government issued an evacuation alert Sunday morning for the dozens of residents that live in the hamlet of Timber Bay. Residents were told to leave the community on their own and head south to a hotel in Regina, about 484 kilometres away, to receive further support. …Approximately 80 people from Timber Bay are the latest to be forced from their homes. In Manitoba, some 17,000 Manitobans have had to leave their homes due to fires. Officials in Flin Flon, Man., where a nearby out-of-control wildfire crews have been trying to keep a nearby blaze at bay, said the fire burning near the mining city has been contained to outside its perimeter highway…
FLIN FLON, Manitoba – Cooler temperatures and a chance of rain this week is expected in a northwestern Manitoba city that’s had to evacuate thousands of people due to wildfire. Environment Canada says temperatures in the mid teens to mid 20s are forecasted this week, with a good chance of rain coming Saturday in Flin Flon. Fire crews have been trying to keep a blaze near Flin Flon at bay, and have said the fire has been contained to outside its perimeter highway. Crews say there have been no structures lost due to the wildfire. More than 17,000 people have been displaced by wildfires in Manitoba, including 5,000 from Flin Flon. Thousands have been affected by wildfires across the Prairie provinces, with Saskatchewan issuing an evacuation alert Sunday morning for dozens of residents in the small northern community of Timber Bay, located about 260 kilometres northeast of Saskatoon.

Saskatchewan is battling the worst wildfire it’s seen in decades — including the 300,000-hectare Shoe Fire in northern Saskatchewan — and experts say it’s largely caused by climate change. “This is classic climate change,” said Colin Laroque, head of soil science and professor at the University of Saskatchewan. Laroque said climatology is studied using 30-year timeframes of weather patterns, which “weren’t that different” until recently. …”These are things that we traditionally saw more in June, July and later summer, when everything dried out and then the fires took off,” Laroque said. Saskatchewan is making its way out of a relatively dry period. Few places had snow for long periods of time over winter. In the past, “snowpacks” would take time to fully melt and trickle into the ground as it warmed up. This would recharge the moisture of the soil.
