As Congress returns to Washington, the National Lumber and Building Material Dealers Association (NLBMDA) is urging congressional leaders and the Administration to address growing cost and supply pressures stemming from recently implemented Section 338 tariffs on Canadian building materials. In a 
Indigenous land titles, data centres and human-bear conflicts are among the top-of-mind concerns for municipal politicians, as they gather for their annual fall convention and attempt to influence the provincial government’s agenda. The Union of B.C. Municipalities convention this year is being held in Vancouver from Sept. 14 to 18. … The City of Nanaimo is calling for a ban on exporting raw logs and lumber cants. A cant is a raw log with its bark removed. The motion identifies a lack of adequate and affordable wood fibre supply as a key factor in the continued curtailment or permanent closure of B.C. sawmills and pulp mills. Over the past five years, on average, about 3.2 million cubic metres of raw logs have been exported. The ban would be to “ensure that forests harvested in B.C. from Crown land and private managed forest lands are processed in B.C., encouraging value-added manufacturing in B.C. and supporting employment in B.C.’s forest industry,” the motion states.
American sawmilling is adding capacity faster than it is using it, with 2.1 billion board feet due in the South by 2028, net of every closure already announced. That is according to Forisk, the forest industry consultancy, which tracks more than 2,350 North American mills and logged fifteen sawmill projects in the third quarter alone. “We searched for a buyer… for our mill in Montrose, Colorado,” president Jim Neiman said. Twain Lumber met the opposite condition in Virginia, buying a mill that had been idle since 2024. Twelve of the fifteen projects added capacity, and the three that took it out were all Canadian, with Canfor closing Fox Creek in Alberta for good and Western Forest Products holding Cowichan Bay in British Columbia down since May. Canadian producers have worked both sides of that trade for a decade, and West Fraser shut down 100 Mile House in British Columbia last year while expanding its Henderson facility in Texas.
Consumer inflation held steady at 3% last month compared to a year earlier as higher rent and travel costs offset a slowdown in rising prices for gas and groceries. Statistics Canada says the annual rate of inflation was unchanged from July. The agency says gasoline costs continued to increase in August but at a slower pace, as the conflict in the Middle East continued to weigh on prices. Excluding gasoline, consumer prices rose 2.4% last month compared to a year earlier, up from 2.2% in July. …“Headline inflation remained elevated in August, but core measures continued to show only limited evidence that high energy prices are spilling over into wider inflationary pressure,” said CIBC economist Andrew Grantham. …“With the economic outlook clouded by U.S. tariffs and related uncertainty we think that the Bank of Canada should, and will, keep interest rates on hold in October meeting”.
For decades, architectural sustainability was dominated by operational performance. Better insulation, efficient mechanical systems, photovoltaic panels, passive solar strategies, and high-performance envelopes became the principal instruments for reducing environmental impact. Those measures remain important, but they no longer describe the entire carbon problem. A building can perform efficiently in operation while carrying an enormous historical carbon burden embedded in its concrete frame, steel reinforcement, glass, aluminum, masonry, finishes, foundations, and infrastructure. Once these materials have been manufactured, transported, assembled, and incorporated into a structure, their associated emissions cannot simply be erased by installing efficient equipment. This is where the concept of material memory becomes architecturally significant. Existing buildings contain not only physical material but also the emissions already invested in producing that material. Retaining a structural frame therefore represents more than preservation. It can function as a form of carbon avoidance.
At Stora Enso’s mill in Varkaus, Finland, recovered cardboard packaging is converted into new fibre raw material. The same fibre can be recycled up to 7 times before it becomes too short and weak for further use. The site contains Finland’s largest recycled-fibre processing facility. Covering approximately 3 hectares, it receives used packaging from households, retailers and packaging manufacturers. More than 95 per cent of paperboard and cardboard packaging is recycled in Finland. However, domestic collections do not provide enough material for the mill, which also imports recovered packaging from Sweden and the Baltic countries. Approximately 20 truckloads of recovered material arrive at the site each day. The compressed bales contain products such as milk cartons, pizza boxes and cereal packages.
The Province, in partnership with Na̲nwak̲olas Council, has identified the first candidate area to explore a proposed three-zone forest management model in B.C. The B.C. government is working closely with First Nations, along with industry, local governments and interested parties to identify other candidate areas. Candidate areas will be used to explore a three-zone model for public forests that supports a more co-ordinated approach to land use, stewardship and economic priorities that integrate with ongoing planning processes. The intended outcome is to demonstrate how this model can improve predictability for industry, workers, First Nations, local communities and conservation interests
As part of the City of Rossland FireSmart program, contractors will complete FireSmart fuel treatment projects on municipal land parcels within the community beginning this week. The objective of the fuel management project is to reduce hazardous forest fuels and to decrease wildfire risk to the adjacent residents and the community, noted a release from the city. “The goal for the project is to reduce hazardous surface fuel accumulations close to homes and the community,” it stated. Expected activities include: Reduction of woody surface fuels from tree mortality and winter storm damage; Removal of dead standing trees; Retention of the healthy, large trees to maintain a cool and moist under storey; Retention and protection of all healthy, deciduous trees and shrubs (leaves have a high moisture content and are low flammability); Retention and protection of high value wildlife trees; and Debris disposal (chipping).
