Thousands across Canada have been urged to evacuate as the smoke from blazing wildfires endangers air quality and visibility and begins to waft into the US. Some 3,200 residents in northeastern British Columbia were under an evacuation order Saturday afternoon as the Parker Lake fire raged on in the area, spanning more than 4,000 acres. Meanwhile, evacuation alerts are in place for parts of Alberta as the MWF-017 wildfire burns out of control near Fort McMurray in the northeastern area of the province, officials said. The fire had burned about 16,000 acres as of Sunday morning. Smoke from the infernos has caused Environment Canada to issue a special air quality statement that extends from British Columbia to Ontario. …Smoke from Canada has also begun to blow into the US, prompting an alert across Minnesota due to unhealthy air quality. The smoke is impacting cities including the Twin Cities and St. Cloud.
