Many fires burning across Canada, forcing evacuations and threatening air quality in the United States, cannot simply be put out, authorities and experts say.

Canada had its most destructive series of wildfires ever, and one expert says the country is currently on track this year to repeat that record-setting wildfire season in 2023.

Canada is facing widespread wildfires. Manitoba and Saskatchewan have declared emergencies. Many residents have been evacuated. Air quality alerts are in effect in the US and Europe. Several parks are closed in Manitoba and Saskatchewan.

Hedge funds boosted their bullish stance on US crude by the most in five months as wildfires endangered Canadian flows and OPEC+ increased production less than some had feared.

More than 200 wildfires are raging across Canada, sending a thick blanket of choking smoke through the U.S. Midwest. Experts says climate change means U.S. residents better get used to it.

An air quality advisory is expected to remain in effect until noon June 6 as Michigan continues to see effects of Canadian wildfire smoke.

Wildfires burning in Canada’s oil-producing region are prompting investors to examine the potential impact to midstream companies.
