Environment Canada says wildfire smoke from northern Alberta is causing poor air quality and reduced visibility in parts of northeastern British Columbia.

Special air quality advisories are in place for the North Peace region and Fort Nelson, B.C.

The weather service says wildfire smoke can be harmful and everyone should try and find a place where they can get clean, cool air.

More than 29,000 Albertans have been ordered to leave their homes in recent days due to dozens of wildfires.

Two out-of-control fires are also burning in northeastern British Columbia.

Evacuation orders or alerts remain in place for much of the areas surrounding the Red Creek and Boundary Lake fires, about 1,300 kilometres northeast of Vancouver.
