Environment Canada has issued special weather statements for much of Saskatchewan due to forest fire smoke from the Northwest Territories.
Smoke from the N.W.T., Albert and northern B.C. is pushing into the province and is expected to be widespread by the afternoon.
The B.C. government's wildfire smoke forecast shows the situation becoming more pronounced throughout today.
Mamawetan Churchill River Health Region in northern Saskatchewan says if there's smoke in the air, the elderly, the very young or people with heart conditions should stay inside.
