Smoky air has returned to southeastern Saskatchewan, and is expected to continue on Tuesday.
Environment Canada's Air Quality Health Index (AQHI) reading at 6 a.m. Monday was a 4 - representing a moderate risk.
Environment Canada says the at-risk population should "consider reducing or rescheduling strenuous activities outdoors if you are experiencing symptoms."
The general population does not need to adjust their outdoor activities unless they develop symptoms, such as coughing or throat irritation.
Environment Canada forecasts the AQHI will rise to 6 on Monday night and into Tuesday, before falling to 4 by Tuesday night.
Ratings of 1-3 are considered low risk, 4-6 are moderate risk, 7-10 are high risk, and 10+ is very high risk.
Twenty-five active wildfires are burning in Saskatchewan, as of Monday morning, according to the Saskatchewan Public Safety Agency. One is contained, while ongoing assessment is being done on the other 24.
