Both Regina and Saskatoon have a higher air quality health index than mega cities like Toronto or Vancouver, as it stands on Monday afternoon
Environment Canada meteorologist John Paul Cragg says the air quality index is considered high risk in the two Saskatchewan cities because of a stagnant air mass that is keeping the industrial and vehicle pollution right above them, as opposed to having it move up and out as it usually does.
Vancouver is reported as low risk, Toronto at moderate risk.
Having an air quality issue at this time of year is fairly unique for Saskatchewan, Cragg says.
Usually they are later in the year during forest fire season.
There was a peak of pollution over the rush hour this morning (Mon) and that is expected to happen again for the drive home, and then the pollution will dissipate tomorrow as a west wind blows through.
