A haze of smoke is possible this week as strong winds and wildfires in the west push smoke toward eastern Ontario and western Quebec.

Wildfires have been raging in Alberta, Saskatchewan, Manitoba and northern Ontario, forcing thousands of people out of their homes and causing air quality warnings from northern British Columbia to Thunder Bay.

Environment Canada is predicting an Air Quality Health Index risk of 4 or moderate for Ju 3 and 4 in local hubs Belleville, Cornwall, Gatineau, Kingston and Ottawa. People at high risk — such as those with lung conditions or who are very young or very old — should consider rescheduling outdoor activities if they experience symptoms.
