Toronto is under a smog alert for the second day in a row.

The Ontario Ministry of the Environment issued a smog advisory for Toronto and much of the GTA on

Saturday. The warning, which includes Halton-Peel and York-Durham regions and the city of Hamilton and Niagara, continued Sunday.

The government warned heavy outdoor exercise may cause eye irritation and breathing problems, and everyone is being asked to carpool or take public transit in a bid to “spare the air.”

The air quality is already expected to be poor due to ground-level ozone and pollution from the United States and Ontario. Those high pollution levels are expected to last until Monday.
