Environment Canada issued a special air quality statement for much of southern Ontario amid “elevated pollution levels” on Tuesday.

Just after 2 p.m., the weather agency said hot and humid conditions were creating high levels of air pollution.

The statement covers an area stretching from Peterborough in the north down to Windsor in the south.

“Hot and sunny conditions have resulted in increasing ground-level ozone concentrations,” the statement said.
