Smoke From Wildfires Affects Hamilton and Niagara Area

Hamilton, Brantford, and Niagara are under an air quality warning from Environment Canada, as smoke from wildfires in northwestern Ontario fills the area.

The Air Quality Index for parts of the region, including Hamilton, Brantford, and St. Catharines, is expected to hit a 10+, or very high risk, on Wednesday.

This wildfire smoke mixed with heat is causing “very poor air quality and reduced visibility” in Hamilton, according to Environment Canada.

The skies over downtown remained hazy and smoky early in the afternoon.

The weather agency suggests that air quality conditions may get better Friday morning. Meanwhile, heat warnings for Hamilton and Niagara were lifted Wednesday afternoon after two days of high humidex.

The agency also warned that heavy smoke means “everyone’s health is at risk regardless of their age or health status.”

In northern Ontario, several communities are facing evacuations due to numerous wildfires burning across the area.

As of Monday night, there were 128 confirmed wildfires in the northwest. Smoke from active fires in both Canada and the United States is visible throughout many regions, according to Ontario’s Aviation, Forest Fire and Emergency Services.
