Smoke Levels Increase Across Most of Greater Toronto Area, Relief Expected from Afternoon Showers The Greater Toronto Area is once again shrouded in a thick layer of smoke, a grim reminder that climate change is no longer just a threat, but a harsh reality.
Environment Canada has issued an air quality warning, citing the region's summers as increasingly defined by smoke filled skies.
Wildfires in northwestern Ontario are largely responsible for the poor air quality, but they're not an isolated incident. Last year, similar warnings were issued due to forest fires in Quebec and Manitoba.
