Smoke from fires leads to poor air

Environment Canada has issued a special air quality statement for Peterborough and the Kawarthas advising that smoke from forest fires is causing poor air quality and reducing visibility. Similar advisories are now in effect for most of Ontario and Western Canada, though conditions could improve on Tuesday with the passage of a cold front. Environment Canada says the smoke is from active forest fires in northwestern Ontario that have moved over southern Ontario and that reduced visibilities and deteriorating air quality are possible if the smoke descends to ground level.
