The smell of fire filled the air as thick smoke from wildfires in Canada blanketed part of the Midwest and created hazardous air quality on Tuesday.

The Pollution Control Agency has issued a statewide air quality alert, including all tribal nations, that will be in effect through 6 p.m. Monday due to smoke from the raging wildfires in Canada's Manitoba and Saskatchewan provinces.

An Air Pollution Action Day was called Wednesday morning for the Chicago area and is in effect until midnight, weather officials said.
