"Breathing in the Canadian wildfires smoke cannot be the new normal," said Candice Miller, Macomb County public works commissioner.

Smoke from wildfires blazing across Canada is once again wafting over huge portions of the Midwest and worsening air quality, with conditions particularly bad on August 1 in Minnesota, Iowa and Illinois.

Smoke from the Canadian Wildfire has caused an unhealthy air quality index rating in the Peoria area, and medical professionals are urging people at high risk to stay inside and filter the air in their homes.
