WINONA, Minn. – You don’t need a vacation to see Canada. Nor to smell Canada. Go outside and look and whiff, and you’ll have feel for wildfires in northern Alberta and Saskatchewan. A cold front has moved an unhealthy band of ground-level smoke that’s heaviest in northwest Minnesota but also statewide and into Wisconsin. The smoke should clear rapidly overnight. Meanwhile, the Minnesota Pollution Control Agency has issued an air-quality alert at red in northern areas, a level considered unhealthy for everyone, and orange elsewhere, almost as severe.
