Wildfire smoke blanketing much of B.C. causing health concerns, traffic warnings

From his home on the Stellat’en First Nation in B.C., about 160 kilometres west of Prince George, David Luggi can usually see the nearby Fraser Lake and trees on the shoreline. On Sunday, those landmarks were hidden, shrouded by wildfire smoke that has blanketed much of B.C. and spread through neighbouring Alberta and beyond. The smoke has pushed pollution in Calgary and other cities to dangerous levels, and cast an unsettling, spooky haze over almost every part of B.C. …The smoke, meanwhile, is causing health concerns and traffic warnings. Metro Vancouver and the Fraser Valley are under an air quality advisory, with people with medical conditions advised to postpone strenuous exercise. Environment Canada on Sunday issued a similar advisory for Calgary.
