Why is Ottawa's air quality so bad?

@mariellequinton It's funny you should mention this... Two nights ago my wife was outside looking at the full moon and she noticed some odd smell, she asked me to come outside and see if I noticed it TOO, and there was a distinct sort of musty smell, for lack of a better description. I was outside this evening, leaving a friend's house near Manotick, and I also thought the air smelled a little peculiar. Not sure what's up though, but I see AccuWeather is reporting poor air quality especially north of Ottawa. Something is up:

@AlexBlock Purple Air has it bad kind of all over the city
