A three-day-long smog warning that has swept across Montreal other parts of Quebec is now in effect in Gatineau, Environment Canada said Tuesday.
Residents can expect poor air quality with high concentrations of fine particulates in the air through Tuesday evening.
Wood heating seems to be the culprit behind the cold weather smog, which is why people living in Montreal have been told for the past three days not to use their wood-burning stoves or fireplaces until the warning is lifted.http://www.cbc.ca/news/canada/ottawa/quebec-smog-warning-gatineau-1.4401613
