The city of Montreal is appealing to the public to help ease winter smog.
A smog alert was issued Monday, primarily affecting the city's east end.
The major culprits are wood burning stoves and fireplaces -- 48% of smog is caused by wood-burning.
Montreal Executive Committee member Alan DeSousa wants Montrealers to find other ways to heat their homes.
Another other major culprit is all those idling vehicles -- idling produces more emissions per minute than driving at average speeds.
The smog is a health concern, especially for elderly people with respiratory diseases.
Hampstead takes action
The town of Hamsptead recently took action against smog.
The town passed a law banning all wood-burning appliances.
