The city of Montreal has moved ahead with a new law to stop any more wood-burning stoves from being installed.

The exception to the rule is stoves that burn pellets. The new law would not extend to stoves that are already installed.

The rule has yet to be ratified, but will be on the agenda at the April 27 meeting.

Alan DeSousa, the executive committee member responsible for sustainable development, says that wood burning stoves and fireplaces are estimated to be the source of 47 per cent of all winter smog in Quebec.
