You can please some people some of the time, but you can't please all the people all the time.

Such is the case with the proposed bylaw to ban the installation of new wood burning stoves and fireplaces in Montreal.

The city says the stoves and fireplaces increase air pollution, and that banning new installation is a necessary way to curb an increase.

Montreal has experienced 35 days of higher-than-acceptable levels of smog since November. However, the Association of Heating Professionals says banning new stoves will not decrease the air pollution.

"People are going to keep using old stoves and they should be giving incentives for people to replace their old stoves for stoves that do not produce any smoke," said spokesperson Marc Etienne Cantin while at a demonstration at city hall, replete with wood burning stoves. "This is how they are going to clean the air."

He says new stoves reduce 90 per cent of the emissions of older stoves.

That's not acceptable, according to Louis Brisson with the Quebec Lung Association.

"The safe level of particles in the air caused by wood burning is zero," he said. "I took a taxi when I came in here, and I was coughing when I went by those wood stoves burning out there."

The bill is to be tabled tonight by executive committee member Alan DeSousa, and will later face public consultations.
