The announcement comes the day after amusement park La Ronde said it would cancel fireworks scheduled for Thursday because of air-quality concerns.

Dr David Kaiser, deputy medical director of Montreal's public health department, said fireworks shows can lead to high concentrations of air pollutants in nearby areas.

Environment Canada has issued a smog warning for the Montreal and Laval areas due to fine particulate matter from forest fires.

There are 490 fires burning nationally, with 255 of them considered to be out of control. Quebec's forest fire prevention agency is reporting 110 active fires.

Canada has already surpassed the record for area burned. Nearly every province in Canada has fires burning. A record 30,000 square miles (80,000 square kilometres) of Canada has burned, an area nearly as large as South Carolina, according to the Canadian government. (AP)
