Quebec forest fires prompt smog advisories in Ontario
Wednesday, July 3, 2013, 9:20 -
On Tuesday, Environment Canada and the Ontario Ministry of the Environment issued a smog advisory for parts of southern and eastern Ontario.
The advisory remained in effect for the region on Wednesday morning.
"The air quality is expected to exceed the poor threshold of 50 due to fine particulate matter created by forest fire smoke originating from Quebec," said Environment Canada in a statement early Wednesday.
As a result, residents are encouraged to spare the air by taking public transit or car pooling.
Officials say when air quality is poor, heavy outdoor exercise may cause respiratory symptoms such as coughing or shortness of breath. People with heart or lung disease including asthma may experience a worsening of their condition.
The higher pollution levels are expected to gradually disperse on Wednesday as a change in wind direction will begin to propel the residual smoke away from the area.
