A hot, sunny summer day has Environment Canada keeping a close eye on the air we're breathing.
The agency has issued a special air quality statement for the Greater Toronto Area.
While midday air quality values in Toronto were in the low risk range (2 and 3), meteorologist Peter Kimbell says there is the possibility that the concentration of the pollutant ozone could push the reading into the high risk zone (7) late in the afternoon.
Kimbell says poorer air quality likely won't disrupt most people's lives.
"The risk of course is mostly for the vulnerable sector of the population. The very young, the very old and those that have respiratory diseases," Kimbell told NEWSTALK 1010 Tuesday. "If you're outside and doing activity...you may want to limit your activity a little bit but we don't want to make it seem like it's that bad."
Still Environment Canada cautions that people may experience increased coughing, throat irritation, headaches or shortness of breath.
