The temperature hit a high of 32 C in Toronto on Sunday afternoon, as city officials warned residents to mind the toll the heat was taking on them.

Dr. Barbara Yaffe, the city's associate medical officer of health, issued a heat alert on Sunday.

It remains in effect until further notice.

People living in Toronto were asked to check in on family, friends and neighbours to ensure that all are staying cool and drinking enough fluids.

The city issued a news release listing tips for staying cool. They include:

  • Drinking lots of cool water before you feel thirsty.
  • Staying in air-conditioned places.
  • Taking cool showers or baths, or alternatively using cool, wet towels.
  • Wearing light, breathable clothing and using a wide-brimmed hat when outdoors.
  • Staying out of the sun and sticking to the shade.
  • Planning outdoor activities for cooler parts of the day.
  • Taking care to ensure that children, seniors and pets are not left unattended in vehicles.

As the mercury was rising, a few CBC Toronto readers tweeted the ways that they were staying cool. Here's some of the responses that came in:
