We want you to beat the heat this summer, but there are a few things to remember to stay cool and stay safe.

Be safe

Hazardous air conditioners

Improperly installed window air conditioners are a serious safety hazard to you and your family, and can fall onto other people.

What you need to know:

  • You may be held liable for injuries or property damage from improperly installed window air conditioners.
  • Before you install an air conditioner, you must get permission from the Operating Unit Manager.
  • It must be an energy efficient unit and installed properly according to safety standards.
  • Install window air conditioners over balconies, wherever possible.
  • Self-evaporating floor AC units are easy to install and eliminate the risk of falling. Tenants may consider purchasing and installing floor model units if feasible.

If you have questions about your air conditioner, please contact your superintendent or call the Client Care Centre at 416-981-5500.

Extension cords and fire safety

Fires can start from using the wrong extension cord or by overloading the plugs with an air conditioner or fan.


  • Use a Canadian Standards Associations (CSA) or Underwriters Label (UA) cord that can carry the power load of your air conditioner or fan.
  • Use a CSA-approved power bar with a built-in circuit breaker.
  • Keep cords away from any heat source.
  • Always plug your air conditioner or fan into a three-prong outlet, cord or power bar.


  • Use a damaged or two-prong extension cord.
  • Keep appliances or home electronics running when not in use.

Stay cool

Fan and air conditioner tips

  • Be aware that fans do not cool the air; they just move air around. Don't use a fan to blow hot or warm air on yourself (this can cause heat illness to happen faster.)
  • If you have air conditioning, at night, when the air is cooler, turn off your AC unit and open your windows. This will let the hot air escape and move cooler air in.
  • Please use your air conditioner considerately. Overuse can cause a power outage in your building.

More tips

  • Take cool showers or baths, or mist yourself with cool water.
  • Drink lots of cold fluids, especially water, even if you don't feel thirsty.
  • Close your blinds and curtains to block out the sun during the day.
  • Avoid using your oven to cook meals, as this can make your home hotter.
  • If possible, do most of your cooking at night when the air is cooler.
