Heating (Minimum temperatures)

A landlord is responsible for providing heat to a residential dwelling at a minimum of 21 degrees Celsius between September 15 and June 1 of each year. There are time periods during this stretch of time when the weather can be a bit warmer (September 15 to October 15 and May to June 1), which can cause the temperature indoors to be above 21 degrees Celsius, resulting in uncomfortable living conditions for tenants.

If the weather outside means that apartment units are 21 degrees Celsius without heat, property owners and landlords can turn the heat down or off.

If the heating/ventilation system is out of service and currently being repaired/maintained, this is NOT a violation, and no investigation is required.

If you have concerns about the heating or cooling in your rental unit, you should inform the superintendent, the property manager, and/or the proper owner in writing.


  • If the issue is not addressed within a reasonable amount of time, you can submit a service request online at https://www.toronto.ca/311 to file a complaint. A service request will be submitted for investigation by Municipal Licensing & Standards
  • The Heating By-law does not apply to common areas (hallways, stairwells, building entrances, etc). The By-law only applies to the dwelling unit. If there is heating equipment in common areas, so long as the equipment is in good working order (Property Standards By-law requirement), there is no minimum temperature that applies to these areas.

Complaints about no/low heat for commercial properties should be referred to the Ministry of Labour under the Occupational Health and Safety Act.
