Idling Control (By-law No. 2007-266)

The City’s Idling Control By-law (By-law No. 2007-266) prohibits drivers from idling their vehicles for more than three minutes in a given 60-minute period, when the temperature is between 5°C and 27°C (including the humidex calculation and wind chill value as determined by Environment Canada).


  • Idling is allowed during extreme outdoor temperatures to ensure that an occupied vehicle’s interior can be heated or cooled.
  • Exceptions are provided for a number of different vehicles, including:
    • Emergency vehicles
    • Transit buses and vehicles, when picking up and discharging passengers
    • Farm vehicles
    • Vehicles required to remain motionless because of an emergency, traffic, weather condition or mechanical problem, over which the driver has no control.
