How do I report air pollution from construction vehicles or machinery?

A:

Visible emissions or smoke from vehicles

Heavy duty diesel vehicles must be emission tested annually through the Ontario Government’s Drive Clean Program. Emissions are tested by measuring the density or opacity of the smoke coming from the exhaust, which should be 20% opacity or less. If you see a “smoking vehicle” with black, grey or blue smoke, you can report it to Drive Clean through their online form or by calling their contact centre.

Contact Ontario’s Drive Clean Program:

  • Completing the online form
  • Call the contact centre at 1-888-758-2999

Be prepared to provide the following information:

  • the licence plate
  • a vehicle description
  • the location, date and time of the occurrence
  • the colour of the smoke

Idling vehicles & machinery

If vehicles or other machines have been idling for over 1 minute per hour, this contravenes the Idling Control By-law and it can be reported to the City of Toronto’s Permit Parking office. This applies to construction vehicles and machinery like 'heavy duty' diesel vehicles like dump trucks as well as ‘road-building machines’ like excavators, cranes, bulldozers, compactors, and street sweepers.

You can make a complaint by contacting the City's Permit Parking Office, but this complaint should be issued in real-time while the idling is still taking place. Enforcement officers can only give warnings or fines if the idling vehicle's driver is caught in the act.
