Idling Control By-law

To support initiatives to reduce emissions that contribute to climate change and poor air quality, The Town of Grimsby has developed the Idling Control By-law. The by-law states that no person shall cause or permit a vehicle to idle for more than three (3) minutes total in a sixty (60) minute period in an outdoor environment.
