Speed Limiters - Ontario

Effective January 1, 2009, Ontario required speed limiters to be set at 105 kilometers/hour on all commercial motor vehicles, including vehicles entering Ontario from other provinces and from the United States. The requirements apply to all commercial motor vehicles except:

• Buses;
• Mobile cranes;
• Motor homes;
• Vehicles manufactured before 1995;
• Vehicles with a manufacturer’s gross vehicle weight rating under 11,794 kilograms; or
• Ambulances, cardiac arrest emergency vehicles, or fire apparatus.

Vehicles are also exempt if they are:

• Not equipped with an electronic control module capable of being programmed to limit vehicle speed; or
• Engaged in providing relief in an emergency, or involved in situations presenting danger to life, property, or the environment, or operated on behalf of a municipality, road authority, and public utility or of the government of Ontario or of Canada while responding to such a situation.

The Ministry of Transportation-Ontario will be enforcing the speed limiter requirements through the use of hand-held devices that can read the engine settings and through radar enforcement.
