Canada’s regulations define weight classes for vehicles and engines as outlined below:
|Class||GVWR, kg (lb)|
|Light-Duty Vehicle||≤3,856 (8,500)|
|Light-Duty Truck||≤3,856 (8,500)|
|– light light-duty truck||≤2,722 (6,000)|
|– heavy light-duty truck||>2,722 to 3,856 (6,000 to 8,500)|
|Medium-Duty Passenger Vehicle||3,856 to <4,536 (8,500 to 10,000)|
|Complete Heavy-Duty Vehicle (Otto cycle only)||3,856 to 6,350 (8,500 to 14,000)|
|Heavy-Duty Vehicle/Heavy-Duty Engine||>3,856 (8,500)|
|– light heavy-duty engine||<8,847 (19,500)|
|– medium heavy-duty engine||8,847 to 14,971 (19,500 to 33,000)|
|– heavy heavy-duty engine||>14,971 (33,000)|
- The new “medium-duty passenger vehicle” class is designed to subject heavier passenger-type vehicles, such as vans and sport utility vehicles, to the same set of emission standards as light-duty vehicles instead of the heavy-duty vehicle emission standards.
- Otto-cycle (i.e., spark ignition) engines are typically powered by gasoline, but other fuels may be used
- “Complete heavy-duty vehicle” is similarly a new subclass of heavy-duty vehicle that will be subject to standards and testing procedures resembling those for light-duty vehicles. These types of vehicles are newly subject to chassis-based standards defined in terms of emissions per unit distance (g/km or g/mile) while heavy-duty engine-based standards are expressed in terms of emissions per unit of work (g/MJ or g/bhp-hr).
