Overview
Transport Canada defines vehicle and engine types for the purposes of federal emissions regulations.

Technical Standards
Canada’s regulations define weight classes for vehicles and engines as outlined below:
| Class | GVWR, kg (lb) |
|---|---|
| Motorcycle | ≤793 (1,749) |
| 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) |
Notes:
- 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).
