Canada: Vehicle Definitions

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:

Notes:
 * 1) 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.
 * 2) Otto-cycle (i.e., spark ignition) engines are typically powered by gasoline, but other fuels may be used
 * 3) "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).
