Emission Regulations

Canadian Vehicle Emissions Regulations

Canada has had national emissions regulations for new gasoline and diesel-fuel road vehicles since 1971. These standards cover crank case emissions, exhaust emissions of carbon monoxide (CO), hydrocarbons (HC), oxides of nitrogen (N0x), diesel particulate matters (PM), evaporative hydrocarbon emissions (HC), and smoke capacity.

Until recently, emissions from motor vehicles were regulated by Transport Canada under the authority of the Motor Vehicle Safety Act (MVSA) of 1970, as amended in 1993. Under this Act, Transport Canada established national emissions standards that govern the design, construction and functioning of on-road vehicles for a specified useful life. The provinces make references to these standards and comply with them. With the recent passage of the proposed amendment to the Canadian Environmental Protection Act (CEPA) in September 1999, automotive emissions regulations have become the responsibility of Environment Canada.

Emissions regulations apply to new vehicles imported into Canada or shipped interprovincially, as well as to used vehicles imported into Canada. The main aim of these standards is to provide health and environmental protection to consumers.

National emissions regulations include measures that complement provincial programs to control emissions from in-use vehicles, as well as federal labeling requirements that establish what emissions control components should be on a particular vehicle. This information is useful for provincial inspection maintenance or anti-tampering programs.
