Canada's 2003 On-Road Vehicle and Engine Emission Regulations (SOR/2003-2)
The On-Road Vehicle and Engine Emission Regulations (SOR/2003-2), first established in 2003 and last amended on 2022-10-03 (current to 2025-06-09), aim to reduce air pollutant and toxic substance emissions from on-road vehicles and engines in Canada. The regulations achieve this by setting emission limits for specific substances, including hydrocarbons, carbon monoxide, oxides of nitrogen, formaldehyde, and particulate matter. Furthermore, they target the reduction of toxic substances such as 1-3 butadiene, acetaldehyde, acrolein, and benzene indirectly through the established hydrocarbon emission limits. A key aspect of these regulations is the alignment of emission standards and test procedures for on-road vehicles and engines with those established by the US Environmental Protection Agency (US EPA). The regulations primarily affect manufacturers and importers of on-road vehicles and engines, impacting the transport and car manufacturing sectors.
