Regulations Amending the Sulphur in Gasoline Regulations (SOR/2015-186)

The Regulations Amending the Sulphur in Gasoline Regulations (the SiGR Amendments) introduce lower limits on the sulphur content of gasoline, from an average of 30 mg/kg to 10 mg/kg, in alignment with the United States Environmental Protection Agency (U.S. EPA) Tier 3 fuel standards. The SiGR Amendments are published with the Regulations Amending the On-Road Vehicle and Engine Emission Regulations and Other Regulations Made Under the Canadian Environmental Protection Act, 1999 (the ORVEER Amendments). Sulphur in gasoline impairs the performance of catalytic converters, the primary emission control devices used on vehicles to reduce exhaust emissions of air pollutants. Accordingly, continuing to take an integrated systems approach with respect to fuels and vehicles is critical to maximizing future reductions in air pollutant emissions resulting from the use of vehicles. The ORVEER Amendments introduce stricter limits on air pollutant emissions from new passenger cars, light-duty trucks and certain heavy-duty vehicles beginning with the 2017 model year in alignment with the United States Environmental Protection Agency (U.S. EPA) Tier 3 vehicle standards. These two regulatory initiatives work in concert to reduce vehicle air pollutant emissions.
