Sulphur in Diesel Fuel Regulations (SOR/2002-254)

The goal of the Sulphur in Diesel Fuel Regulations (hereinafter referred to as the Regulations) is to ensure that the level of sulphur in diesel fuel used in on-road vehicles in Canada will not impede the effective operation of advanced emission control technologies planned to be introduced on 2007 and later model year vehicles (i.e., in mid-2006) to comply with stringent new exhaust emission standards. This is accomplished by reducing the maximum allowable limit for sulphur in on-road diesel fuel to 15 milligrams per kilogram of the fuel, which is equivalent to 15 parts per million (p.p.m.), commencing June 1, 2006.
