Regulations Amending the On-Road Vehicle and Engine Emission Regulations (On-Board Diagnostic Systems for Heavy-Duty Engines and Other Amendments) (SOR/2013-8)

While the majority of heavy-duty vehicles and engines sold in Canada would likely already comply with U.S. EPA standards, it is important to recognize that some of these vehicles or engines sold in Canada may not. The Amendments add the requirement that heavy-duty engines of a specific model year used or intended to be used in heavy-duty vehicles that have a GVWR of more than 6350 kg be equipped with an on-board diagnostic system that conforms to the standards set out in section 18 of title 40, chapter I, subchapter C, part 86, of the Code of Federal Regulations (CFR). This approach seeks to ensure that the specified standards are identical in both countries. Therefore, the Amendments create a level playing field for companies supplying the North American market for heavy-duty vehicles and engines. At the domestic level, it ensures that all manufacturers, importers and distributors comply with the same standards.
