Environment Canada issued proposed rules on February 11, 2011, that would align limits on off‑road diesel engines in Canada with EPA standards. They would set new standards for emissions of volatile organic compounds, nitrogen oxides, particulate matter, and other pollutants for 2010 and later-model year off‑road diesel engines used in tractors, bulldozers, log loaders, and other machinery. Environment Canada will accept public comments for 60 days following publication in the Canada Gazette.
