Environment Minister Jim Prentice announced on May 21 that Canada will impose new emission standards on heavy trucks under the Canadian Environmental Protection Act, 1999. In Canada, the transportation sector accounts for about 25 percent of total greenhouse gas emissions while heavy-duty vehicles account for about 6 per cent of the total greenhouse gas emissions.

The new regulations, a draft of which are expected imminently, would apply to new heavy-duty vehicles and engines manufactured or imported for sale in Canada, starting between the 2014 and 2018 model years, as well as, full-sized pickups, delivery vehicles, buses, freight vehicles, service trucks, garbage trucks and dump trucks. Canada will harmonize its regulations with those being developed in the Unites States.
