21 November 2011

On November 17th, 2011, Environment Canada approved amendments to the Off-Road Compression-Ignition Engine Emission Regulations which align Canadian emission standards with the US EPA Tier 4 standards for nonroad engines. The Tier 4 standards will come into force on January 16th, 2012 and apply to engines of the 2012 and later model years manufactured on and after January 16th, 2012.

The approved amendments also include Temporary Standards—that came into effect immediately on November 17th, 2011—that allow companies to import “Tier 4 flexibility” engines into Canada. These Temporary Standards are replacing the Interim Order issued in December 2010 that allowed the sales of engines with US EPA emissions labels in Canada.

Once the Tier 4 regulations are in force (January 16th, 2012), the Temporary Standards will cease to have effect. At that time, the import of these engines will fall under the updated Transition Engines provisions. These provisions allow the continued import of these engines and incorporate new reporting requirements.

The approved regulatory text is expected to be published in the Canada Gazette, Part II on December 7th, 2011.
