New Emissions Regs For Canada?

01 April 2019

Environment and Climate Change Canada published the proposed Off-road Compression-Ignition (Mobile and Stationary) and Large Spark-Ignition Engine Emission Regulations in Canada Gazette, Part I.

The proposed new emission standards apply to large spark-ignition (SI) engines and stationary compression-ignition (CI) engines. The regulations would also incorporate the existing standards for mobile off-road CI engines into one regulatory act. The proposed emission standards are aligned with those of the US Environmental Protection Agency (EPA).

The proposed regulations would apply to three classes of engines that are imported into Canada or manufactured in Canada:

Mobile CI engines—Emission standards for off-road mobile compression-ignition engines, as they exist in the Off-Road Compression-Ignition Engine Emission Regulations, are maintained in the proposed regulations. Mobile compression-ignition engines are typically found in equipment used in agricultural, construction, forestry, and mining applications.

Large SI engines developing more than 25 hp (19 kW) of power—New emission standards are proposed that would be aligned with the US EPA Tier 2 standards for mobile large spark-ignition engines. Large spark-ignition engines are used in mobile off-road machines such as forklifts and ice resurfacers.

Stationary compression-ignition engines with a displacement of less than 30 L per cylinder—New proposed emission standards would be aligned with US EPA Tier 4 standards for stationary CI engines. The proposal also provides flexibility in the form of less stringent Tier 2 or 3 standards for stationary CI engines destined for use in remote locations or as back-up sources of electricity. Stationary CI engines are used to provide electricity in remote communities, to drive fire pumps, as a back-up source of power for buildings, and to power irrigation systems, water pumps, compressors, etc.

It is expected that the proposed regulations would come into force approximately 6 months after publication of the final Regulations in the Canada Gazette, Part II, which is targeted for Spring 2020.

The current Off-Road Compression-Ignition Engine Emission Regulations continue to apply until the proposed Regulations come into force.
