EXPLANATORY NOTE

(This note is not part of the Interim Order.)

The Interim Order Modifying the Operation of Certain Regulations Made Under the Canadian Environmental Protection Act, 1999, was made by the Minister of the Environment on October 13, 2026. The Interim Order suspends the application of the greenhouse gas emission standards for trailers in the Heavy-duty Vehicle and Engine Greenhouse Gas Emission Regulations. The Interim Order modifies the operation of the On-Road Vehicle and Engine Emission Regulations to maintain alignment with the U.S. Environmental Protection Agency’s air pollutant emission standards for on-road vehicles and engines and to update references to the U.S. Code of Federal Regulations. The Interim Order also modifies the operation of the Passenger Automobile and Light Truck Greenhouse Gas Emission Regulations to maintain alignment with the U.S. Environmental Protection Agency’s vehicle classifications. Upon approval by the Governor in Council, and in accordance with subsection 163(5) of the Canadian Environmental Protection Act, 1999, the Interim Order will cease to have effect one year after it is made, or the day on which it is repealed, or the day on which the regulations are amended or repealed to give effect to the Order, whichever is earlier.

Coming into force

EXPLANATORY NOTE

(This explanatory note is not part of the notice of intent.)

Description

The notice of intent is an opportunity for the public to comment on the proposed amendments to the Domestic Substances List (DSL), pursuant to subsection 66(1) of the Canadian Environmental Protection Act, 1999 (CEPA), that would add the letter “P” to the identifiers of 167 polymers, as the assessed form of those polymers met the reduced regulatory requirement (RRR) polymer criteria.

Background

The DSL provides an inventory of substances manufactured in or imported into Canada on a commercial scale. A substance not on the DSL is, therefore, a new substance in Canada. Under CEPA, no new substances can be manufactured in or imported into Canada above the prescribed thresholds before an assessment of their potential impacts on human health and the environment has been performed. Reporting requirements for new chemicals and polymers are set out in the New Substances Notification Regulations (Chemicals and Polymers) [the Regulations].

Substances on the DSL are not subject to notification under the Regulations; however, when a substance identifier on the DSL is followed by a regulatory flag (that is letter “S”, “S′” or “P”) this substance is subject to notification under certain circumstances.

The letter “P” after a substance identifier indicates that the substance assessed and added to the DSL met the RRR polymer criteria in the Regulations. Substances that meet the RRR polymer criteria are considered of low concern, which allows for fewer regulatory information requirements than for non-reduced regulatory requirement (non-RRR) polymers. Typically, a substance synthesized in a form that meets the RRR polymer criteria can also be synthesized in a form that does not meet these criteria.

The purpose of the letter “P” is to indicate that any person who intends to manufacture in or import into Canada the polymer in a form that does not meet the RRR criteria in a quantity above prescribed thresholds must submit the information prescribed in the Regulations. Please consult section 4.7 of the Guidance document for the New Substances Notification Regulations (Chemicals and Polymers) for help determining the applicable notification schedule.

Project scope

Environment and Climate Change Canada identified substances that were assessed as RRR polymers and added to the DSL without the letter “P.” Any form of these polymers that does not meet the RRR criteria currently does not require notification. Therefore, it is proposed to add the letter “P” to the identifiers of these polymers to clarify that only the RRR forms of these polymers are on the DSL, as per their assessment, and not the non-RRR forms. The addition of the letter “P” would allow for the environmental and human health risk assessment of any form of these polymers that does not meet the RRR criteria, prior to their manufacture or import in Canada.

Next steps

Within 120 days of publication of the notice of intent, any person may submit comments on the proposed amendments, which will be taken into consideration during the development of the final order. The final order will be published in the Canada Gazette, Part II. Amendments to the DSL are not in force until the order is published in the Canada Gazette, Part II.
