Coming into Force

2 This Order comes into force on the day on which it is registered.

REGULATORY IMPACT ANALYSIS STATEMENT

(This statement is not part of the Order.)

Issues

The Minister of the Environment (the Minister) reviewed information on 656 substances found on the Revised In Commerce List and determined that they meet the criteria for addition to the Domestic Substances List, as set out in the Canadian Environmental Protection Act, 1999 (the Act). Therefore, under the authority of subsection 66.1(1) of the Act, the Minister is adding these 656 substances to the Domestic Substances List.

Background

Domestic Substances List

The Domestic Substances List provides an inventory of substances in the Canadian marketplace. It was originally published in the Canada Gazette, Part II, in 1994 and is amended, on average, 12 times per year to add, update or delete substances.

The Domestic Substances List includes eight parts, in which substances are divided based on

Substances new to Canada

Substances that are not on the Domestic Substances List are considered new to Canada and are subject to notification and assessment requirements set out in sections 81, 83, 106 and 108 of the Act, as well as in the New Substances Notification Regulations (Chemicals and Polymers) and the New Substances Notification Regulations (Organisms). The Act and these regulations ensure that new substances introduced to the Canadian marketplace are assessed to identify potential risks to the environment and human health, and that appropriate control measures are taken, if deemed necessary.

For more information on the thresholds and scope of these regulations, please see section 1 in the Guidance document for the New Substances Notification Regulations (Chemicals and Polymers) and section 2 of the Guidelines for the Notification and Testing of New Substances: Organisms.

Revised In Commerce List

The Revised In Commerce List (R-ICL) is an administrative list of substances found in products regulated under the Food and Drugs Act (FDA) and that were in Canadian commerce between January 1, 1987, and September 13, 2001. The R-ICL was initially released on May 3, 2013, and was periodically revised to reflect updates and corrections. On November 3, 2019, the process for nominating substances closed and the R-ICL became a static list. The status of R-ICL substances is communicated via the R-ICL Tracking Table.

Adding substances to the Domestic Substances List

The Minister may add a substance to the Domestic Substances List under subsection 66.1(1) of the Act when the following criteria are met:

Adding 656 substances to the Domestic Substances List

The Minister reviewed information on 656 substances on the R-ICL and determined that they meet the criteria for addition to the Domestic Substances List under subsection 66.1(1) of the Act. These 656 substances are therefore being added to the Domestic Substances List and, as a result, are no longer subject to the New Substances Notification Regulations (Chemicals and Polymers).

The remaining substances on the R-ICL are currently under review to ensure they meet the criteria for addition to the Domestic Substances List. If necessary, assessment and consideration of appropriate risk management measures may be conducted prior to addition to the Domestic Substances List.

When an R-ICL substance is added to the Domestic Substances List, it is removed from the R-ICL.

Objective

The objective of Order 2026-66.1-01-01 Amending the Domestic Substances List (the Order) is to add 656 chemicals and polymers to the Domestic Substances List.

As a result, the substances are no longer subject to requirements under subsection 81(1) of the Act.

Description

The Order is made pursuant to subsection 66.1(1) of the Act to add 656 chemicals and polymers to the Domestic Substances List. A total of 656 substances identified by their Chemical Abstracts Service (CAS) Registry Numbersfootnote 2 are added to Part 1 of the Domestic Substances List.

Regulatory development

Consultation

The Act does not prescribe any public comment period before adding a substance to the Domestic Substances List. As the addition of these substances is administrative in nature and reflects their current commercial status, no consultation period for the Order was deemed necessary.

Indigenous engagement, consultation and modern treaty obligations

Orders amending the Domestic Substances List do not introduce any new regulatory requirements and, therefore, do not result in any impact on modern treaty rights or obligations. As such, specific engagement and consultation with Indigenous Peoples were not undertaken.

Instrument choice

Under section 66.1 of the Act, the Minister may add a substance to the Domestic Substances List when it is determined to meet the criteria for addition. Orders amending the Domestic Substances List are the only regulatory instruments that allow the Minister to implement these duties and functions.

Regulatory analysis

Benefits and costs

Adding substances on the Domestic Substances List is administrative in nature. The Order does not impose any regulatory requirements on businesses and, therefore, does not result in any incremental compliance costs for stakeholders or enforcement costs for the Government of Canada. The Order is expected to facilitate access to 656 substances for businesses, as the substances are no longer subject to requirements under subsection 81(1) of the Act. Adding substances to the Domestic Substances List under subsection 66.1(1) of the Act is a federal prerogative that the Minister can exercise when a substance meets the criteria for addition.

Small business lens

As described in the “Benefits and costs” subsection, the Order will not result in any incremental impacts. As such, the Order will not impact Canadian small businesses.

One-for-one rule

Since the Order does not impose any regulatory requirements (see “Benefits and costs” subsection), it does not impose new administrative burden on business, and the one-for-one rule does not apply.

Regulatory cooperation and alignment, and international obligations

There are no international agreements or obligations directly associated with the Order.

Effects on the environment

In accordance with the Cabinet Directive on Strategic Environmental and Economic Assessment, a strategic environmental and economic assessment is required for initiatives that are expected to have important effects (positive or negative, direct or indirect) on the environment and economy. Since orders amending the Domestic Substances List to add substances do not result in incremental impacts (benefits and costs), a strategic environmental and economic assessment is not required.

Right to a healthy environment

The Government of Canada has a duty, in the administration of the Act, to protect the right to a healthy environment, as provided for under the Act, subject to reasonable limits. In July 2025, the Government of Canada released the Implementation Framework for the Right to a Healthy Environment under the Canadian Environmental Protection Act, 1999 (the framework), which sets out considerations to protect this right and uphold the principles described in the framework.

Many of the elements included in the framework were considered to inform the Order. In line with the framework, a review of the best available science for the substances was conducted to determine whether these substances may pose a potential risk to the environment and human health. Furthermore, the addition of substances to the Domestic Substances List aligns with the framework’s non-regression principle, as this is not expected to lead to a decrease in environmental or human health protection, since these substances are of low concern in terms of posing a potential risk to the environment and human health.

Gender-based analysis plus

Since the Order does not result in incremental impacts (benefits and costs), no gender-based analysis plusfootnote 3 (GBA+) impacts have been identified for the Order.

Implementation, compliance and enforcement, and service standards

Implementation

The Order is now in force. Developing an implementation plan is not required when adding substances to the Domestic Substances List. The Order does not constitute an endorsement from the Government of Canada of the substances to which they relate, nor an exemption from any other laws or regulations that are in force in Canada and that may apply to these substances or to activities involving them.

Compliance and enforcement

Where a person has questions concerning their obligation to comply with an order, believes that they may be out of compliance, or would like to request a pre-notification consultation, they are encouraged to contact the Substances Management Information Line at substances@ec.gc.ca (email), 1‑800‑567‑1999 (toll-free in Canada) or 819‑938‑3232 (outside of Canada).

The Order is made under the authority of the Act, which is enforced in accordance with the Canadian Environmental Protection Act: compliance and enforcement policy. In instances of non-compliance, consideration is given to factors such as the nature of the alleged violation, effectiveness in achieving compliance with the Act and its regulations, and consistency in enforcement when deciding which enforcement measures to take. Suspected violations can be reported to the Enforcement Branch of the Department of the Environment by email at enviroinfo@ec.gc.ca.
