Bill S-5, Strengthening Environmental Protection for a Healthier Canada Act received Royal Assent on June 13, 2023. This Bill modernizes the Canadian Environmental Protection Act, 1999 (CEPA or the “Act”) by recognizing, in its preamble, the right to a healthy environment as provided under the Act, strengthening Canada’s chemicals management regime and increasing transparency in the way it is administered.
The Government of Canada is working to implement the modernized Act through the development of various initiatives for which there are opportunities for public input and participation. These initiatives include frameworks, policies, strategies, regulations, and processes.
Planned public consultation opportunities
The following list enumerates the timing of public consultation opportunities for upcoming initiatives that will support a strengthened and modernized CEPA. All consultations listed below will be for 60 days unless noted otherwise.

Key initiatives
Right to a healthy environment
The Government of Canada has developed an Implementation framework for the right to a healthy environment under CEPA ; that sets out how the Government of Canada will consider the right in the administration of the Act to fulfill the Government’s duty to protect the right. The Framework considers comments received during the public comment periods on a discussion document , which closed in April 2024, and the draft implementation framework , which closed in December 2024.

Strengthening Canada’s chemicals management regime
The Government of Canada has developed a multi-year, integrated Plan of Priorities (the Plan) that outlines risk assessment priorities and other key initiatives that support chemicals management. These initiatives include information gathering, research and monitoring, risk management, and risk communication. The Plan also links to a Strategy to guide the replacement, reduction or refinement of vertebrate animal testing under CEPA, as outlined below. The Plan considers comments received during the public comment period on the proposed Plan, which closed in December 2024 . Comments were summarized in the What we heard: Proposed Plan of Priorities report.

Increasing transparency - The Watch List
The Watch List is a new requirement under CEPA that seeks to provide greater transparency in the identification of substances of potential concern to interested parties and the public. The Government of Canada is developing the Watch List Approach, which describes the considerations and processes by which the Watch List will be administered. The Watch List includes substances that have been assessed as not currently meeting the criteria for toxic substances under S.64 of CEPA that may be of potential concern if exposure or hazard characteristics were to change in the future.

Integrated Chemical Mixtures Project
In 2023, Environment and Climate Change Canada launched the Integrated Chemical Mixtures Project. The Project aims to develop an approach to increase our understanding of the effects from real-world chemical mixtures that may be present in the environment. New information generated will support the protection of the environment and human health from harmful chemical substances.
