On May 28, 2025, the Québec government officially adopted Bill 81, An Act to amend various provisions relating to the environment  (the Act, previously referred to as Bill 81), which was introduced by the province's Minister of the Environment and the Fight Against Climate Change in November 2024.

The amendments contained in the Act address six main themes:

  • addition of powers to enact a regulation specifically for heavy motor vehicles
  • imposition of requirements on manufacturers and adjustments to the ZEV standards for heavy motor vehicles

3. Reconciliation between provincial and municipal regulations

  • introduction of the principle of coexistence of provincial regulations and municipal bylaws relating to the environment
  • replacement of the principle whereby provincial regulations take precedence over municipal bylaws on the same subject matter

4. Activities affecting certain environments

  • clarification of the notion of avoidance of damage to wetlands and bodies of water
  • new determination and enforceability of compensation measures for projects affecting certain environments

5. Management of residual materials

  • expansion of the extended producer responsibility (EPR) approach to new products or sectors of activity
  • addition of powers relating to the marketing, distribution and sale of certain single-use products, including their prohibition
  • clarification of certain management powers relating to management organizations and managers of individual recovery and reclamation programs for certain residual materials

  • modification of certain modalities of the ministerial authorization regime
  • clarification relating to the recording of data on contaminated soils and residual hazardous materials
  • addition of enabling powers concerning the fees associated with certain authorizations and the maintenance of contaminants
