GATINEAU, QC, Nov. 13, 2025 /CNW/ - The Competition Bureau is inviting Canadians to provide comments on its proposed Merger Enforcement Guidelines. This follows an initial consultation held as part of the Bureau's review of its merger guidance in November 2024.
The proposed guidelines update and change the guidelines issued in 2011 to better reflect how the Bureau analyzes mergers following the recent modernization of Canada's competition laws. They also provide guidance for businesses adapted to the modern economy and to the evolving role of digital technologies.
The Bureau invites interested Canadians to provide feedback on any aspect of the proposed guidelines before February 11, 2026, by emailing [email protected]. Each submission received will be published on our website unless the provider requests that it be kept confidential. Following this consultation, the Bureau will publish its final guidelines.
Until the final guidelines are published, the proposed guidelines provide information about how we enforce the amended merger provisions of the Competition Act.
Effective merger control is essential for Canadians to receive the benefits of a competitive marketplace. Anti-competitive mergers can harm the economy, resulting in higher prices, fewer choices, and less innovation.
