Details

This compendium was prepared by the Competition Bureau Canada as part of Canada’s G7 presidency in 2025. It follows the:

• 2021 compendium prepared by the UK’s Competition and Markets Authority
• 2022 compendium prepared by Germany’s Bundeskartellamt
• 2023 compendium prepared by the Japan Fair Trade Commission

The Group of 7 (G7) countries are Canada, France, Germany, Italy, Japan, the United Kingdom and the United States, as well as the European Union.

On 2 October 2025, the Competition and Markets Authority (CMA), Department for Science, Innovation and Technology (DSIT) and Department for Business and Trade (DBT) attended the Joint Competition Enforcers and Policymakers’ Summit in Ottawa. The Summit was jointly hosted by the Competition Bureau Canada and the Department of Innovation, Science and Economic Development Canada.

Representatives of the other G7 member states, the European Commission, and the Organisation for Economic Co-operation and Development (OECD) also attended the Summit.

Discussions at the Summit focused on digital competition issues, especially algorithmic pricing, and its impact on competition, markets and the economy.

To build on the work of previous summits, G7 competition authorities, led by Canada, updated this compendium. It offers a comprehensive overview of how competition authorities across G7 jurisdictions continue to respond to the challenges posed by digital markets. It also highlights important updates in approaches to both enforcement and policymaking.

The updated compendium is structured around 4 topics:

1. Latest enforcement and advocacy efforts in digital competition issues
2. Examples of strengthening internal capabilities to better deal with digital competition issues
3. Legislative and reform initiatives regarding digital competition issues
4. Examples of collaboration with non-competition agencies and other policy areas

The compendium is designed to help national governments, policymakers, and industry participants, as well as counterpart competition authorities.
