About the Canada Energy Regulator

The Canada Energy Regulator (CER) works to keep energy moving safely across the country. We review energy development projects and share energy information. We enforce some of the strictest safety and environmental standards in the world in a manner that respects the Government of Canada’s commitments to the rights of the Indigenous peoples of Canada. The CER regulates:

  • Oil & Gas Pipelines – Construction, operation, and abandonment of interprovincial and international pipelines and related tolls and tariffs.
  • Electricity Transmission – Construction and operation of international power lines and designated interprovincial power lines.
  • Imports, Exports & Energy Markets – Imports and exports of certain energy products; monitoring aspects of energy supply, demand, production, development and trade.
  • Exploration & Production – Oil and gas exploration and production activities in the offshore and on frontier lands not covered by an accord.
  • Offshore Renewables – Offshore renewable projects and offshore power lines.

Energy Information is one of four core CER responsibilities. We collect, monitor, analyze, and publish fact-based information on energy markets and supply, sources of energy, and the safety and security of pipelines and international power lines. Using tools like interactive pipeline maps and visualizations we make complex pipeline and energy market data user-friendly and accessible.

Our Commitment:
  • Canadians have access to and use energy information for knowledge, research and decision making.
  • Canadians have access to community-specific information about CER-regulated pipelines, powerlines, and other energy infrastructure.
  • Broader and deeper collaboration with stakeholders and partners informs our energy information.

This report, Canada’s Pipeline System 2021: Understanding CER-Regulated Infrastructure System, provides information about major pipelines regulated by the CER.

This report does not indicate whether any application filed with the CER will be approved or denied. The CER makes decisions on specific applications based on the evidence before it at that time. If a party wishes to rely on this report in any regulatory proceeding before the CER, it may submit the material, just as it may submit any public document. Under these circumstances, the submitting party would adopt the material and could be required to answer questions about it.
