Strategic Advantage in a Changing Market

Canada’s energy sector, which has underpinned the country’s economy for decades, is undergoing significant and rapid transformation. Renewed demand for reliable energy sources is reshaping conventional markets while investment accelerates low‑carbon and emerging technologies. At the same time, sector participants are navigating complex regulatory environments, stakeholder and community engagement challenges, financing considerations and shifting domestic and foreign political landscapes. This period of energy expansion requires proven expertise, disciplined execution and informed, agile decision‑making.

Consistently recognized as a top-tier energy advisor by Chambers Global, Chambers Canada, Legal 500 and IFLR1000, McCarthy Tétrault operates as a nationally integrated platform with a strong sectoral focus on energy and energy infrastructure. Our National Energy Group brings together a multi-disciplinary team with expertise across the full energy spectrum, from oil & gas and LNG to renewable, nuclear and all other power generation technologies, as well as all related transportation, transmission and storage infrastructure. Our lawyers work closely with our Strategic Advisory Group of former senior politicians and public officials, who bring real-time insight into how government decisions are shaped and how policy priorities evolve to assess political and reputational risk.

We move at pace and execute with discipline at every stage of project development, financing, operations and transactions. We help you anticipate risk, secure approvals, build durable partnerships with Indigenous communities, and execute multi‑jurisdictional transactions with clarity.

McCarthy Tétrault has a deep understanding and knowledge of the energy sector which enables them to provide cost-effective, solution-oriented and strategic advice.
