Enbridge operates a vast network of midstream infrastructure, primarily engaged in the transportation of hydrocarbons across North America, connecting the United States and Canada. This extensive pipeline system encompasses the critical Canadian Mainline, dedicated conduits for regional oil sands production, and numerous natural gas transmission lines. Beyond its expansive pipeline operations, the company also holds substantial interests in natural gas distribution, notably overseeing Canada's largest firm in this sector and managing a regulated natural gas utility. Furthermore, Enbridge maintains a more modest, yet developing, renewable energy portfolio, which primarily consists of wind power projects, both onshore and offshore.
