How TC Energy’s Global and Regional Structure Works

CompanyData.com shows company profiles like TC Energy’s within a clear, three-level structure: Global, National, and Local headquarters. This makes it easy to see how each business unit sits within the group and the overall TC Energy family.

The three main levels

Global Headquarters — TC Energy Corporation acts as the global headquarters, with its main office in Canada. It is responsible for all subsidiaries and activities around the world.
National Headquarters — These entities manage activities in individual countries and report to the global headquarters. For instance, TC Energy has national headquarters and subsidiaries in Canada, United States, Mexico, and Luxembourg.
Local Headquarters — These are subsidiaries and operating units responsible for running specific projects, pipelines, and assets in their markets, ensuring local compliance and service delivery.

Each company/entity has its own unique identifier. This lets you connect subsidiaries to the parent, follow ownership chains, and use this information in your business systems.

How control is determined

In our data, control is based on ownership. If a company owns over 50% of another entity, that second business is a controlled subsidiary. This approach makes complex structures like TC Energy’s easier to understand and is standard for large groups.
