Enbridge Gas Inc. serves approximately 75% of Ontario residents. Enbridge Gas and its affiliates deliver safe, reliable service to about 15 million people on Ontario and Quebec through 3.8 million residential, commercial, institutional and industrial meter connections, and distribute about 2.3 Bcf/d (billion cubic feet per day) of natural gas.

Our company's natural gas distribution network also includes ownership interests in:

  • Gazifère, one of two natural gas distributors in Quebec, which serves more than 43,000 customers in the Outaouais region
  • Énergir LP (formerly known as Gaz Métro Limited Partnership), a Quebec-based natural gas distribution company with interests in subsidiary companies operating gas transmission, gas distribution and power distribution businesses in Quebec and Vermont
