Union Gas was a major Canadian natural gas company based in Ontario. Its distribution arm serviced approximately 1.5 million customers in northern, southwestern and eastern Ontario.[1] Union Gas has been a subsidiary of Enbridge since February 2017, when former parent Spectra Energy merged into Enbridge.[2]
Union Gas Limited and Enbridge Gas Distribution merged under the corporate name Enbridge Gas Inc. on January 1, 2019.[3] Enbridge has since begun to gradually phase out the Union Gas name in favour of its corporate brand.
