Union Gas was founded as Union Natural Gas Company of Canada Limited on December 19, 1911 through the amalgamation of three southern Ontario local gas distribution companies: Volcanic Oil and Gas Company, United fuel Supply and Ridgetown Fuel Supply. Originally headquartered in Niagara Falls, Union Gas moved its head office to Chatham in 1918 to be closer to the centre of Ontario gas production.

During the 1920s, Union expanded its operations into Sarnia, Wallaceburg and Windsor. From 1930 to 1960, Union continued to expand its operations throughout southwestern Ontario, adding the cities of London, Stratford, Waterloo, Guelph and Brantford.

During this period, a number of strategic facilities expansions took place. In 1942, storage and compression facilities were developed in Dawn Township, south of Sarnia, utilizing depleted underground gas pools. At the same time, pipeline connections to the U.S. Panhandle Eastern Pipeline were built at Windsor for the importation of U.S. gas.

In 1958 a new, 142-mile long, 26-inch diameter transmission pipeline was constructed from the Dawn Compressor station to Oakville, in order to connect Union's system with the TransCanada Pipeline which brought Western Canadian gas to Ontario that year. In 1959 Union Gas extended its system north to Owen Sound. In 1973 an amalgamation with United Gas Limited of Hamilton extended Union's service into that community.

In April, 1985, a significant milestone in Union Gas's history occurs when the 500-thousandth customer is added.

Over the next 30 years, Union continued to enjoy strong growth and distribution, transmission and storage facilities expanded greatly to meet growing customer demand. Assets increased ten-fold from $400 million in 1975 to over $7.2 billion in 2016. A number of key events occurred during this time:

  • In 1985, Union Gas became the wholly owned subsidiary of a newly created parent company, Union Enterprises Ltd. A significant milestone in Union Gas's history occurs when the 500-thousandth customer is added.
  • In 1986, Unicorp Canada Corporation became the controlling shareholder of Union's parent.
  • In 1992 Unicorp sold Union Gas to Westcoast Energy Inc. of Vancouver B.C.
  • In 1994 Union Gas entered into a shared services operating arrangement with sister company and fellow Westcoast subsidiary, Centra Gas Ontario, a natural gas distribution utility serving about 225,000 customers along the TransCanada Pipeline, across northern and eastern Ontario.
  • On January 1, 1998, Union Gas and Centra Gas Ontario were amalgamated, under the name of Union Gas Limited, a company now serving over a million customers from the Manitoba border to the Quebec border, and the industrial heartland of Southwestern Ontario from Windsor to just west of Toronto. Today, with about 2,200 employees working in communities across Ontario, Union Gas is a major employer in the province.
  • On January 1, 1999, Union Gas transferred its retail merchandise programs, including equipment sales, rentals, financing and appliance service programs, to an unregulated energy services affiliate, Union Energy. Union Gas continued to provide safe, reliable and economical delivery of natural gas to customers. In an increasingly competitive energy marketplace, the company has concentrated its efforts on providing high-value energy delivery services to meet the changing needs of customers, including energy retail marketers.
  • With Duke Energy's March 2002 purchase of Westcoast Energy, Union Gas became a Duke Energy company. Duke Energy is a diversified energy company with a portfolio of natural gas and electric businesses, both regulated and unregulated, and an affiliated real estate company headquartered in Charlotte, N.C..
  • On January 1, 2007, Duke Energy spun-off its natural gas business including Union Gas, into a new publicly traded company named Spectra Energy Corp.
