Four Ontario electric utilities pursue merger

Toronto, ON - - Four of OntarioÂ’s largest and most successful local electricity distribution companies are working together to form a new utility that would serve almost a million customers in York Region, Simcoe County, Peel Region, Hamilton and St. Catharines.

A proposed merger between Enersource Corporation, Horizon Utilities Corporation, Hydro One Brampton Inc. and PowerStream Inc. would allow a new, larger company to use its collective resources to deliver a favourable impact on distribution rates, more efficient services and innovative technologies for customers.

The four companies have made a commitment to merge and create a new utility. This action flows from the recommendations made by the PremierÂ’s Advisory Council on Government Assets and is in line with the recommendations made in the 2012 Ontario Distribution Sector Review Panel Report. The proposed merger will require negotiation of a definitive agreement that must be approved by all shareholders and will be subject to regulatory approvals.


Enersource Corporation serves over 200,000 residential and commercial customers across Mississauga. It is a diversified energy and technologies company that serves customers through the distribution of electricity and the delivery of services related to the design, operation and maintenance of electrical systems. Ninety percent of Enersource Corporation is owned by the City of Mississauga, and 10 percent is owned by BPC Energy Corporation Borealis, which is part of the Ontario Municipal Employees Retirement System OMERS.
