Alectra was formed on January 31, 2017 by the merger of the municipally owned utilities
Enersource (servicing
Mississauga),
Horizon Utilities (servicing
Hamilton and
St. Catharines), and
PowerStream (servicing multiple municipalities in
York Region and
Simcoe County, including the city of
Barrie). The initial formation of the company was completed with the acquisition of
Hydro One Brampton from the provincial government's
Hydro One on February 28, 2017.
Guelph Hydro (serving
Guelph and
Rockwood) merged into Alectra on January 1, 2019. Following its formation, Alectra continued to hold the 50% ownership stake formerly held by PowerStream in Collus PowerStream (which services
Collingwood and surrounding area) until 2017. Alectra announced on November 9, 2017 that it was selling its ownership stake in Collus PowerStream back to the Town of Collingwood, with the Town announcing that it was selling Collus PowerStream to
EPCOR Utilities. On January 5, 2021, Alectra acquired power restoration company Holland Power Services based in
Maugerville, New Brunswick. Holland Power Services operates throughout the east coast of Canada and the United States and has 5 locations: 1 in
New Brunswick (headquarters), 2 in Ontario, 1 in
Quebec, and 1 in
Maine, USA. On June 10, 2024, Alectra announced their acquisition of another power restoration company, Gagnon Line Construction, based in
Grand Falls/Grand Sault, New Brunswick. Gagnon Line Construction has two locations: 1 in New Brunswick, and 1 in Quebec. The acquisition of both Holland Power Services and Gagnon Line Construction makes Alectra the largest storm restoration company in Eastern Canada. ==Corporate organization==
