1960 Canada’s first gas turbine cogeneration systems are installed by the Department of National Defence on the DEW line in northern Canada.

1962 Canada’s first nuclear power plant begins feeding electricity into Ontario Hydro’s grid.

B.C. Electric and the B.C. Power commission are amalgamated to form a new Crown corporation, the British Columbia Hydro and Power Authority.

1971 The first two units of Churchill Falls hydro plant achieve full power. The first large industrial cogeneration plant is built by Dow Chemical in Sarnia, Ontario.

1973 The first four units of the Pickering nuclear plant are completed.

1974 With the addition of nine units, Churchill Falls becomes the largest hydroelectric plant worldwide.

1974 With the addition of nine units, Churchill Falls becomes the largest hydroelectric plant worldwide.

1980 Medicine Hat, Alberta, replaces coal-fired steam units with Canada’s first gas turbine, combined cycle cogeneration system.

1984 Nova Scotia Tidal Power Corp. builds North America’s first tidal generating station.

1986 Hydro-Quebec builds the Kuujjuaq Wind Turbine demonstration project.

1993 Cornwall Electric in Ontario installs Canada’s first municipal district energy cogeneration plant. The first wind farm, capable of generating 19 megawatts, is built at Pincher Creek, Alberta.

1998 Six Toronto-area utilities merge. The Toronto Hydro-Electric Commission becomes the fourth largest electrical utility in Canada and the second largest electricity distribution utility in North America.

Alberta passes the Electric Utilities Amendment Act to begin the process of deregulation by separating the functions of generation, transmission and distribution.

Ontario becomes the second province to support industry deregulation and passes the Energy Competition Act.

Canadian Hydropower Association is formed.

2002 In May, Ontario opens its market to wholesale and retail access.

In December, Ontario implements a price cap on electricity rates, halting efforts to deregulate the electricity market. Transmission and distribution rates are frozen at existing levels until May 2006.

2003 Alberta establishes the Alberta Electric System Operator (AESO) to manage the competitive electricity wholesale spot market and the province’s electricity transmission system.

2004 Ontario passes the Electricity Restructuring Act, which empowers the Ontario Power Authority to ensure adequate long-term supply and regulate prices in consumer-oriented electricity sectors.
