Association of Major Power Consumers in Ontario records, 1975-1989

The Association of Major Power Consumers in Ontario (AMPCO) was founded as the Niagara Basic Power Users' Association in the early 1960s. It was a coalition of seven companies in the chemical, pulp and paper, and abrasives industries within the Niagara region. The Association was formed to address increasing electricity rates. In 1974, the name changed to the Association of Direct Customers of Ontario. This change reflected the expansion of the regional Association to a provincial one, which grew in response to Ontario Hydro’s proposed rate increases of over 30 per cent. In 1975, the Association adopted its current name. AMPCO continues to advocate for “electricity rates that are competitive, fair and efficient, and a reliable supply of electrical energy across Ontario.”
