The Lambton Generating Station was a coal-fuelled power plant located on the St. Clair River near Corunna, Ontario, delivering up to 950 MW of power to the grid.

The facility had three 168-metre (551 ft) smokestacks, one of which was equipped with flue-gas desulfurization units, commonly called "scrubbers", to remove sulfur oxide.

In 2012, plans were announced to relocate a proposed natural gas-powered generating station, originally intended for construction by Greenfield South Power Corporation in Mississauga, near to Etobicoke's Sherway Gardens, to the Lambton Generating Station site.

[13] Construction in Mississauga had already begun in 2011; the original site selection was cancelled during the October 2011 provincial election with the project becoming a key issue during that campaign and the subsequent 2014 campaign.
