DeCew Falls Generating Station No. 2 - 1943

The powerhouse (left) and concrete penstocks (right) of the DeCew Falls Generating Plant.

General Information

DeCew Falls Generating Plant 1, adjacent to this station, is the oldest continually running hydroelectric power station in Canada.


A second phase of the plant, DeCew Falls Generating Plant 2,  was initiated in 1943 to aid in the war effort. It was completed in 1947. Lakes Moodie and Gibson were expanded still further, and Twelve Mile Creek was dredged, widened, and straightened all the way to Lake Ontario.

The old red brick power house contained the original DeCew 1 generators. Adjacent are the newer transformer buildings and powerhouses of DeCew 2.
