I had heard about this place before, but wasn't completely sure as to its exact whereabouts. One afternoon, while driving to Manitoulin Island, I finally caught a glimpse of it off the embankment as I crossed the bridge.
I entered the small village of Whitefish Falls, and doubled back along a parallel road. This offered me a fantastic view of the old plant from across the water.
I then circled back onto the highway, and found a small driveway just past the bridge. I entered the property on foot, and climbed over the rocks down to the remains of the building. The water was moving surprisingly quickly, and I could make out the shadows of fish apparently sheltering inside the old pipes.
After snapping off some pictures, and taking a moment to admire the local foliage (I swear, I didn't realize that plant was there until someone pointed it out to me afterwards), it was time to continue on my journey.
The man was a genius.
