Yes, that would be the Hiram Walker distillery. The river is about a mile wide and the Ren-Cen is about a mile down river from Walker’s. The current alone took him that far down river.
On Google maps it looks like it was a little more than 1.5 miles with the current for the first leg of the trip. They don’t say where he ended up back in Canada, but if you assume another 1.5 miles, that’s 0.375 miles per beer... Not bad!
