A somewhat nearby spot marked on google maps as mowat 45.557693,-78.725364 I wonder what the connection could be, if there even is one.
Sorry... I don't know how to find coordinates, but if you scroll the map down to the main body of the lake, Hayhurst Point is the large peninsula where the Cairn is and the Mowat townsite is directly west of there. The road that ends by the lake is where the mill was. algonquinmap.com (western section)
If you have exact coordinates, please provide them. Thanks.
Map location is incorrect, change the map view to satellite view and follow the road on the west side of Canoe Lake. The end of the road was the site of the Gilmour Mill and after it was demolised, the second Mowat lodge was built there.
