Is this some type of prototype built for the military?
This photo is part of a file held by the LAC related to the "RCAF - Ottawa Air Station, Rockcliffe, Ontario." Other than that this "Super Car Equipment on 1935 Ford 2 ton truck 157 1/2 inch wheel base" was photographed on 8 Aug. 1935, there is no further information.
Looking at the signs on this "monster truck", it was supplied by the Truck & Tractor Equipment Co. Ltd. of Toronto. It may have no connection whatsoever to the military, I must add.
