Found this on a Canadian Navy history website.
Navy Base firetruck 1966.
The link provides detail as to location and usage.

Obviously not 4X4 ...so guessing Base usage only
Assume some fire-truck company bought a Ford chassis and added the bits and pieces.
Was this a one-off...or a limited production?
The 98036 licence plate is a gift for tracing it's history
