 There were of course Canadian Dodge COE military trucks although I cannot recollect seeing any Canadian Chevrolet or GMC COE MCP trucks.
What the listing above does not mention of course is the 42/43 and 43S open cabs. I have never seen a 41 Cab either! The earliest open CMP cab that I know of is the 42 on the Chevrolet 2-pounder Portees.
