The Canadian Grizzly I Tank replaced production of the Ram Tank at the Montreal Locomotive Works in 1943. Production ran of this modified American M4A1 for 4 months (September – December) resulting in 188 vehicles for the Canadian Army.

The modifications included a Canadian Dry Pin track system, British radio equipment and a 50.8mm smoke mortar mounted in the turret roof. A Self-Propelled Anti-Aircraft Gun version was also built, which had x4 20mm cannons, but only a few were built.
