At CFB Borden, north of Toronto, there is a installation museum with a M4A1 Grizzly tank with a 17-pounder Firefly turret. In early 1945, the British Army sent a couple of 17 pounder Firefly turrets with guns to the Canadian and American Armies to test. Three Grizzlies were reconfigured by the Canadians so they could be used as test vehicles.
One of these tracks still survives at CFB Borden.
Canadian forces did use Firefly’s in Europe.
