canadian made tanks were their engines canadian made or imported

[David_Hayward (RIP)]

The Detroit-Diesel 6-71 engines were all sourced from the Detroit Diesel Plant, in Detroit! The only GMC engines built in Walkerville Plant were 248s, 1940-41. I have never seen any paperwork suggesting that 270 units were ever even thought of being built in Canada, though there is a hint that 248s were to be offered for CMPs in late 1939.
