How many Canadian tanks were blown in ww1?

Answer 1

If by blown, you mean blown up, then the obvious answer is 0. The Canadian Tank Corps of World War One had never reached operational status and never participated in actual combat. The first battalion was still in the UK training on the Mk V tank when the war ended. Battalions two and three were still being organized. At that time, the British Mk V tank was leading edge technology. The Canadian Army on the mainland was supported by tanks of the British Army, operated by British crews and support. The tanks were returned to the UK when the Canadian Tank Corps was disbanded in 1920. Some training was also being done on the French FT - 17 as well, but again, none saw operational service.

Former american army examples of each tank were acquired in the late 1930's to begin training a new armour corps for the Canadian Army, as World War Two was commencing.
