I do not recall any other combatant armed force using canister in WW2...
Soviets had it available in all calibers - 37, 45, 57, 76, 85, 100mm and used it relatively often (about 1/10th as much as HE for 45mm). 76mm after 1941. switched to 10m fused shrapnel instead since canister did not agree with a muzzle break on ZiS-3.
Even post war they developed canister for 115 and 125mm tank guns.
Thank you for that
