Did Canada use the M1 Carbine in the Korean War?

I was looking through my grandpa's old photo albums and there's a picture of him holding (what I think) is an M2 Carbine. It was taken during the Korean War, and he served with 2 Bn, Royal Canadian Regiment. There's a little writing down at the bottom that says, "Chai-Li, October 51'." I honestly don't know if it's a Lee-Enfield rifle or an M2. Can someone help???
