Looks like a 53 235/with Powerglide engine to me. Look for captains bars on the block above the starter. I have one and it has the same small square pipe plug above the distributor (I do not know if later 235s had it). Also 216s had the coil much closer to the distributor (I don't know anything about Canadian 216 engines).
