Sounds like a 235, but the stamped number appears to be a replacement or remanufactured block stamping if US block, or it may just be a Canadian block, which used a different sequence numbering system (likely, given your location). I don't have much info on the Canadian block engine numbers, but someone else may. It also seems to me (foggy memory) that some Canadian 216s may have used the shorter side cover... others will know.
Next best bet is to look for the block casting number, low and in front of the distributor, passenger side.
A bit more info on the block date can be found in the cast date code behind and slightly above the starter. It will start with something like CON 3 (ignore) then a letter number sequence, which is the date code. Letter for the month, next one or two digits for day of the month, and last number the last number of the year cast (eg, a last digit 3 would indicate a '53 casting date).
