No, not rare, in fact the rifle in the stock picture you posted is more rare than yours. Your's is simply a working rifle, if you can find a mag for it. Your's is a military rifle that has been "modified" to be used as a hunting rifle. It probably had a scope on it at one time since the mounts are still attached.
Clean it up, find a mag and you will have a rifle to use (if the bore is good and it shoots straight) or something you can sell for about $100 - $150.
At this point in the discussion, I would suggest you find a good Canadian gunsmith or gunshop at the least, and take your rifle in to make sure you get the right parts. They may offer you $75 on the spot, or maybe not.
