Now, first off I'm new to this site, and havne't explored everywhere yet, so if I missed a key legal section please refer me there 
Anyway, my buddy and I were looking at picking up a couple 10/22s and decking them out with the Archangel kits, and y'know have a grand old time. However I picked up the new Gun Buyer's Guide and saw this nifty little rifle
The Smith and Wesson M&P15-22. And at an MSRP of $500 USD, how can one go wrong?
But we were just trying to figure out some of the legalities.
First of all are these legal here at all?
Secondly can someone educate me on the OAL and barrel length laws surrounding rimfires? I was under the impression that 470mm was the minimum length for any rifle or shotgun in Canada, but it seems that this is not the case for rimfire rifles?
Um, oh and just anything else you can provide me with would be fantastic.
Thanks in advance!
