Are u kidding, man?!!! If someone gave me that as advice, I'd be better off selling the damn thing!!! Just about any reputable gun shop in Canada that deals with restricted firearms will most certainly have Beretta as one of its "stock" firearms, and they will also have the means of acquiring you these mags. If they don't, call the next dealer on your list...you're bound to find one that will be able to help you out. The Beretta 92 is one of the most popular handguns around...and yes, in Canada too!
Give Wolverine Supplies a call...they'll be able to get you whatever you want for your 92A1, and then some. They may even have the 92 mags in stock...
My 2 cents...
