Im not sure what you have to deal with in Canada as far as buying and selling online but i have bought & sold online alot,,,to date i have not had one problem with any of the deals & i have saved alot of money. Most online purchases i have had give you a 3-5 day time period to inspect the gun & if there is anything within reason that you do not like about it you just simply send it back to the seller & he will refund your money. Between my Dad & I we have either bought or sold 100 times with no problems. My only suggestion to you would be to know the gun your going to purchase before doing so,,,such as make,,model,,, caliber,,,looks & feel,,,handle one at your local dealer so you know what you should expect the gun or bow to be like,,,also you can research make & model #'s before buying to make sure that there is no factory recalls such as trigger or safety mechanisms failure that you would have to have fixed once owned. I would shoot ya some good websites in this post but im not sure if that is allowed
hope this helps
