There are a few retailers in Canada who might be able to assist you with your purchase. They are listed on this website in the retailer section. Off hand I do not know what they carry for stock but I do know that they all abide by the airsoft Canada forum age verification policy. Which essentially means that they will only sell to those on this website who have that shiny white age verified banner.
If you are interested in acquiring age verification please consult our frequently asked questions section. If you are the age of 18 or over and have a little bit of time you can be age verified fairly quickly once the information has been submitted by an ASC age verification representative.
Aside from this websites buy and sell section and retailer section all I can suggest is whatever google turns up for you in terms of Canadian retailers for your desired airsoft gun.
