You've been around for a while but Its never too late to learn.
Airsoft Canada as a community has decided that the sale of restricted components and guns is to be limited to people whom have been verified to be age 18 or older. To get age verified you will need to contact a local AV rep for your area and arrange to meet them. After this point you may use the classifieds and AV area to gain insight as to where to buy the appropriate receiver.
If this is insufficient or you do not wish to undergo the AV process then sadly we cannot assist you with obtaining what you seek and thus you will be left to your own resources to find what you want elsewhere.
