Even though out of country retailers will state that they can ship to you and that the have had success and no issues having their items reach their customers you have to pause and remember that these companies are exactly what they are, companies. A lot of these places have a once it leaves their hands its not their problem policy and well often tell potential customers whatever they feel they need to hear in order to make a sale. Despite what an out of country retailer states the hard fact is that airsoft guns fall under restricted area for importation. An American retailer may tell you that have no issues shipping a gun and while that maybe the truth another truth is that you will most likely not receive your item because Canada customs will seize it and destroy it. In some instances you maybe lucky enough to appeal and have the item sent back at your own cost.
As for the Prohibited Goods Permit as mentioned on 007s website, you as a civilian end user will not be able to apply for one unless you are in that type specific business that requires you to have one, you are welcome to look into attempting to get one, however I have to inform you that the processes is lengthy and extremely costly think numbers in the thousands. Also on that note a PAL (Possession and Acquisition License) or a restrict firearm license has no bearing on whether or not you can import an airsoft gun from out of the country.
As it stands the best way to purchase an airsoft gun in Canada at this time is to purchase from existing retailers or purchase from this websites buy and sell section through age verification.
What is this AV that everyone keeps talking about?
This website has a process called age verification, where if you are 18 or older you can meet with a volunteer representative of this website who will meet with you in person, there is no way around this, no phone, no webcam, in person only, where they will require to see a legitimate piece of photo identification. After the process is completed, it can take sometime as this is all volunteer work, you will be granted access to this websites buy and sell section, where you can find both new and used guns as well as parts, for fair and competitive prices. Although it’s not always the case, it is sort of an open market. However age verification is only required to purchase from ASC buy and sell and any of its retailers and a few other non ASC based Canadian sites. If you are not interested in age verification then you will have to do your own ground work to find an airsoft gun.
