Hi John,
Welcome to the community!
First off, please fill out your profile (Location, .ect) so we can help you better.
Secondly, in order to gain access you must become "Age-verified". Basically you meet with a local representative from Airsoft Canada to confirm your age.
To find out more about that process, check out this link

I know it can seem like a stupid, unnecessary and slow step, but hopefully you can understand the necessity of keeping what looks like real firearms out of the hands of kids.
Once you become age-verified, you will have access to pretty much anything you want.
Just a heads up, due to the nature of importing airsoft into Canada, expect to pay 2 to 3 times the prices you see on American and Hong Kong airsoft websites.
Good luck, and welcome to the community!
Ben
