You're probably not 18 so you can't buy airsoft at all.
It is also illegal to import any airsoft guns into Canada. They will get seized and destroyed.
If you can't afford a 600$ airsoft gun then you can't afford airsoft.
Besides, as I already said, you're probably too young so just wait until you're 18 or go buy some canadian tire crapsoft.
