The short answer:
Airsoft and other replicas are not illegal to own or possess in Canada, they ARE illegal to import (without a very specific and fairly expensive permit). You cannot bring airsoft guns here, but we can bring them there - we just can't bring them back home, even if we already own them.
Long answer is in the FAQ.
