I just store it like a firearm, trigger lock, secure it into a bag, and have it secure the bag would not be removed easily. (aka 3 locks total: 1 on the gun, 1 on the case, 1 the case to my bed)
Honestly, if we're truly to get airsoft legalize in Canada, (which the only way is to legalize it as free firearm) we need to show that we are responsible. Don't use the law as the standard, its the minimum. Just like keeping your doors lock for your car.
