IMO
The de-registration of long guns did not change the fundamental law that anyone owning or carrying a firearm has to have a license to do so. I presume Foreigners(Non-Canadian) will still have to get the paperwork to bringing a firearm as before. BTW. I have to have ATF written permission to bring in a Firearm from Canada which requires type of rifle, where made, serial no, type and amount of ammo, where made and a valid hunting license or written invitation to a shoot.
