Some guys seem to take great pride in ownership of the documents forced upon us by Liberal Overlords.
Not me, I chuck them all in a ziploc and throw them in the bottom of a range box and forget about them. In the very unlikely scenario that an RCMP wants to inspect my paperwork, he can wait while I dig them out. In over 25 years of firearm ownership I've only had to produce my PAL to peace officers once or twice, always while hunting, never going to the range. I've never had to show my ATT (or carry permit as they used to be called) or a registration certificate.
My PAL goes in my wallet in case I want to buy a gun on a whim.
