Have you ever been on a farm and seen the distances between a home and the fields? And it might confuse you but farmers also do things such as go shopping or on vacation.
And yes, there are laws for storage but you and I both know that they aren't followed because there is no enforcement outside of cases where a problem was identified. I know of two handgun owners in my building and know that one of them keeps his gun in his carrying case instead of keeping it in a safe. A picked lock or conning the concierge and I could have a Sig Sauer in about 20 minutes.
And as handguns have no legal purpose in Canada other than target shooting (barring approved security situations), I see no reason they need to be around.
