As I read the regs you posted, it applies to RIFLES, not handguns.
Read post #8 again. Specifically as it says the definition of unloaded, which it applies to FIREARMS, not differentiating between types of handguns or rifles. The second portion pertains to Restricted firearm transport, which part A is clear on it must be unloaded.
And in case your going to argue it is a antique, here is the regs on that which specifically say it also must be unloaded.
"Antique Firearms
14 (1) An individual may store, display or transport an antique firearm only if it is unloaded.
(2) An individual may transport an antique firearm in an unattended vehicle only if
(a) when the vehicle is equipped with a trunk or similar compartment that can be securely locked, the antique firearm is in that trunk or compartment and the trunk or compartment is securely locked; and
(b) when the vehicle is not equipped with a trunk or similar compartment that can be securely locked, the antique firearm is not visible from outside the vehicle and the vehicle, or the part that contains the antique firearm, is securely locked.
(3) An individual may transport an antique firearm that is a handgun only if it is in a locked container that is made of an opaque material and is of such strength, construction and nature that it cannot readily be broken open or into or accidentally opened during transportation."
So unless it is a non-restricted muzzleloader going to and from hunting sites, the firearm must not have any primed chambers, or cylinders (and lack of a cap doesn't mean it isn't loaded under our law, due to the references above). Pretty clear cut.
