antique firearm means
(a) any firearm manufactured before 1898 that was not designed to discharge rim-fire or centre-fire ammunition and that has not been redesigned to discharge such ammunition, or
(b) any firearm that is prescribed to be an antique firearm; (arme à feu historique)

CC s. 84(1) “prohibited firearm” says, in part:
84. (1) “prohibited firearm” means (a) a handgun that
(i) has a barrel equal to or less than 105mm [4.14″] in length, or
(ii) is designed or adapted to discharge a 25 or 32 calibre cartridge…
Therefore, any handgun that is an “antique firearm” is also a “prohibited firearm” if it has a barrel less than 105mm/4.14″ long, regardless of whether it is a muzzle-loading handgun or a cartridge-firing handgun, and regardless of calibre.
Also, any handgun that is an “antique firearm” is also a “prohibited firearm” if it is “designed or adapted” to use “a 25 or 32 calibre cartridge.”
