I looked on the BC hunting regulations and all I could find was this
4A muzzle loader containing powder and shot in the barrel but
unprimed (ie, no powder in the pan of a flint lock or no cap in the
nipple of a percussion lock) is not considered a loaded firearm under
the Criminal Code (Canada).
..
That may be the legal way to do it but it sure isn't a safe way. As someone else noted the sparks from the flint on the frizzen can touch off the main charge even when there's no powder in the pan. And the risk of that occurring is not all that unlikely. I'd suggest that the safe way is to remove the flint as well as the pan charge.
Thanks for the clarification on short term hunting area use and transport there Mooncoon. Not being a hunter I'd forgotten the finer points of when and where.
