Okay, I tried to slug my way through the Criminal Code sections that deal with concealed carry, weapons, and firearms. I think I got buried. From what I can see, here's a summary:
In the Interpretation section:
“weapon” means any thing used, designed to be used or intended for use
(a) in causing death or injury to any person, or
(b) for the purpose of threatening or intimidating any person
and, without restricting the generality of the foregoing, includes a firearm;
Note: this is different from the discussion on page two of this thread by the justices, where the above definition was changed to define a firearms according to section 84)
"firearm” means a barrelled weapon from which any shot, bullet or other projectile can be discharged and that is capable of causing serious bodily injury or death to a person, and includes any frame or receiver of such a barrelled weapon and anything that can be adapted for use as a firearm;
In Section 84(3)a it states ....
(3) For the purposes of sections 91 to 95, 99 to 101, 103 to 107 and 117.03 of this Act and the provisions of the Firearms Act, the following weapons are deemed not to be firearms:
(a) any antique firearm;
The law against concealed weapons is in section 90.
So to summarize, it looks like if it is a firearm, it is a weapon, and antiques are sometimes firearms and sometimes not, but since section 90 is not mentioned as being included in the sections where an antique firearm is deemed not to be a firearm, it appears as if an antique would be included as a 'firearm' in Section 90, provided the definition of a firearms I found is correct, and the judges definition which, supposedly was also from the Interpretation section of the criminal code, was wrong.
However, he's a judge and I'm not. If he was correct, then it looks like an antique firearm is not a firearm ...... or is it?
Also, I didn't read the firearms act, and for the firearms act, Section 84(3)a specifically states that antique firearms are not firearms for the Firearms Act.
Bottom Line: I don't know what's what, and my head is spinning. To be on the safe side, if some canoeists go by in the wilderness and you are packing an antique gun. It seems the law might be saying (but I'm too confused now to know what it is saying) to let them see it and get them all intimidated and nervous, rather than it let your coat hang over it so it is covered up and they can paddle on cheerfully in blissful ignorance that you are packing a 135-year old sixgun on your belt. However, what do I know. I ain't no lawyer. I haven't even discussed the question of intent like the justices did on page two. That makes things even more confused. I don't think any of us 'intend' to worry anyone or do bad things with our antiques. As the justices discussed on page two, there are laws that require us to conceal our firearm in an unnattended vehicle where the intent is good and they say that is okay.
Another bottom Line: I sure don't want to be the poor fellow who makes a legal case out of this. Better to be discrete and let sleeping dogs lie.
