Carrying it in a vehicle is transporting. Transport of an antique handgun requires a locked translucent case. Carrying it loose in the glovebox would be illegal, and when an antique is used illegally it loses it's antique status and reverts back to a real gun in the eyes of the law. Expect concealed weapon, illegal transport, illegal use and illegal possession charges depending on the anti-gun zeal of the prosecutors and police services involved.
You could probably plea bargain to drop most of the charges if you plead guilty to one or two. I expect you would not get more than a few months in remand centre or prison, and a lifetime firearms ban.
Or you could fight the charges. Expect $50,000 or more in costs and no guarantee. I'd actually doubt you could get out of it but the "justice system" in Canada is a crap shoot and nobody can say with certainty. Not very good odds.
So it's probably not a good idea. BTW - please don't do this (or anything else stupid either) with an antique firearm. You''ll just screw it up for the rest of us and really pee off a lot of people.

And even if someone decides that due to the different legal status of their antique they can store it "X" way or "y", the fact is most of your friendly Law Enforcement may not. It does not matter to them or your bank account that you may not be
convicted: RCMP can still
charge you (actually they lay out an information). It is not the RCMP who decides whether to actually charge you, they give that Information to the prosecutor who decides ultimately whether or not to charge you and see you through the system. The Charter is a
shield not a
sword and to raise it you'll have to be charged and be in the system, or at a minimum be remanded for a length of time where you can actually bring it into play (unlikely as they would likely hold you overnight and release on a promise to appear or something to that effect). You can spend a night in prison and even lose your property without your rights being infringed, depending on the facts.
You will not be able to raise the Charter to get you out of a trial or its associated expense. You could only use the Charter card to get you out of custody, should they be holding you unreasonably. Nor will the Charter protect your property. It is highly restricted in its application.
Forget a civil remedy against the RCMP. They are themselves shielded by legislation that limits their liability and makes it very difficult succeed in a law suit. At best you'd be looking at thousands of dollars and likely up to ten years in court - more if the Feds decide the case could set a precedent, in which case they'll bring it to the Supreme Court of Canada, if they don't think they are going to get where they want at the lower courts. Good luck with that. On the cost front and on the simple fact that many of those kind folks remain as appointments under our former Liberal government.
Discretion is the better part of valour
Use them with care and respect and
"quietly", is the way to enjoy your antique...as the folks posting here do
