It took me more than 5 hours to read this thread and I must say there is load of good information. Thank you guys. However, during the last 20 + pages the discussion went somewhat off topic which normally suggests that the thread has reached the end of its useful life. Yet, I feel that there is some room for more clarity. Here is what I have in mind:
MODE:
At any given time any gun including antiques (note I am not using word "firearm" here) can be in one of the following 3 states:
1. Stored
2. Transported
3. In use
STATE:
At the same time the gun can only have two states: it can be loaded or unloaded (which may or may not be in violation of applicable laws and regulations)
LOCATION:
Legality of the mentioned MODE-STATE combinations also depends on geographic location. What is legal in one area (e.g. on the Crown Land) maybe illegal in another (off the Crown Land or in the Provincial Park such as Algonquin).
INTENT:
This is related to the answers you give to the LEO's questions when he/she is trying to establish your intent / purpose with regards to the observable MODE / STATES. For example, you may say that it is for the purpose of Target Shooting OR you may say that it is for the purpose of Protection from the wild animals.
So, let's assume all other things are being equal; meaning there is no intent to harm or intimidate other people, or to conceal the gun.
Let's start with the easiest case and gradually add some complexity:
1. You are on CL (Crown Land) where it is allowed to target-shoot. You have set up / about to set up a shooting range for target practice (you can prove it by producing some targets you have used etc.). Your gun is in the loaded state and its clearly in use (you are shooting / about to start shooting). Your location is CL, you have all the papers for your antique and your stated intent is target shooting. Plain vanilla case. In my view highly unlikely to cause problems.
2. Now let's make this less obvious. You are hiking towards CL but you are NOT there yet. Your gun is loaded and carried in the holster (is it in use?) When stopped by LEO you state that your intent is Target shooting. I wonder if you are on a shaky ground here since you have not reached your destination yet and you are carrying (using?) a loaded gun. Is your gun supposed to be in the transportation mode until you reach your destination if your intent is Target shooting?
3. Same as #2 except when questioned you say that you are carrying with intent to protect yourself against wild animals. Is this a lawful purpose in the first place? We know that carrying with the purpose of protection against humans is clearly illegal in Canada, so if you are in the bush (that is you Location is not downtown Toronto), and your stated purpose is clearly mentions wild animals are you off the hook? I saw someone posted some email from MNR (but is this all we can point to or there are other things in the law that we could point to?
I wonder if you guys can share your thoughts especially on Scenarios 2 and 3.
