My entering Canada story….
This past fall, I drove up to Quebec city just for a visit but with a cheap crappy old double barrel shotgun, hoping to also go hunting on Iles d"Orleans once I got there. I checked the website and thought it would be alright. I declared that I had the shotgun and wanted to fill out the form. The agent asked if I had made arrangements to hunt, and I informed him that this was a spur-of-the-moment trip and I planned to ask the concierge to call a guide once I got there. He said that wasn't good enough and proceeded to tear my car apart and conduct a full background search. He took me inside and asked me about my past. I told them I had a trespassing conviction for pool-hoping when I was 18, and a pot-possession from when I was about 21 - both of which they found out about. He then tried to trick me up with questions about any DUI's, but I didn't have any. He said that neither of those is a reason not to admit me to Canada but he was obviously interested in DUI's.
They said they could not admit me with the gun and that I could not surrender it to them. I tuned around, went back through US security, threw the gun into the woods, and reentered Canada ten minutes later.
I would love to go hunting in Canada, but why put yourself through that crap - we have plenty of good hunting on this side of the border, too. If that's the way they treat hunters, they don't deserve our business.
It's really funny too, because they give residency to non-Americans who then proceed to make a living steeling people's bags from hotels and other petty and not-so-petty crimes and barely punish them and certainly don't deport them.
Don't know if that helps you any.
