@Labradort - Ontario appears to be the only province [from my research] where you don't need to belong to a club in order to acquire handguns / restricted weaponry.

@Jpnguyento - there are banks [notably in Michigan] that use promotions of giving you a shotgun for opening an account with X-amount of a deposit. Making a trip with a pal, we stopped at a Walmart up in the Sault, and plain as day there was a .22 version of the AR-15.

In response to your #2 Q.... I ordered a few hundred rounds of ammo from [redacted] and both of our paperwork declared a signature being required.
This box could be easily hidden in a backpack, lunchpail or even ripped open and the contents stuffed into pockets.

I mostly work from home and never heard so much as a knock on my door. What got me up was hearing the outside hallway door open and slam shut twice without the general noise people make, and lo and behold, there was my package, left out in the open on the doorstep.
The devil in me wanted to wait a few weeks, then ask about my order, because I hadn't signed for anything, and there was no knock on my door or anything.
But that ain't smart, and afterall, it ain't the company's fault the courier didn't follow instructions.
So what's the take-away here?
Make sure the company uses a good courier, get tracking numbers, make sure they need a signature...and then hope the person delivering it can follow instructions.
