That being said places like R Nichols are pretty snooty and probably won't sell to a civilian, but they're available all over the place online now that I'm looking. Called a couple US distributors and they said they'll ship to Ontario no problem
JR Nichols , Gaunt and Taragon-Tasse aren't snooty, but they are LE/MIL , air fire ambulance , security firm customer based. I have old friends that manage a couple of these distributors, you could only imagine the nutters that call daily trying to buy a mini14, some body armour, and some flash bang grenades because there are squirrels in the chimney.
Unless your in an industry where armour might be handy, why does any joe public need this stuff? its a rhetorical ask....
