Well you can, but not concealed wandering the streets.
And we are also allowed fire arms as long as you pass these crazy rules.
You can demonstrate a need for one.
You are not a crazy.
The gun and the ammo are stored separately and locked.
Its not a military grade weapon - because why would you need one for sport or farm shooting???
The police come to your house and check all the above.
Ah, I see now. I got Garry Trudeau (Doonesbury cartoonist) confused with Justin Trudeau (some sort of Canadian politician). A common mistake. Garry is actually more well known here in the land of the free.
