I would contact Joss & Main - they should know.

I'd call Joss & Main. I wouldn't know, as I don't know anyone in Quebec.

Call Joss and Main, they should know or find out for you. I live in the US, so I have no idea for certain.

Most Likely yes since it is crossing Borders, it all depends on what kind of Item and then they calculate the Import Tax... hope that help but what you save on Joss &Main will help alot

I was charged duty at the time of my purchase, but the laws for transactions to Quebec may be different, as they often are, to those for the rest of Canada. I hope this helps!
