Um, not sure as that would depend on how heavy/ size of package it's shipped out in. I personally don't see it weighting very much. I know shipping in bubble wrap envelopes are much cheaper then shipping in a box for me here in Canada. If you were to ship it out in the very same it could probably classify as letter mail and it would be less then $5.
With shipping to Canada you just need to mail it out from your post office as you need to fill out a customs form which is just your mailing info, my mailing info, estimated value of what's packaged and a ***** description of what's inside.
