All Canada Post postal outlets measure any package "larger than a phonebook".
If the package exceeds it's weight rating for it's size, minimum density will apply.
You pay by dimensional weight.
For example, a 5-pound box shipped air parcel from Vancouver to San Francisco would cost $16.40, but
if the parcel measured 14" x 12" x 12", it'd be "measured" as 12 lbs. and cost $23.80.....
Using Xpresspost USA service, prices also differ from province to province.
Price also depends on which state you ship to.
Xpresspost-USA scenario, same 5lb, 14" x 12" x 12" package, shipped from BC to California - $26.45
Shipped from BC to Louisiana - $28.85
This makes it more difficult to estimate shipping costs accurately.
