As stated in the title, when a Canadian customer attempts to check out on my site vapesales.com they are confronted with:

United States Postal Service We are unable to find a USPS shipping quote suitable for your mailing address and the shipping methods we typically use.
If you prefer to use USPS as your shipping method, please contact us for assistance.
(Please check that your Zip Code is entered correctly.)

My ZC developer worked on this with no joy. Spoke to USPS and they stated that it definitely was a Zen Cart issue and they denied any involvement with Benghazi. I turned on debug. I get a Funk and Wagnall's size document in XML that means as much to me as the periodic table of elements. I tried to attach it but THAT errored out.

So, any help would be dearly appreciated.
