Canada Post Plugin not working

-- url of the page with the problem -- : www.bityard.com
-- HikaShop version -- : 2.3.5
-- Joomla version -- : 3.3.6

I'm getting this error code.
Logically I think it is looking for the origin address (where the product originates) but I can't seem to find where.
We can ship from Canada and USA so we want to use at least 2 minimum shipping methods.
For orders orginating form the USA, we want to use USPS and UPS
For order originating from Canada, we want to use Canada Post shipping plugin.

Thus, we restricted Canada Post plugin to Canada and the other two to USA.

So, what does this code mean?

Error while sending XML to CANADA POST. Error code: -3000. Message: Origin Postal Code is illegal.
