Hi,
I don't think you can direct-list to ebay Canada (yet). As far as I know, you can only list to US, UK, and Australia ebay, and that is set in the "My Account" settings.
However, that's a guess.....and there may be some simple work-arounds. I would open a problem with support. They might have some suggestions, or at least have an idea when they will have ebay Canada submission capability.
