Other than some issues with eBay tax tables I am not seeing problems with posting listings in US$. Switching the currency tab to US$ I was able to post a listing to ebay.CA in US$ just now.
This was a simple listing so I have to say that there may some other nuances/issues that support is on top of but I am not aware of. I know that there was a problem with some pages displaying all Canadian listings as $Canadian when in fact it was US$.
As always if there are specific issues please file support cases (you guys know this )and your patience is noted and appreciated@!
