Hi there 🙂
Not sure why they don't, but you can log on to ebay.com (your ebay.ca should work fine) and search for the item number you can purchase the items there using the shopping cart. It will work out the same as buying through ebay.ca... just be sure they ship to your location.
I've had to do this a few times.. mystified me as to why as well, but it works! Hope that helps.
