I also ordered mine from Canada without issue. If you’re still having trouble, try going to your profile on Oculus.com. In the Devices section, there was a button to directly apply for the free silicone cover, and when I pressed that, all my info was already filled out and I didn’t have to enter anything. I don’t know if that’s the case for everyone, or only if you’ve ordered hardware directly from Oculus before.
