AFAIK Canada is in North America which IMO makes them American too.
This speaks more to your education than to the point at hand. Refunds are NOT confined to US citizens or residents. So, let's figure out if they are confined to Batch I.
North America is a continent not a country. So refunds across the continent have been offered. Which leads me to think post is on the way to other continents maybe.
We also need to consider if those that have received a refund requested one. If not, interesting. If so, did they ask for BTC or did they submit to the rape form?
