I'm in Canada, in the province of Ontario. When selecting the "I'm purchasing as a business" option during Kagi/Orion subscription checkout, I'm unable to enter my business number and proceed with the transaction. The options presented look like they allow either a federal business number and a few provinces, but not Ontario. See screenshots.


(Note that is not my business number, but I receive the same error message when I enter mine.)
I expect Ontario to be in the list of provinces, and accept my provincial business number, and then to be able to complete the transaction.
