Maybe. Probably. I can't see why not.
Essentially, what's happened here is that the government changed the definition of financial services to exclude credit card surcharge revenue, making these payments eligible for GST/HST. Then they turned around and made a deal with Visa and Mastercard to lower fees for small businesses, but those savings really went to offset Stripe's loss in profit due to the tax change.
It would seem reasonable to conclude that—wouldn't it?
