Question: how do i find out if someone is registered for gst?
Answer: To check that a supplier is GST/HST-registered: For any new supplier, go to www.cra.gc.ca/gsthstregistry, before you pay them any HST, and enter their name and the GST/HST registration number they give you. The online registry will tell you if the person is indeed registered under that name as of the current date.
