GST/HST Registry Warning
An August 2012 article by Torkin Manes LLP pointed out that the GST/HST registry only checks the first 10 characters (including spaces) in the business name, so it is possible to get erroneous results from the registry. I checked this and confirmed that the article is quite correct. I entered the GST/HST number of one corporation with the name of a different corporation (first 10 characters of the names identical), and was given confirmation that "the GST/HST number was registered on the transaction date entered". We recommend always saving a pdf of, or printing, the confirmation page for your records, as it may help if the transaction is later questioned by CRA.
For businesses: When dealing with a new vendor, check to see if their GST/HST number is valid. This will help ensure that you will receive your input tax credits.
For individuals: You can check to see if a firm's GST/HST number is valid, so you don't pay GST/HST unnecessarily.
