Want to change the name of your business in the city’s supplier database? Here is how to do it.

Make sure you have your supplier number on hand. You can locate it on a purchase order, a payment notice or an invoice.

Step 1

Answer “No” to the First 2 questions on the form (in French):

  • Are you a financial or government institution?
  • Do you need to register with the city’s supplier database for a one-time transaction, or to obtain a fee, grant, compensation or financial contribution?

Step 2

Submit the legal documents confirming the name change. If the two companies listed in the Québec enterprise register (old and new name) are still in operation and not related, one of the following documents must be provided:

  • Change of name certificate
  • Sales contract
  • Letter on a letterhead signed by a significant person confirming the change for each company
  • Notarized or lawyer-signed document certifying the change

Step 3

  • Check the box “I want to change my company name” and enter the old name and supplier number.
  • Check “I don’t have a supplier number. You will be assigned a new number

Step 4

Click on “start registration” and fill in the form.

Step 5

Upon receipt of the documents confirming your business name change, the city will make the change and send you a confirmation email.
