Call the Régie de l’assurance maladie, or go to its Québec or Montréal office. Be sure to have your health insurance card with you. If you do not have it on hand, give your social insurance number, name and date of birth.
At the same time, the Régie will make the change for the other people living with you. Remember to give their names.
Note
You must notify the Régie of any change of address in Québec. It’s the only way to ensure that you receive a renewal notice before your card expires.
