Anyone who misses an INFOPASS appointment should/may reschedule the appointment on their own, or the customer may go to the office where the appointment was originally scheduled, with the appointment notice for today.
It is unknown how long this procedure will be in place, but this alert will be updated daily until the situation changes.
