Updating Your Address on the Registration Certificate

You must update your address on the registration certificate within a month of moving, or you risk a fine. This update can be done online, but a written letter remains useful to clarify a special situation.

This page explains how to make this update, what information to provide, and offers a ready-to-use letter template, plus a tool to automatically generate your personalized letter.

When should you write this letter?

• You recently moved to a new address;
• You had difficulty updating online;
• You need written confirmation of the update;
• You need to clarify the exact move date.

In all these cases, a written letter remains a reliable way to update your file.

Required information to include

• Your first and last name and the vehicle's registration number;
• Your complete new address;
• The actual move date;
• Documents attached (new proof of residence).

The more accurate this information is, the more you avoid any fine for delay.
