This is a necessary part of your application. The Parole Board of Canada (PBC) wants to know exactly where you have lived over the past 10 years. There can be no gaps in the history. You MUST include MONTHS as well as YEARS that you moved in and out of each residence over the last 10 years. You DO NOT need to include postal codes, just street address, city and province.
If you are unsure of your 10-year address history you can try to retrieve it via the Ministry of Transportation (as you are required by law to update your driver’s license every time you move). You may also attempt to retrieve it via Revenue Canada (as you are required by law, to fill out your taxes every year and must include your current address with that information). This step cannot be missed or left out, as it is a necessary part of your Pardon/Record Suspension Application. The PBC will NOT accept any application without a complete 10-year address history.
