How to Change Your Name After Marriage or Divorce in Northwest Territories (2026)
In Northwest Territories, most people do not need a formal legal name change after marriage. You can assume your spouse's surname simply by updating your ID with your marriage certificate. This guide covers the order of operations, the rules specific to Northwest Territories, and a free downloadable checklist.
Assumed surname vs. legal name change
Assumed surname (what most people do): You do not need to apply for a legal name change. You can use your spouse's last name and change all your documents using your marriage certificate as proof.
Legal name change (a separate, formal process): A legal name change through Registrar General of Vital Statistics (Inuvik) is required only if you want to change the name on your birth certificate itself, or to adopt a name not covered by the assumed-surname rule.
Order of operations
Marry
Officiant registers the marriage with provincial Vital Statistics. This takes a few weeks.
Order your marriage certificate
From the province or territory WHERE you married (not the licence -- the registered certificate issued by Vital Statistics).
Update your SIN (Service Canada)
Free. Can run at the same time as step 4. Your SIN number does not change.
Update provincial driver's licence + health card
Critical: do this BEFORE the passport application. Use your marriage certificate.
Apply for a new passport (IRCC)
Only after provincial ID already shows the new name. Full fee -- no amendment option. Fee as of 2026-03-31: $163.50 (10-yr) / $122.50 (5-yr); indexes annually.
Update CRA, banks, employer
None of these update automatically. CRA: phone (single name) or mail/fax (both names). Banks: online or branch.

Federal steps (same everywhere)
SIN — Service Canada
FreeUpdating your legal name on your SIN record is required by law. Your SIN number does not change. Bring your marriage certificate (or legal change-of-name certificate/court order) showing both old and new name, plus primary and secondary ID.
Online (~5 business days), by mail (~20 business days), or in person at a Service Canada centre.
A name change with Service Canada is NOT automatically shared with CRA or your bank -- update each separately.

After provincial IDA name change requires a NEW passport at the full fee -- there is no amendment or reduced rate. Submit your marriage certificate or divorce order / resumption-of-surname certificate / court order.
Your submitted provincial ID must already show the new last name before IRCC will accept the application. Update your driver's licence and health card FIRST.
Fee as of 2026-03-31: $163.50 (10-yr adult) / $122.50 (5-yr adult). Passport fees index annually under the Service Fees Act. Verify the current fee on the IRCC website before applying.
IRCC live fee pageCRA (Canada Revenue Agency)
CRA cannot update a name fully online. Changing a single name (first OR last) can be done by phone. Changing both names requires mail or fax with a vital-statistics name-change certificate or court order.
Recommended: update your SIN first, then call CRA to confirm (SIN may auto-notify CRA). Takes 4-6 weeks.
CRA does not share your name change with other departments. Update banks, employer, and other accounts separately.
