How to Legally Change Your Name in Yukon, the Northwest Territories, and Nunavut

Yukon, the Northwest Territories, and Nunavut each administer legal name changes under their own law, and the three regimes differ in real ways: who handles your application, how long you must have lived there, what it costs, and whether your change becomes a matter of public record.

Three Territories, Three Different Systems

These three jurisdictions are grouped on one page because of population size, not because their laws resemble each other. Yukon and the Northwest Territories both apply through a vital statistics registrar under their own Change of Name Act. Nunavut has never enacted its own Change of Name Act; it still runs on the pre-division Northwest Territories statute it inherited in 1999, and the application goes to a court, not a registrar. Each section below stands on its own. Do not assume a rule from one territory applies to another.

Yukon

What the Law Allows and Who Qualifies

Yukon's legal name change process runs under the Change of Name Act, RSY 2002, c.28, most recently amended by S.Y. 2025, c.5, administered by the Office of the Registrar of Vital Statistics. To apply for your own name change, you must be at least 19, or married, widowed, or divorced (no minimum age applies on that branch), and you must be ordinarily resident in Yukon and have actually resided there for the three months immediately preceding your application.

A parent, or a person appointed to exercise custody rights under the Children's Act, can apply to change a child's name. A child's new surname is limited to that of the mother, the father, a lawful custody holder, or a hyphenation of two of those, so a child cannot be given an arbitrary chosen surname. A child who is 12 or older must consent to their own name change, unless a court dispenses with that consent. The director of family and children's services can apply on behalf of a child in permanent government care.

Yukon's Act, read in full, sets out no criminal record check or fingerprinting requirement anywhere in its text.

The Process, Fees, and Publication

You apply to the Registrar in a prescribed form, stating your present and proposed names, your address history for the past three months, your reason for changing your name, and your date and place of birth, along with any required consents, notices, or court orders, an affidavit of qualification, and the prescribed fee. Yukon's government describes the practical steps as: fill out the adult or dependent-child application form, gather the documentation the form identifies, and submit the application, documentation, and fee to the Office of the Registrar of Vital Statistics, in person at 204 Lambert Street in Whitehorse, by fax, or by mail. The government's own page states processing takes up to six weeks.

The fee is $50, plus $17.50 for each additional family member included on the same application. Since June 30, 2025, that fee is waived entirely, along with related search and certificate fees, for anyone reclaiming an Indigenous name, on self-declaration alone, with no proof of Indigenous identity required. That waiver has a specific statutory basis: a 2025 amendment added a new fees section to the Act stating that no fee is required for any service an Indigenous person requests in connection with reclaiming their Indigenous name.

Your adopted name must include a surname and at least one forename, written in the Roman alphabet, with no initials, numbers, or symbols. Yukon does not currently register a legal name consisting of a single name, though the territorial government's own page says it is working toward allowing that.

Publication in the Yukon Gazette is mandatory. The Act requires the Registrar to publish notice of every name change. A full read of the Act's 23 sections did not turn up any hardship or safety exemption from that publication requirement, of the kind both the Northwest Territories and Ontario write into their own Acts. That absence was confirmed by reading every section, not assumed from a summary; it does not rule out an exemption sitting in Yukon's regulations, which were not part of this review, so treat that possibility as unconfirmed rather than ruled out. If you are changing your name for safety reasons, contact the Office of the Registrar of Vital Statistics directly to ask what options exist before you apply.

Married Yukoners have a separate, lighter-weight option: instead of a full application, a spouse can elect to use their spouse's surname, their own pre-marriage surname, or a hyphenation of the two, through the Registrar. That election reverses automatically on divorce or annulment, without a new application.

Northwest Territories

What the Law Allows and Who Qualifies

The Northwest Territories' Change of Name Act, S.N.W.T. 2007, c.12, took effect April 1, 2008, and has since been amended twice, most recently in 2016. To apply, you must be ordinarily resident in the Northwest Territories, have actually resided there for at least three consecutive months in the twelve months before applying, be a Canadian citizen, permanent resident, or otherwise legally entitled to remain in Canada, and have reached the age of majority, or be or have been a spouse, or have lawful custody of a child. The Registrar General can waive the residency requirement if satisfied that doing so serves the public interest.

For a child, written consent is needed from any other lawful custody holder, any parent with lawful access, the child if they are 12 or older, and the applicant's spouse if the spouse is not the child's parent and the change would give the child the spouse's surname. The Supreme Court can dispense with consent using a best-interests-of-the-child test.

The Northwest Territories is more permissive than Yukon on one point: its Act explicitly allows registering a single name, determined according to the applicant's traditional culture, subject to additional regulatory evidence requirements. As with Yukon, a full read of the Act turned up no criminal record check or fingerprinting requirement.

The Process, Fees, and Publication

Applications go to the Registrar General of Vital Statistics, in an approved form with a statutory declaration covering your names, birth details, address and residency history, spouse details, any child custody or consent particulars, your prior name-change history, and your reason, along with supporting identification and, for a child, proof of custody and consents. The Registrar General can require more information or an in-person interview. Anyone can object to an application in writing, though an objection does not automatically defeat it.

The Act sets a concrete deadline that neither Yukon's nor Ontario's does: the Registrar General must notify you of a decision within 90 days of a complete application. An application can be refused if requirements are not met, or if the Registrar General believes the name could reasonably cause confusion or embarrassment to someone else, or could be used to defraud or mislead the public. A refusal can be appealed to the Supreme Court within 30 days.

Fees, set by regulation rather than printed in the Act itself, are currently $159 for a change of name including one certificate, $64 for each additional person on the same application, $32 for a duplicate certificate, and $26 each for a certified common-law spouse surname declaration or spousal breakdown declaration. Applications go to the Registrar General of Vital Statistics at the Health Services Administration Office in Inuvik, by mail, fax, or email. Separately from any fee waiver Yukon offers, the Registrar General here can also waive fee collection generally to avoid hardship to an applicant.

On publication, the Registrar General must, on registering a change, publish notice in the NWT Gazette and give notice to the Clerk of the Supreme Court, the RCMP, the Maintenance Enforcement Administrator, and any other authority set by regulation. Unlike Yukon, the Act gives the Registrar General real discretion here: notice and publication can be declined if the change is minor, the person was already commonly known by the requested name, or publication or notice would cause undue hardship. Beyond that, the Minister can direct that an applicant's records be sealed entirely, blocking both Gazette publication and notice to authorities, if satisfied the change is intended to prevent significant harm. That sealing power is the strongest safety mechanism found across the three territories' laws. The Act's fraud or misrepresentation penalty tops out at a fine of up to $2,000, well above Nunavut's ceiling; no comparable penalty figure was located in Yukon's Act text for comparison.

A Law Currently Being Rewritten

Treat the Northwest Territories' publication rules as a moving target right now. Bill 40, an amendment to the Vital Statistics Act that also touches the Change of Name Act's notice and publication provisions, passed second reading on February 11, 2026, and was in committee review by mid-March 2026. As introduced, it would let transgender and non-binary applicants request that their name change not be published in the NWT Gazette. In June 2026, the RCMP publicly raised concerns about a related provision, asking legislators to narrow the Registrar General's discretion to withhold notification to police specifically, distinct from the public Gazette notice, citing officer-safety concerns about not knowing a person's criminal-record history under a changed name. As of this writing, the bill had not reached third reading or received assent. If you are relying on the Northwest Territories' current non-publication rules for a safety-sensitive decision, confirm the bill's status directly with the NWT Legislative Assembly before you act.

Nunavut

What the Law Allows and Who Qualifies

Nunavut has never passed its own Change of Name Act. It inherited the pre-division Northwest Territories statute on April 1, 1999, and has amended it only piecemeal since. The most recent official consolidation this research could open directly is printed "current to September 18, 2012," roughly fourteen years old, with its last incorporated amendment dated June 2012. A newer official consolidation is now confirmed to exist on nunavutlegislation.ca (its legal notice is dated June 8, 2026, apparently cited as C.S.Nu., c. C-30), superseding the 2012 text this section relies on. Its substantive content could not be read before publication, both directly and through a read-only proxy, so the residency, fee, and penalty figures below are drawn from the 2012 text and corroborating secondary sources only. Verify any figure that matters to you directly with Nunavut Justice or the Clerk of the Nunavut Court of Justice.

To apply, you must have resided in Nunavut for at least one year before applying, and be either 19 or older, or under 19 and married. That one-year residency bar is the longest of the three territories by a wide margin; Yukon and the Northwest Territories each require three months. If you have not met the residency requirement, the Court can permit your application anyway if it is satisfied that hardship would otherwise result.

For a child, the child's own consent is needed unless they are under 12 or unable to consent because of a disability, along with the other parent's consent, unless that parent lacks custody and is not supporting or has severed the relationship with the child, and a spouse's consent if the change would give the child the spouse's surname. The Court can dispense with any of these consents if the person cannot be found or for other sufficient reason. As with Yukon and the Northwest Territories, the Act contains no criminal record check or fingerprinting requirement, confirmed by reading all 20 sections.

A Court Process, Not a Registrar

Nunavut is structurally different from its neighbors here: your application is filed with the Clerk of the Nunavut Court of Justice, not a vital statistics registrar, along with a $10 fee. The application must state your names, address, date and place of birth, your parents' full names including your mother's maiden name, your spouse's details if married, your occupation, particulars of any pending civil or criminal action or lien against you, your prior name-change history, the consents you have or have not obtained, and your reasons, supported by an affidavit of good faith and a Sheriff's certificate confirming no unsatisfied executions against you.

Anyone can object in writing for a $5 filing fee. If no one objects and the Court is satisfied everything is in order, it grants the application without a hearing; otherwise a hearing is scheduled. The Court must refuse an application if the requested name might reasonably cause mistake, confusion, embarrassment, or inconvenience, was sought for an improper purpose, or is objectionable on any other ground. Once granted, the Clerk sends certified copies of the order to the Registrar General of Vital Statistics and, where a registered lien or judgment is affected, to the Sheriff for re-indexing.

Nunavut's own court website currently returns "page not found" on the change-of-name pages that used to describe this process step by step, which this research treats as a site-navigation problem rather than evidence the process itself has changed. Secondary reporting describes a Form 1 application, two pieces of ID plus a birth certificate, and mailing to a P.O. Box in Iqaluit, but none of that could be confirmed against a live government page, so treat those specific submission details as a starting point to verify with the Court directly, not a confirmed instruction.

Fees and Publication

Beyond the $10 filing and $5 objection fees, an annulment application also costs $5. Penalties here are lower than the Northwest Territories': a fine of up to $500 for fraud or misrepresentation, and up to $100 for failing to comply with an order or demand under the Act; no comparable penalty figure was located in Yukon's Act text for a full three-way comparison.

Nunavut is also the only one of the three territories with no Gazette-publication requirement at all. A full read of the Act's 20 sections found no clause resembling Yukon's or the Northwest Territories' mandatory Gazette notice; the Act's only notice obligations run to the Registrar General of Vital Statistics and, where relevant, the Sheriff, never to a public Gazette. That makes Nunavut's the most privacy-friendly publication regime of the three territories on paper.

Nunavut's process is also entirely paper-and-mail-based and centered in Iqaluit, with no territory-wide network of local registration offices described anywhere in the Act. The Act itself does not address remote community access one way or the other; given that Nunavut has 25 communities, most reachable only by air, that silence is worth noting as a structural gap, not a documented barrier, since no source specifically confirms travel or mail logistics as an obstacle.

Marriage, Divorce, and Assuming a Name Without Applying

All three territories separate an everyday name change from a formal legal one, but each writes the mechanism differently, so do not assume one territory's rule applies to another.

In Yukon, a married person can elect, through the Registrar, to use their spouse's surname, their own pre-marriage surname, or a hyphenation of the two, without a full name-change application. That election reverses automatically on divorce or annulment.

The Northwest Territories runs common-law spousal surname changes on a separate track too: its fee schedule lists a distinct, lower-cost certified common-law spouse surname declaration and a separate spousal breakdown declaration, apart from the fees for a full Change of Name Act application.

In Nunavut, a spouse can change their surname on marriage, or revert to a former surname on divorce, without making a formal application to the Court at all. That is separate from Nunavut's rule for someone actually applying to the Court to change a surname while married, which requires the other spouse's consent or notice unless the couple has been separated more than a year.

After the Change

Once your name change is registered, it takes effect the way each territory's law provides. In Yukon, a change made under the Act is effective for all legal purposes once it is made. In the Northwest Territories, your certificate is admissible evidence of the change without further proof. In Nunavut, a certified copy of the Court's order is conclusive evidence, and you can use it to compel any record-holder, public or private, to update their records once you also show proof of identity. From there, use your certificate to update other identification, such as your territorial driver's licence, your Social Insurance Number record with Service Canada, and your passport.
