What is a Statutory Declaration for Application to Change Name (Form 11155E or 11156E) - Adult's or Child's Name
People often get confused when it comes down to the legal process of changing their name in Ontario. At first, it can appear to be a tedious and complex process but if you follow it through correctly, it should become a simple enough task to get it done. So, then, how do you legally change your name? Well, the short answer it depends!
In Ontario, there are several types of name changes that individuals can legally request, as follows:
- Name change due to marriage: A person can take their spouse's surname or combine their surname with their spouse's surname after getting married.
- A person can revert back to their pre-marriage surname after getting divorced.
- Name change for adults (Form 1155E): An adult can legally change their name for any reason, as long as the new name is not for fraudulent or illegal purposes.
- Name change for children: A child's name can be changed by their parents or legal guardians with the permission of the court.
- Gender marker change: An individual can apply to have their gender marker changed on their birth certificate, driver's license, health card, and other identification documents.
- Correction of errors: A person can request a name change to correct an error in their name or the spelling of their name.
It's important to note that the process and requirements for each type of name change may differ, and it is advisable to consult with a legal professional or the Ontario government's website for more information. You can find out more here.
The statutory declaration portion is a sworn statement that confirms that you are legally changing your name and that the information provided in the form is true and accurate to the best of your knowledge. It is generally used to change your name on your birth certificate, driver’s license, and other government-issued documents. As you may be aware, it's a legal process that requires certain supporting documentation and legal procedures to be followed accurately. So, if you're unsure about the process or have any specific questions, it is recommended that you seek legal advice or contact Service Ontario for more information. Nonetheless, we'll try and break it down for you below.
Adult Name Change
There's two different types of forms. Before you can apply, you first need to be 16 years of age or older and have lived in Ontario for the past 12 months. If you are in fact 16 or 17 years old, then a consent must be provided from every individual who has legal custody of you BEFORE you can actually change your name (complete part 3 of the application), in any event, you can use either form (Adult name change or application to change a child's name).
If you are over 18, then use the application to change an adult's name, otherwise if you are under 16, then you use the application to change a child's name. Just so you're aware, there's little differences between the adult and child applications.
Now, if you're married or have signed a Joint Declaration of Conjugal Relationship document, then you are required to complete Part 2 of the application and give notice to your your partner or spouse that you're changing your name.
As it pertains to a police records check, according to Form 11155E (Section D - page 5 of 17, it states as follows, "If you answered “Yes” to questions 2, 3, 4, or 5, you must provide a current original police record check with this application."
In that case you would download and print this form right here and give it to the police force. However, it is your responsibility to ensure this form meets all requirements when you're including it with your application and also ensure that the officer doing the check meets all requirements as outlined in the form, such as, conducting searches on every criminal offence of which the person has been convicted; searching every criminal offence of which the person has been found guilty and has been discharged, except if the Criminal Records Act (Canada) requires that the record be purged; etc.
Once you've completed your 11155E application form and the police check (if required), then you can submit your completed application with $137 payment and any other supporting documents required by mail or in person at the Service Ontario location at 47 Sheppard Avenue East, Unit 417, 4th Floor
Toronto, ON,
M2N 5N1.
If it was approved, congratulations! You'll receive a change of name certificate. This will display your your previous and your new name.
Now, you're at liberty to use this certificate to update your name on various other personal documents, including:
- Driver's license (bring your certificate of name change and other identification documents, such as your current driver's license and proof of address to a ServiceOntario location);
- Health card;
- Passport (applying for a new passport);
- Social insurance number (you will require your certificate of name change, birth certificate and passport);
- Bank accounts and credit cards;
- Your will, insurance policies, and property titles.
It is recommended to review all your personal documents and contact the relevant authorities to update your name accordingly. The requirements and process for updating your name on personal documents may vary depending on the document and the organization involved, and it is advisable to contact each organization for specific instructions.
Every person born in Ontario who changes their name will also get a new birth certificate in their new name. The birth certificate that is automatically issued does not contain parental information. If you wish to apply for a birth certificate with parental information or a certified copy of the birth registration, you can do so by submitting a Request for Birth Certificate application and the associated payment. If you were born elsewhere in Canada, notice of your name change is sent to the vital statistics office in the province or territory (except Quebec) where you were born. You will need to apply to that vital statistics office to obtain a new birth certificate.
Part 4 – Proving How Long You've Lived in Ontario
You must find a guarantor who will confirm how long you have lived in Ontario.

The role of a guarantor varies depending on the context. But for the purpose of name changes, the guarantor must be employed in one of the designated "approved" professions. A comprehensive list of approved professions is available listed on page 11 of the Adult's Name Change Application form (see image above); in essence, anyone registered with a provincially regulated professional organization, who has known the applicant for a minimum of two years, such as a legally qualified medical practitioners, a member of the Law Society of Upper Canada (Lawyers and Paralegals) may serve as a guarantor.

This section is officially called the "Criminal Offence Declaration" and it is required for all adult applicants (18 years of age or older) who are changing their name. In this section, you will need to disclose details of any criminal offenses, including the nature of the offense, the date of the offense, and the sentence or penalty imposed. You will also need to provide information about any outstanding criminal charges that you may have pending. It's important to provide accurate and truthful information , as any false statements could result in legal consequences.

If you do not have any criminal offenses or charges, you need not provide or undergo a police record check.
- Part 2 on the adult’s application

Finally, part 4 is about proving that you've lived in Ontario for at least a year. In this section, you will need to provide the name, address, and occupation of a person who will act as your guarantor for the name change application. A guarantor is someone who can confirm your identity and that the information you have provided in the application is true and accurate. The guarantor must meet certain eligibility criteria, such as being a Canadian citizen who is at least 18 years old and has known you personally for at least two years. They must also not be related to you by blood or marriage, and must not be in a common-law relationship with you. The guarantor will need to sign the application form and provide their own contact information, as well as swear an affidavit confirming the accuracy of the information you have provided. The guarantor may also be required to provide additional documentation or attend an interview with a commissioner of oaths to confirm their identity and eligibility. It is important to choose a suitable and trustworthy guarantor, as their signature and affidavit play a crucial role in the processing of your name change application.
If you do not know anyone that meets the criteria, you can use someone you've known for five years and who's not related to you.
Step 3: Group Supporting Documents Together
In addition to submitting your name change application, it is essential to provide supporting documentation that varies depending on individual circumstances. The required documentation is outlined on page 13 of the application form. We've taken the liberty to break it down for you below:
- For individuals born in Ontario, an original birth certificate or a certified copy of a long-form birth certificate is necessary.
- For individuals born in Canada but outside of Ontario, a photocopy of the original birth certificate or a certified copy of a long-form birth certificate will suffice.
- For those born outside of Canada, a photocopy of the original birth certificate or a certified copy of the birth registration from the country of birth is required. Additionally, a photocopy of Canadian citizenship card/certificate (both front and back), Canadian record of Immigrant Landing, or Permanent resident card (both sides) is necessary. If available, a photocopy of the passport used to enter Canada should also be included.
In the event that any of the aforementioned documents are missing, a written explanation outlining the reason must be provided and signed by the applicant. If you do not want to send your original birth certificate, then you'll likely require a certified copy of this form to be sent. A certified copy is a copy that has been notarized by a notary public. While it is not mandatory to obtain certified copies for this application, some individuals may opt to do so if they wish to retain their original birth certificate.
