Before getting married, a valid Ontario marriage licence needs to be obtained. A marriage licence is valid for three months from the date it was issued.

Applicants need to be at least 16 years old to get married in Ontario. If either applicant is under 18 years old, written consent from all parents or legal guardians is required. All parents or legal guardians must complete the Consent of Parents or Guardians to Marriage Form available in our office.

1. What you need to obtain a marriage licence

Print the completed marriage licence application form that is received after completing the online form. Ensure both applicants sign it, and bring this into our office.
  • Provide 2 pieces of valid government-issued identification, no photocopies, for each person getting married. One piece of identification for each person must include their photo.
  • If either applicant is planning to remarry, provide supporting documentation, as noted below. Read more if divorced in Canada, or divorced outside of Canada.
Acceptable Forms of ID:

The first and last names must match on the two pieces of ID being presented. To include a middle name on the marriage licence it must also appear on both pieces of ID.

Planning to remarry

If either applicant is planning on remarrying in Ontario, there are a few additional documents that must provided in addition to the ones listed above.

Widow(er)

If an applicant is a widow(er) they are not required to produce a death certificate to obtain a marriage licence.

Divorced in Canada

The applicant will need to bring official proof of the divorce to apply for a marriage licence. This can be the original or a court-certified copy of one of three documents:

  • a certificate of divorce (Form 36B)
  • the final decree (Decree Absolute)
  • the final judgment

The Certificate of Divorce (Form 36B) needs to be obtained from the courthouse where the divorce took place. To find a courthouse online, select the city, then select the “Family” drop-down to obtain the correct contact information.

A divorce order issued by a judge is different from a certificate of divorce which acts as the proof of a divorce. We can not accept a Judgement, Court Order (Form 25A) issued by the Court or photocopies/certificates certified by a Lawyer or Notary Public. More information is available online. Learn more about the differences and how to obtain a divorce certificate.

Divorced outside of Canada

If either applicant was divorced outside of Canada, you will need to send specific documents to ServiceOntario to prove the applicant(s) is/are no longer married. Once ServiceOntario has confirmed the documents, they will send a Foreign Divorce Authorization to Issue a Marriage Licence letter. This process may take up to 4 weeks and must be completed before applying for a marriage licence at City Hall.

Follow the ServiceOntario instructions if you were divorced outside of Canada to get a Foreign Divorce Authorization letter.

3. After the marriage ceremony

The Office of the Registrar General maintains records of marriages that were officiated in Ontario. For more information call ServiceOntario: 1-800-461-2156 (toll-free). A Record of Solemnization of Marriage may be provided by your marriage officiant immediately following the marriage ceremony. This is a souvenir of the marriage and is not the same thing as a marriage certificate.
