You can apply for a marriage licence at the municipal offices in your city, town, village or township if there is a license issuer OR you can download the Marriage Licence Application Form and bring it with you to your nearest municipal office.
Fill out the application and then apply for the marriage licence in person. Make sure you and your partner bring identification, such as a birth certificate (along with any change of name certificates), current passport, Record of Immigrant Landing or Canadian citizenship card and photo ID to prove your current legal name and age.
