An authorized official needs to marry you to ensure that a marriage is performed properly and legally. There are two types of marriage ceremonies performed in Ontario: One is a Religious Marriage and the other is a Civil Marriage.
Religious marriage: a recognized religious official marries you. That person must be ordained and in good standing with a registered Religious Denomination and will have a clergy number that you can ask to see. Those like myself who work for non-denominational churches many times will offer a more ‘spiritual’ and personalized service.
For those wanting a civil marriage, an Ontario judge, justice of the peace or a municipal clerk under the authority of a marriage licence may perform them. These marriages usually take place at a city/town hall, or in special circumstances can occur at a person’s residence or venue if the justice of the peace or judge is willing to marry you outside of office hours. These weddings although legal are usually not personalized but meet the minimum requirements to be married in Ontario.
