Overview of the Act

The Marriage Act of Ontario serves as the definitive legal framework for the solemnization and registration of marriages within the province. Its primary objective is to ensure that all marriages are performed by authorized individuals and recorded accurately in the provincial vital statistics. The Act operates in tandem with federal laws, such as the Marriage (Prohibited Degrees) Act, but remains the primary authority for the administrative procedures required for a legal union in Ontario. A core component of the Act is the determination of legal capacity to marry. In Ontario, the age of majority for marriage is 18. Individuals aged 18 and older may marry without parental interference. The Act permits those aged 16 and 17 to marry only if they obtain written consent from both parents or legal guardians. If a parent is deceased or unavailable, the Act provides specific protocols for substitute consent. Crucially, the Act strictly prohibits marriage for anyone under the age of 16; no judicial or parental consent can override this standard, reflecting a policy of protecting minors from premature legal commitments. The Act defines two categories of authorized officiants: religious and civil. Religious officials must be members of a recognized religious body and registered with the Office of the Registrar General. The Act details how religious bodies can nominate members for registration and the grounds upon which registration may be revoked. Civil marriages are performed by judges, justices of the peace, or municipal clerks (and their designates). This dual system ensures that both secular and religious preferences of the population are accommodated. Before a ceremony occurs, the Act mandates a verification process, usually involving the issuance of a marriage licence. Applicants must visit a municipal clerk's office and provide sworn affidavits regarding their eligibility, including proof of identity and a declaration that there are no legal impediments, such as an existing marriage or a prohibited familial relationship. The marriage licence is valid for 90 days. If the ceremony does not occur within this window, the licence expires. An alternative to the licence is the publication of banns, a traditional religious method where the intent to marry is announced during worship services. The Act requires documentation to prove the banns were read correctly. The ceremony itself requires at least two competent witnesses. During a civil ceremony, the Act prescribes specific wording where the parties declare their intent to take each other as lawful wedded spouses. Post-ceremony, the officiant must maintain a marriage register and ensure the spouses, witnesses, and the officiant sign both the licence and the register. The officiant has a legal obligation to mail the completed licence to the Office of the Registrar General within 48 hours. One of the most significant sections is the Good Faith provision (Section 31), which protects the validity of a marriage if the parties believed the officiant was authorized, even if a technical defect existed in that authority. Finally, the Act includes enforcement mechanisms and penalties for making false statements or performing unauthorized ceremonies, ensuring the integrity of the provincial marriage record.

Getting Married in Ontario — ServiceOntario Guide

To get married in Ontario, couples must be at least 18 years old, or 16-17 with written parental consent; marriage under 16 is prohibited. The practical process begins with obtaining a marriage licence from a local municipal office, which requires two pieces of government-issued identification for each person (e.g., passport, birth certificate). The licence is valid for 90 days from the date of issue. Marriages can be performed by registered religious officiants or civil officiants (such as judges, justices of the peace, or authorized municipal clerks). Remarriage requires specific documentation: those divorced in Canada must provide the original or a court-certified copy of their Certificate of Divorce, while those divorced outside Canada must obtain a 'Foreign Divorce Authorization' from the Office of the Registrar General. For widows and widowers, no death certificate is required at the application stage, but the date and place of the spouse's death must be provided. Registered Indians under the Indian Act may be eligible for a reduction in the provincial portion of the marriage licence fee when applying through certain municipal offices. After the ceremony, the officiant submits the signed marriage licence for registration; couples should wait approximately 6 to 8 weeks before applying for their official Marriage Certificate through ServiceOntario.
