The Parliament of Canada has exclusive legislative authority over marriage and divorce in Canada under section 91(26) of the Constitution Act, 1867. However, section 92(12) of the Constitution Act, 1867 gives the provincial legislatures the power to pass laws regulating the solemnization of marriage.

The marriage rate in Canada has been declining over the years. In 2001, there were 146,618 marriages in Canada, down 6.8% from 157,395 in 2000, but by 2020, there were only 98,355 marriages registered in Canada, which was the lowest total since 1938. Prince Edward Island had the highest crude marriage rate (6.5 per 1,000 people) and Quebec had the lowest (3.0).

Marriage ceremonies in Canada can be either civil or religious. Marriages may be performed by members of the clergy, marriage commissioners, judges, justices of the peace or clerks of the court, depending on the laws of each province and territory regulating marriage solemnization. In 2001, the majority of Canadian marriages (76.4%) were religious, with the remainder (23.6%) being performed by non-clergy.

Same-sex marriage has been legal in Canada nationally since 2005. Court decisions, starting in 2003, had already legalized same-sex marriage in eight out of ten provinces and one of three territories.

Restrictions Consanguinity The federal Marriage (Prohibited Degrees) Act, Section 2Marriage (Prohibited Degrees) Act, SC 1990, c. 46. prevents the following persons from getting married:

Subject to subsection (2), persons related by consanguinity, affinity or adoption are not prohibited from marrying each other by reason only of their relationship. No person shall marry another person if they are related lineally, or as brother or sister or half-brother or half-sister, including by adoption.

Consent of spouses Both parties must freely consent. Forcing somebody to get married is a criminal offence under s. 293.1 of the Criminal Code.Criminal Code, RSC 1985, c. C-46. In addition, s. 2.1 of the Civil Marriage Act stipulates, "Marriage requires the free and enlightened consent of two persons to be the spouse of each other."Civil Marriage Act, SC 2005, c. 33.

Age of spouses Since 2015, federal law has set the absolute minimum marriageable age at 16.Zero Tolerance for Barbaric Cultural Practices Act, SC 2015, c 29, http://canlii.ca/t/52m2q retrieved on 2018-06-24 Provinces and territories may set a minimum age higher than that. In Canada the age of majority is set by province/territory at 18 or 19, so persons under this age have additional restrictions (i.e. parental and court consent). Section 293.2 of the Criminal Code also addresses marriages of individuals under the age of 16, reading: Everyone who celebrates, aids or participates in a marriage rite or ceremony knowing that one of the persons being married is under the age of 16 years is guilty of an indictable offence and liable to imprisonment for a term not exceeding five years. Section 2.2 of the Civil Marriage Act also states: No person who is under the age of 16 years may contract marriage. These provisions were enacted in 2015. Before 2015, it was possible for children less than 16 years old to get married in some jurisdictions of Canada, with parental consent or a court order. (The legal marriage age with parental consent was possibly as low as 7 in some Canadian jurisdictions.)

Polygamy

In Canada, polygamy is a criminal offence, but prosecutions are rare. In March 2014, Winston Blackmore and James Oler were charged with polygamy; their prosecutions were the first such cases in Canada in over sixty-five years. In 2007, an independent prosecutor in British Columbia recommended that Canadian courts be asked to rule on the constitutionality of laws against polygamy. The Supreme Court of British Columbia upheld Canada's polygamy laws in a 2011 reference case.

On March 9, 2018, the Supreme Court of British Columbia reaffirmed the constitutionality of Canada's anti-polygamy laws, upholding the July 2017 polygamy convictions of Winston Blackmore and James Oler.
