Bill C-23, titled the Modernization of Benefits and Obligations Act, was enacted in 2000. It granted same-sex couples who had been living together for over a year the same rights as heterosexual common-law couples under Canadian law.
(The legislation did not address same-sex marriage, and even included a definition of marriage that reaffirmed its traditional meaning as “the lawful union of one man and one woman to the exclusion of all others.”)
Steps Toward Equality
1969
The Criminal Law Amendment Act makes homosexuality legal by removing criminal penalties for sexual acts between consenting adults aged 21 and older, regardless of gender.
1977
Quebec amends its human rights code to make discrimination based on sexual orientation illegal. It is the first province to do so. Two years later, the Canadian Human Rights Commission suggests that the whole country add “sexual orientation” to its national human rights law.
1985
Section 15 is added to Canada’s Charter of Rights and Freedoms. It guarantees that:
Every individual is equal before and under the law and has the right to the equal protection and equal benefit of the law without discrimination and, in particular, without discrimination based on race, national or ethnic origin, colour, religion, sex, age or mental or physical disability.
Although sexual orientation isn’t explicitly mentioned, Section 15 goes on to be used as a source of LGBTQIA2S+ rights in Canada.
1993
In the case of Canada (Attorney General) v. Mossop, two Supreme Court judges found that “family status” could include same-sex couples cohabitating in a long-term relationship.
1995
Even though a same-sex couple loses their case about receiving spousal pension benefits (Egan v. Canada), the Supreme Court judges unanimously agree that sexual orientation falls within Section 15 of the Charter and should be protected—including same-sex relationships.
Around the same time, an Ontario judge rules that the province’s Child and Family Services Act violated the Charter rights of same-sex couples by not allowing them to adopt children together. Ontario becomes the first province to make adoption legal for same-sex couples.
1999
When two women in Toronto break up after living together for over a decade, one sues the other for spousal support under Ontario’s Family Law Act (M. v. H.). The Supreme Court rules that the Act’s definition of “spouse”—limited to married couples or common-law opposite-sex pairs—is unconstitutional.
Rather than redefining “spouse,” the Ontario government introduces Bill 5 in October 1999, creating a separate “same-sex partner” category and changing the Family Law Act to read “spouse or same-sex partner” throughout.
2000
Parliament passes Bill C-23.
2005
The Civil Marriage Act becomes law on July 20, legalizing same-sex marriage across Canada.
Total Statutes Amended by Bill C-23: 68
These changes affected approximately 20 federal departments and agencies, making the Modernization of Benefits and Obligations Act one of the most sweeping pieces of equality-focused legislation in Canadian history. The amendments enhanced several important aspects of same-sex couples’ lives.
1. Modern Relationships
Added the term “common-law partner” to offer legal recognition for the relationships between same-sex couples. This impacted a number of acts, including:
- The Canada Elections Act
- The Citizenship Act
- The Cree-Naskapi (Of Quebec) Act
2. Financial Equity
The legal amendments of Bill C-23 transformed financial planning for same-sex couples in committed relationships, giving them a more solid legal standing when it came to managing money together. Several important acts were revised, such as:
- The Bank Act
- The Bankruptcy and Insolvency Act
- The Income Tax Act
3. Insurance Coverage
The Modernization of Benefits and Obligations Act revolutionized the accessibility of insurance benefits and coverage for same-sex partners. Amendments were made to a number of acts, including the following:
- The Civil Service Insurance Act
- The Insurance Companies Act
- The Veterans Insurance Act
4. Family Support
Amendments were made to establish comprehensive family support frameworks that recognized the mutual responsibilities and protections inherent in all committed relationships. This affected laws such as:
- The Criminal Code
- The Employment Insurance Act
- The Old Age Security Act
5. Pension
The amendments from Bill C-23 fundamentally transformed pension rights by extending comprehensive retirement protections to common-law partners, ensuring access to survivor benefits and pension security. A number of laws were revised, including:
- The Canada Pension Plan
- The Canadian Forces Superannuation Act
- The Members of Parliament Retiring Allowances Act
Did You Know?
When Statistics Canada first counted same-sex couples in 2001, they found about 0.5 percent of all Canadian couples were same-sex—officially recognizing a community that had been statistically invisible until then.
