The US Supreme Court Just Settled It. Now Canada Needs to Act.

On June 30, 2026, the United States Supreme Court issued one of the most consequential rulings for women's sports in a generation. In a 6-3 decision, the Court ruled that schools may lawfully maintain women's and girls' sports categories for biological females. States may determine eligibility for female sports divisions based on biological sex. Title IX not only permits this, the Court found, it was always intended to protect it.

The ruling is unambiguous. "Sex" in Title IX means biological sex, as it did at the time of enactment in 1972. The physical differences between biological males and biological females are real, enduring, and directly relevant to athletic safety and competitive fairness.

The Court put it plainly: every biological male who wins a race takes that medal away from a female athlete. Every scholarship earned by a biological male in a women's division is a scholarship a girl trained years to compete for. These are not abstractions. They are the daily reality women's sports categories were created to address.

What the ruling confirmed

The Supreme Court affirmed several principles that women's advocates have been raising for years:

• Biological sex differences are real and relevant to athletic competition

• Protecting female sport divisions is a legitimate and substantial governmental interest

• No individual exemptions, hormone thresholds, or case-by-case assessments change the underlying biological reality

• Legislatures and policymakers, not courts, are the proper bodies to draw these rules

• 27 US states, the NCAA, World Athletics, and the International Olympic Committee had already drawn this same line before the Court did

The science and the policy were already converging. The Supreme Court simply confirmed it.

How Female Sport Was Opened to Males and What Is Being Done About It

The erosion of female sport categories did not happen overnight. It happened policy by policy, ruling by ruling, over more than two decades. Understanding how we got here is essential to understanding what needs to change.

Alberta Led the Way in Canada

Alberta is the only Canadian province to have protected female sports divisions by statute. At a time when the federal government was still describing the issue as complicated, Alberta acted. It watched what was happening internationally and did not wait for permission.

Alberta's legislative record

• October 31, 2024: Premier Danielle Smith introduced Bill 29, the Fairness and Safety in Sport Act, as part of a package of three bills addressing sex-based rights

• December 4, 2024: The Act received Royal Assent, making Alberta the first Canadian province to legislate biological sex as the basis for female sport divisions

• September 1, 2025: The Act and its supporting regulations came into force, requiring provincial sport organizations, school authorities, and post-secondary institutions to limit female-only divisions to biologically female athletes

• November 2025: Bill 9's notwithstanding clause was applied, shielding the sports legislation from Charter challenge on gender identity grounds

• May 2026: A federalism-based legal challenge to the legislation was denied, with an appeal pending

  
  

The regulations are specific. Organizations must verify athlete eligibility using birth records. The Act also requires the expansion or creation of open or mixed-sex divisions where numbers warrant, ensuring no athlete is left without a pathway to compete.

Alberta's approach reflects exactly what the US Supreme Court just confirmed at the federal level: clear, foreseeable, biology-based rules are both lawful and necessary. Bright-line rules exist precisely because case-by-case assessments cannot reliably protect a class of athletes.

No other Canadian province has matched Alberta's statute. No federal legislation exists. And the laws currently on the books at the national level actively complicate any attempt to protect female sport divisions.

Where Every Province Stands Right Now

Alberta is alone. Every other Canadian province leaves female sport eligibility to individual sport organizations, with no provincial statute, no standard, and no protection against human rights complaints for organizations that try to maintain biology-based criteria.

The Patchwork Problem: National Sport Organizations

Without a federal standard, Canada's national sport organizations have each gone their own direction. Some follow international biology-based policies. Others require only a hormone threshold that research shows does not eliminate male physiological advantage. Others still allow full self-identification with no criteria at all.

The result is that a female athlete's competitive protections in Canada depend entirely on which sport she plays and at what level. A swimmer is protected. A cyclist may not be. A university athlete in any sport may face male-bodied competitors in the women's category regardless of what their sport's national body has decided.

The Federal Legislation That Needs to Change

To achieve the kind of protection the US Supreme Court just affirmed at the federal level, Canada would need action on three specific pieces of federal law. Each has its own history, its own gap, and its own required fix.

Bill C-16: The Canadian Human Rights Act Amendment (2017)

What It Is

Bill C-16, An Act to amend the Canadian Human Rights Act and the Criminal Code, received Royal Assent on June 19, 2017. It added "gender identity or expression" to the list of prohibited grounds of discrimination under the Canadian Human Rights Act, placing it alongside sex, race, religion, and sexual orientation.

The History

Prior to 2017, sport organizations that maintained female-only categories based on biological sex were on firm legal ground. After 2017, they found themselves navigating a conflict between two protected characteristics: sex and gender identity. The Canadian Centre for Ethics in Sport responded in 2016, pre-empting the legislation, by recommending full inclusion of male-bodied athletes in female categories based on self-identification alone. Sport Canada never endorsed that guidance or made it a condition of funding, but national sport organizations were left to manage the legal ambiguity on their own.

The result has been inconsistency across sports and provinces. Some organizations require hormone therapy. Some require documentation. Some accept self-identification. Female athletes in the same country face different competitive landscapes depending on which sport they play and where they live.

The Physical Activity and Sport Act (2003)

What It Is

The Physical Activity and Sport Act is Canada's primary federal statute governing amateur sport. Passed in 2003, it established the framework under which Sport Canada funds national sport organizations, administers the Athlete Assistance Program, and sets conditions for sport participation in Canada.

The History

The Act does not define "female" or "male" anywhere in its text, and it has not been substantively amended since 2017. This means the Act predates Bill C-16's complications entirely and has never been updated to address the tension between sex and gender identity in sport eligibility.

Sport Canada's current position is that it does not have an official policy on transgender inclusion in sport and does not make adoption of any eligibility framework a condition of national sport organization funding. Organizations are "encouraged to find innovative, evidence-based solutions." That is not a policy. It is an abdication. The current 2025-26 Sport Support Program budget is $195 million, deployed with no requirement that funded organizations maintain any standard for female sport category eligibility.

The Sport Canada Funding Framework

What It Is

Sport Canada administers federal funding to national sport organizations through the Sport Support Program, the Athlete Assistance Program, and the Hosting Program. As of April 2025, national sport organizations must meet five governance requirements as a condition of funding, including athlete representation, dispute resolution, and adoption of the Canadian Safe Sport Program.

The History

Sport Canada has never added female sport eligibility to its conditions of funding. When Aquatics Canada voted in 2022 to adopt the World Aquatics policy restricting the female category to biological females, Sport Canada's own internal guidance noted there was "no basis for considering whether the provision of funding by Sport Canada to Aquatics Canada, or any NSO supporting a similar gender policy, engages CHRA concerns." In other words, Sport Canada acknowledged that biology-based policies are likely legal, and then did nothing.

The Legislative Journey: From the Gap to the Fix

The full arc from the federal statute that created the gap in 2003, through every milestone that has moved the needle, to the two Supreme Court rulings in 2025 and 2026 that have now confirmed biology-based eligibility is lawful.

The Bottom Line

The US Supreme Court just confirmed what women's advocates have been saying for years. Competitive fairness and athlete safety are legitimate and substantial governmental interests. Biology-based eligibility criteria for female sport divisions are lawful, necessary, and consistent with both the science and the original intent of sex-based sport categories.

Alberta read the room early and acted alone. Two Supreme Courts — in the United Kingdom in April 2025 and the United States in June 2026 — have now confirmed the same legal principle. Canada's Parliament has yet to respond.

Women and Girls Alberta will continue to advocate for the legislative changes Canadian female athletes need and deserve. Sport was built for women. It should stay that way.
