The Persons Case: When Women Became "Persons" Under Canadian Law

Today, it is difficult to imagine a qualified Canadian being excluded from one of the country's highest public offices simply because of their sex.

Yet less than one hundred years ago, women could not be appointed to the Senate of Canada.

The legal barrier was not created by a law that explicitly excluded women. Instead, it arose from how a single word in Canada's Constitution had been interpreted for decades. That word was "Persons." [1]

What followed became one of the most important constitutional cases in Canadian history. Known today as the Persons Case, the dispute helped open the Senate to women and established a constitutional principle that continues to influence Canadian courts nearly a century later. [3]

The decision is often remembered as a milestone in the advancement of women's rights. Equally important, however, is the way the case changed how Canada's Constitution is interpreted. The legal reasoning developed in the Persons Case continues to appear in constitutional decisions today, making it one of the most influential cases ever decided in Canada. [3]

Canada Before the Persons Case

To understand why the case mattered, it helps to remember what Canada looked like in the early twentieth century.

Women had already achieved significant legal and political gains. Several provinces had extended voting rights to women, and by 1918 many Canadian women could vote in federal elections. Women were increasingly involved in education, business, social reform movements, and public life. [5][6]

Despite these advances, important barriers remained. One such barrier involved the Senate of Canada.

Section 24 of the British North America Act, 1867, now known as the Constitution Act, 1867, provides that qualified "Persons" may be summoned to the Senate. [1]

For decades, governments interpreted the word "Persons" as applying only to men. As a result, women could participate in many aspects of public life yet remained ineligible for appointment to Canada's upper chamber. [4][5]

By the 1920s, many Canadians viewed that interpretation as increasingly outdated.

Five women (Emily Murphy, Nellie McClung, Henrietta Muir Edwards, Louise McKinney, and Irene Parlby) in dark coats stand on courthouse steps before signs reading Women Are Persons and Victory for Women, Canadian flag.

The Famous Five

The challenge to this interpretation was led by five Alberta women who became known as the Famous Five:

• Emily Murphy

• Henrietta Muir Edwards

• Nellie McClung

• Louise McKinney

• Irene Parlby [4][5]

Each woman had established herself as a prominent advocate for social and political reform.

Emily Murphy, for example, had become Canada's first female police magistrate. During her work in the justice system, questions arose regarding whether women were legally eligible to hold certain public offices. [4][5]

These questions helped spark a broader discussion about women's place within Canada's constitutional framework.

In 1927, the Famous Five petitioned the federal government to refer a constitutional question to the Supreme Court of Canada. [4]

The question was straightforward:

"Does the word 'Persons' in section 24 of the British North America Act, 1867, include female persons?" [2]

Although simple in wording, the answer would have significant consequences.

The Supreme Court of Canada Says No

In 1928, the Supreme Court of Canada considered the question. [2] The Court concluded that women were not included within the meaning of "Persons" for the purpose of Senate appointments. [2] The reasoning largely reflected historical assumptions existing at the time Confederation was created in 1867.

The judges examined the legal and political environment of the nineteenth century and concluded that the framers of the Constitution likely did not intend women to serve in the Senate. [2]

As a result, the Court answered the question in the negative.

Today, the decision often surprises readers. Many assume that because women had already gained voting rights, eligibility for Senate appointments would naturally follow.

The Supreme Court's ruling demonstrated that legal progress often occurs unevenly. Expanding rights in one area does not automatically remove barriers in another.

The Famous Five refused to accept the decision and pursued a further appeal. [4][5]

The Final Appeal to London

At the time, Canada's highest court was not the Supreme Court of Canada. The final court of appeal for many Canadian matters was the Judicial Committee of the Privy Council in London, England. [3]

The Famous Five appealed the Supreme Court's decision to the Privy Council.

The appeal would ultimately transform Canadian constitutional law. On October 18, 1929, the Privy Council overturned the Supreme Court's ruling. [3]

The decision was written by Lord Sankey. T ne of the most frequently cited passages stated:

"The exclusion of women from all public offices is a relic of days more barbarous than ours." [3]

The statement reflected the Court's view that legal interpretation should not remain tied indefinitely to outdated social assumptions.

The Privy Council concluded that women were indeed "Persons" within the meaning of section 24 and therefore eligible for appointment to the Senate. [3]

The decision immediately removed the constitutional barrier that had prevented women from serving in Canada's upper chamber.

The Birth of the Living Tree Doctrine

The Persons Case is often remembered for its impact on women's participation in public life.

Lawyers and judges, however, frequently focus on another aspect of the decision. In explaining why the Constitution should not be interpreted narrowly, Lord Sankey described Canada's Constitution as:

"a living tree capable of growth and expansion within its natural limits." [3]

Those words became one of the most important constitutional principles in Canadian history. The "living tree" doctrine recognizes that constitutions are intended to endure for generations. Society changes. Technology changes. Governments change.

A constitution written in one era must remain capable of functioning in another. The doctrine does not permit courts to rewrite the Constitution whenever they wish. Rather, it acknowledges that constitutional language should be interpreted in a way that allows it to remain meaningful as society evolves. [3]

Nearly a century later, Canadian courts continue to rely on this principle.

Why the Persons Case Still Matters

The legal significance of the Persons Case extends far beyond Senate appointments. The decision helped shape the modern approach to constitutional interpretation in Canada. [3][5]

Whenever courts consider how constitutional provisions apply to issues that could not have been anticipated by earlier generations, they are often applying principles that can be traced back to the Persons Case. [3]

The case also serves as a reminder that constitutional disputes often involve more than technical legal questions. The original issue concerned a single word. Yet that word affected who could participate in one of Canada's most important democratic institutions. Many landmark legal decisions begin in a similar way. What appears to be a narrow legal question can have far-reaching consequences.

Common Misconceptions About the Persons Case

The Persons Case is frequently misunderstood.

One common misconception is that women were not considered legal persons before 1929.

That is not accurate.

Women could own property, enter contracts, commence legal proceedings, inherit assets, and exercise numerous legal rights long before the case was decided. [5]

The issue before the courts was far narrower. The question was whether women were included within the meaning of "Persons" in a specific constitutional provision dealing with Senate appointments. [2][3]

Another misconception is that the decision instantly created equality between men and women.

It did not.

Many barriers remained. The Persons Case represented an important milestone, but it was only one chapter in a much broader history of legal, political, and social change. [5][6]

Historical Recognition and Modern Discussion

The Famous Five occupy a prominent place in Canadian history. Statues commemorating the group stand on Parliament Hill in Ottawa and in Calgary's Olympic Plaza. [4][5] The case is routinely taught in schools, discussed in constitutional law courses, and referenced in public conversations about equality and constitutional rights.

At the same time, modern discussions have become more nuanced. Historians have noted that some members of the Famous Five supported positions that are viewed critically today, including support for eugenics policies. [5]

As a result, contemporary discussions often seek to acknowledge both the importance of the legal achievement and the broader historical context surrounding the individuals involved.

A Legacy That Continues

Nearly one hundred years after the decision was released, the Persons Case remains one of the most influential constitutional decisions in Canadian history. [3][5]

Its legacy can be found not only in the Senate chambers that women were eventually permitted to enter, but also in courtrooms across the country where judges continue to interpret the Constitution as a living document. [3]

The question posed by the Famous Five in 1927 appeared deceptively simple. Yet the answer reshaped Canadian constitutional law and helped define how future generations would understand equality, citizenship, and constitutional interpretation. What began as a challenge to a long-standing legal assumption ultimately became one of the most important constitutional decisions in Canadian history.
