On December 15, 2025, Canada introduced new citizenship rules that changed who could qualify as a Canadian citizen by descent.
The changes meant that many Americans with Canadian parents, grandparents, or earlier ancestors could have a path to Canadian citizenship. Some people who had never considered their family’s Canadian roots began looking for birth records and other documents to confirm their eligibility.
Bill C-3 amended Canada’s Citizenship Act by removing the first-generation limit, which had prevented many Canadians born abroad from passing citizenship to their children also born abroad. It also introduced a substantial connection requirement for children born abroad on or after December 15, 2025.
However, the law was not introduced overnight. It followed years of debate, a court challenge, and an earlier legislative attempt that did not become law.
How The First-Generation Limit Began?
Canada introduced the first-generation limit in 2009. Under this rule, Canadian citizens born outside Canada generally could not automatically pass their citizenship to children who were also born outside the country.
The policy followed concerns that arose after Canada evacuated thousands of citizens from Beirut during the 2006 conflict in Lebanon. Some of those citizens had lived in Lebanon for many years.
The situation led to public debate about people who held Canadian citizenship but lived mainly in other countries. Some commentators described them as ‘Canadians of convenience.’
The Conservative government introduced the first-generation limit to prevent Canadian citizenship from passing indefinitely through generations born abroad.
However, the rule later faced criticism because it treated some Canadian citizens differently based on where they were born.
Seven Families Challenged The Rule
In 2021, members of seven families challenged the first-generation limit in the Ontario Superior Court of Justice.
They argued that the rule unfairly treated people differently based on their place of birth and restricted their rights and ability to move freely. They also argued that the policy could disproportionately affect women who gave birth outside Canada because of work, education, medical needs, or a partner’s employment.
On December 19, 2023, Justice Jasmine Akbarali ruled that the limit was unconstitutional because it violated the Canadian Charter of Rights and Freedoms.
The court found that Canadians born in Canada had greater rights to pass citizenship to children born abroad than citizens who had acquired their citizenship through their parents.
The decision described the affected group as holding a ‘lesser class of citizenship’ because they could not pass their Canadian status to children born outside the country.
The court struck down the relevant provisions and gave the federal government time to change the law.
The Government Agreed But Faced Delays
In January 2024, the federal government announced that it would not appeal the court’s decision. The immigration minister at the time, Marc Miller, acknowledged that the rule had created unfair outcomes for Canadian families with children born abroad.
Parliament then needed to introduce legislation to replace the existing rule.
In May 2024, the government introduced Bill C-71, which aimed to restore citizenship to people affected by the first-generation limit.
While the bill moved through Parliament, Immigration, Refugees and Citizenship Canada (IRCC) introduced temporary measures to help certain applicants.
In June 2024, the department created an urgent route for a limited group seeking proof of citizenship. In March 2025, it announced broader interim measures that allowed some affected people to receive citizenship on a case-by-case basis.
Meanwhile, the government requested more time to meet the court’s deadline. It sought extensions in June and August 2024.
Political changes caused further delays. In January 2025, Justin Trudeau announced that he would resign as Liberal leader, and Parliament was prorogued. The federal government later confirmed that it would miss the court’s deadline, which had been extended to March 2025.
Bill C-3 Replaced The Earlier Proposal
On June 5, 2025, the government introduced Bill C-3 to address the issue. The legislation followed much of the same approach as the earlier Bill C-71 but included an important requirement for future generations.
Under the substantial connection test, a Canadian parent generally must have spent at least 1,095 days in Canada before their child’s birth or adoption to pass citizenship to a child born or adopted abroad under the new rules.
Parliament passed Bill C-3 on November 19, 2025, one day before the court’s final deadline. The new law came into effect on December 15, 2025.
The changes created a path to citizenship for many people who had previously been excluded by the first-generation limit.
Why Reversing Bill C-3 Would Be Difficult?
Bill C-3 went through several stages before becoming law. It had to pass first reading, second reading, committee review, report stage, and third reading in the House of Commons. It then had to complete the required stages in the Senate before receiving royal assent.
Reversing the legislation would require a similar parliamentary process. A future government would need to introduce a new bill and secure its passage through both chambers of Parliament.
Such a change would take time and would likely involve public and political debate.
Even if Parliament introduced new restrictions in the future, that would not automatically mean people who had already acquired Canadian citizenship would lose it. The effect of any future legislation would depend on its wording and how the law applied to existing citizens.
Bill C-3 was therefore the result of a long legal and political process, rather than a sudden decision to expand citizenship. It addressed a court ruling about unequal treatment while setting new conditions for passing citizenship to future generations born abroad.
