Canada’s updated citizenship rules began on December 15, removing long-standing limits that had prevented many “Lost Canadians” from gaining citizenship.
Canada has officially changed its citizenship laws. The federal government brought the new rules into force on December 15. The changes aim to fix long-standing gaps that prevented some people from gaining citizenship. These individuals became known as “Lost Canadians” because the law denied them status despite strong family ties.
The changes come under Bill C-3, which became law last month. The updated rules now allow citizenship to pass down beyond the first generation in some cases. This marks a major shift in how Canada recognizes families who live or grow abroad.
What the New Rules Allow
Under the new law, people born or adopted outside Canada may now receive citizenship through their parents. This applies even when the Canadian parent was also born or adopted abroad. To qualify, the parent must show a strong connection to Canada. That connection requires at least three years of living in Canada before the child’s birth or adoption.
Children born outside Canada before December 15 now gain citizenship automatically if they belong to the second generation or later. Children adopted abroad before that date may apply for citizenship under the new rules. Officials will review these applications using the updated law.
The law also allows people who receive automatic citizenship to refuse it. The government says they can do so through a simplified process.
Minister Says Law Reflects Modern Families
Immigration Minister Lena Diab said the changes better reflect how Canadians live today. Many families move, work, or study outside the country. She said the new rules protect the citizenship rights of their children.
“These changes reflect how Canadian families live today,” Diab said. She added that Canadians should not lose the ability to pass on citizenship simply because of global mobility.
How the Problem Began
The issue began in 2009. The government at that time changed the Citizenship Act. The change limited citizenship by descent to the first generation born abroad. That meant children born outside Canada could not pass citizenship to their own children unless they were born or adopted in Canada.
This rule left many people without status. They had Canadian parents and grandparents but could not become citizens themselves.
In December 2023, the Ontario Superior Court ruled the limit unconstitutional. The court said the law created unequal classes of citizens. The federal government accepted the ruling and chose not to appeal.
Interim Measures and Applications
After the court decision, the government introduced temporary measures. These allowed affected people to apply for special citizenship grants. Immigration officials reviewed those cases while lawmakers worked on permanent changes.
Officials say people who already applied under those measures do not need to apply again. The department will continue reviewing those files under the new law.
Concerns Still Raised
Some concerns remain, especially around intercountry adoption. Senator David Arnot said the law treats adopted children unfairly. He pointed to the three-year Canada connection rule. He argued it should not apply to children adopted and raised in Canada.
Immigration lawyer Sujit Choudhry also raised concerns. He represents parents of intercountry adoptees. He said the law creates unequal treatment. “It’s already not easy to be adopted from halfway around the world,” he said. He added that families may still challenge the law in court.
Political Debate Continues
Opposition members raised cost concerns during debate. A budget report estimated the changes could affect more than 100,000 people over five years. Lawmakers ultimately passed the bill without further changes.
For many families, the law brings long-awaited recognition. For others, debate continues.
