For many families in the United States, a Canadian connection may be much closer than they realize. A parent, grandparent or earlier ancestor may have been born or lived in Canada before the family eventually moved south.

A major change to Canada’s citizenship law has made these family connections more important.

On December 15, 2025, Bill C-3 came into effect, changing Canada’s rules around citizenship by descent and removing the previous first-generation limit in certain circumstances. The changes also address some people previously excluded under older citizenship rules.

What Is Citizenship by Descent?

Canadian citizenship by descent generally refers to citizenship acquired through a Canadian parent rather than through immigration or naturalization.

Under the previous rules, citizenship passed to people born outside Canada was generally restricted by a first-generation limit. This created situations where Canadian families living abroad could not pass citizenship to children born outside Canada.

Bill C-3 changed this framework.

For people born outside Canada before December 15, 2025, the new law can restore or recognize citizenship where the person would have been Canadian but for the former first-generation restriction or certain outdated provisions.

Could Your Family History Matter?

You may want to investigate your family history if you have a Canadian-born parent or another documented Canadian connection.

Families with roots in Quebec, Ontario and other parts of Canada may discover Canadian connections that have been forgotten over several generations. Surnames can also change over time through marriage, translation or other family circumstances, meaning a person’s current surname may not reveal their Canadian ancestry.

However, simply having a Canadian-sounding surname or believing that an ancestor was Canadian is not enough by itself.

The key is establishing the family relationship through reliable documents.

What Documents May Be Needed?

A proof of Canadian citizenship application normally requires evidence establishing the applicant’s connection to Canada.

Depending on the circumstances, records may include:

  • Birth certificates
  • Marriage certificates
  • Adoption records
  • Baptismal records
  • Death certificates
  • Historical immigration or naturalization records
  • Other government or civil records connecting each generation

The objective is to establish the family chain from the applicant to the relevant Canadian parent or ancestor.

IRCC provides an official process for people who believe they may already be Canadian to obtain a Canadian citizenship certificate as proof of status.

What About Future Generations?

Bill C-3 also introduced a new framework for certain future cases.

Where a Canadian parent was themselves born or adopted outside Canada, the parent may need to demonstrate a substantial connection to Canada before passing citizenship to a child born or adopted abroad. IRCC describes this connection as at least 1,095 cumulative daysthree years of physical presence in Canada before the child’s birth or adoption.

This means the new rules are more flexible than the old first-generation system, but they are not an unlimited automatic citizenship rule for everyone with a distant Canadian ancestor.

Why This Could Be Important for Americans

For Americans with Canadian family roots, determining whether they already have Canadian citizenship can be valuable.

If you qualify, you may not need to immigrate through Express Entry, a Provincial Nominee Program (PNP) or another permanent residence pathway simply to become Canadian. Instead, the issue may be documenting citizenship that you already possess under Canadian law.

Before making assumptions, however, it is important to have your family history and documents properly reviewed.
