Does my ancestor need to have been born in Canada for me to qualify?

No. If your ancestor immigrated to Canada and became a naturalized citizen before their child (the next person in your chain) was born, that counts. The key requirement is that they were Canadian at the time of their child's birth.

How do I prove my ancestor was naturalized?

Naturalization records are held by Library and Archives Canada. You can search their database online or request records by mail. Records typically include the person's name, country of origin, date of naturalization, and sometimes their address and occupation.

What if my ancestor was naturalized after their child was born?

If your ancestor was not yet a Canadian citizen when their child was born, that child did not inherit Canadian citizenship at birth. However, you might still have a path if there is another Canadian ancestor in your family tree.

What about British subjects who lived in Canada before 1947?

Before 1947, people in Canada were British subjects, not Canadian citizens. If your ancestor was domiciled in Canada on January 1, 1947, they became a Canadian citizen automatically. See our guide on pre-1947 British subjects for details.

Canadian Citizenship Through a Naturalized Ancestor (Not Born in Canada)

Your ancestor does not need to have been born in Canada. If they immigrated and became a naturalized Canadian citizen before your parent was born, you may qualify under Bill C-3.

Many people assume you need a Canadian-born ancestor to claim citizenship by descent. That is not the case. If your ancestor immigrated to Canada and became a naturalized citizen, their descendants can qualify under Bill C-3 just like descendants of Canadian-born citizens.

How Naturalization Creates a Citizenship Chain

The rule is simple: your ancestor must have been a Canadian citizen at the time their child (the next generation in your chain) was born. It does not matter how they became Canadian.

Example: Your great-grandmother was born in Ukraine in 1895. She immigrated to Saskatchewan in 1912 and was naturalized as a Canadian citizen in 1920. Your grandmother was born in Saskatchewan in 1925. Your great-grandmother was Canadian when your grandmother was born, so the chain is valid.

If your great-grandmother had her child in 1918 (before her 1920 naturalization), the chain would be broken at that link, because she was not yet Canadian when the child was born.

Finding Naturalization Records

Library and Archives Canada

The primary source for Canadian naturalization records is Library and Archives Canada (LAC). Their collection includes:

1828-1850: Upper and Lower Canada naturalization records
1828-1929: Naturalization records from across Canada
1915-1951: Case files with detailed personal information

You can search their online database or request records by mail. Many records have been digitized and are available through their website at bac-lac.gc.ca.

Provincial Archives

Some provinces maintain their own naturalization records, particularly for earlier periods. Check the provincial archives for the province where your ancestor lived.

FamilySearch and Ancestry

Both FamilySearch.org (free) and Ancestry.ca (subscription) have indexed Canadian naturalization records that can help you locate your ancestor.

Common Naturalization Scenarios

European Immigrants (1880s-1950s)

Millions of Europeans immigrated to Canada during this period. Many settled in the Prairie provinces (Manitoba, Saskatchewan, Alberta) and became naturalized citizens. Common origins include Ukraine, Poland, Germany, Scandinavia, and the British Isles.

British Subjects Before 1947

People from anywhere in the British Empire could move to Canada freely. They did not need to "naturalize" in the modern sense because they were already British subjects. If they were domiciled in Canada on January 1, 1947, they became Canadian citizens automatically. See our guide on pre-1947 British subjects for more details.

Post-1947 Immigrants

After 1947, Canada had its own citizenship process. Immigrants who applied for and received Canadian citizenship through the formal process are naturalized citizens. Their children born afterward are Canadian by descent.

What You Need to Prove

Your ancestor was naturalized (or became Canadian through domicile on Jan 1, 1947)
The naturalization happened before the next generation was born (the timing is critical)
An unbroken chain of descent from that ancestor to you (same as any citizenship by descent claim)

Documents Required

Naturalization certificate or record for your ancestor (from Library and Archives Canada)
Birth certificate for each person in the chain
Marriage certificates where names changed
Your own birth certificate
CIT 0001 application form
