Who lost citizenship under the 1947-1977 oath requirement?
Short answer: The 1947 Canadian Citizenship Act required certain people, most notably British subjects living in Canada or abroad, to take an oath of citizenship by age 24 or lose any claim to Canadian citizenship. Many people abroad never knew about the requirement and were stripped by inaction. Bill C-37 (2009) restored citizenship to anyone affected by this rule.
If your grandparent was born in Canada or a British colony, lived part of their early life in Canada or in another British dominion, and then moved abroad without formally taking the Canadian oath before age 24, they may have lost their Canadian citizenship under the 1947 Act. Their descendants would have inherited only U.S. (or other) citizenship.
Bill C-37 retroactively restored citizenship in these cases. Your grandparent is treated as a Canadian citizen from 1947 onward, and citizenship descends through them under the modern rules (subject to Bill C-3's FGL removal).
This category is less common in U.S. genealogies but still exists. The 1947 rule mostly affected Britons, Australians, and others who moved through the Commonwealth without formalizing Canadian citizenship.
Who was affected by the section 8 forced renunciation rule (1977-2009)?
Short answer: Section 8 of the 1977 Citizenship Act required second-generation-born-abroad Canadians (people born outside Canada whose Canadian-citizen parent was also born outside Canada) to apply to retain their Canadian citizenship by age 28, or lose it automatically. Many people had no idea this rule existed and never applied. The provision was repealed in 2009 by Bill C-37, but the damage to many people's citizenship was already done. Bill C-37 retroactively restored citizenship to most affected people.
Section 8 was a particularly cruel provision:
- It applied only to second-generation-born-abroad Canadians (i.e., your parent was a Canadian born abroad, you were also born abroad).
- It required an affirmative application to retain citizenship between ages 23 and 28.
- If you missed the deadline, your citizenship was automatically extinguished, with no notice or appeal.
- The provision was in force for 32 years (1977-2009).
Bill C-37 repealed section 8 and retroactively restored citizenship to those who had lost it. For most affected people, the restoration is automatic, making them Canadian citizens by operation of law; the proof-of-citizenship application (Form CIT 0001) is the only paperwork needed.
If you had been told by IRCC any time between 1977 and 2009 that you "lost" your Canadian citizenship under section 8, you are now a citizen again. The restoration is law-of-the-land, not a discretionary grant.
What was the First-Generation Limit and who does Bill C-3 help (2009-2025)?
Short answer: From April 17, 2009 to December 15, 2025, Canada's Citizenship Act limited citizenship by descent to the first generation born abroad. If your Canadian-citizen parent was born outside Canada and you were also born outside Canada, you did NOT inherit citizenship, even if your grandparents and earlier ancestors were Canadian. Bill C-3 retroactively removes this limit.
The First-Generation Limit was the most recent and broadest Lost Canadian category. It affected:
- Children of Canadian diplomats and military serving abroad
- Children of Canadians working abroad in international organizations or multinationals
- Descendants of Canadian immigrants to the U.S., U.K., Australia, and elsewhere who were second-generation or further
The 2023 Ontario court ruling in Bjorkquist v. Canada held the FGL unconstitutional. Bill C-3 codified the ruling and went further, explicitly retroactive to anyone born before December 15, 2025, as detailed on IRCC's 2025 citizenship rules page.
If you were excluded from Canadian citizenship by the FGL between 2009 and 2025, you are now a citizen retroactively. The path to your certificate is the same Form CIT 0001.
How do you claim restored Canadian citizenship?
Short answer: There is NO separate restoration application. You file Form CIT 0001 (Application for a Citizenship Certificate) just like any other proof-of-citizenship applicant. The form asks why you are applying. Select "Born outside Canada to a Canadian citizen parent" or the appropriate option. IRCC will process the application against the current law (with Bill C-3's retroactive operation), and the resulting certificate proves you are a citizen.
The mechanical process is identical to the Bill C-3 by-descent process described in our Proof of Canadian Citizenship Application step-by-step guide:
- Run IRCC's free Am I a Canadian citizen tool to confirm eligibility.
- Gather genealogy documents: long-form birth certificates and marriage certificates for every generation in your line.
- Complete Form CIT 0001 and CIT 0014 (document checklist).
- Pay the $75 CAD fee online.
- Submit online or by mail to Sydney, NS.
- Wait ~11 months for the certificate.
The unique aspect for Lost Canadians is the historical documentation. If your line crosses a pre-1947 marriage where citizenship was deemed lost, you may need additional records (the original marriage certificate, the wife's maiden-name birth certificate, possibly a death certificate). If your line crosses a section 8 case from 1977-2009, there is nothing additional needed beyond the standard genealogy chain, as Bill C-37 handles it automatically.
For pre-1947 cases with limited documentation, statutory declarations from family members can substitute for missing records, but the application typically takes longer and may require a Letter of Request for Information from IRCC.
What are the most common Lost Canadian scenarios?
Short answer: The five most common Lost Canadian scenarios we encounter at Go Far Global are: (1) U.S. resident with a Canadian grandmother who married an American before 1947; (2) U.S. resident with a Canadian-born grandparent who naturalized in the U.S. before 1977 without formally renouncing Canadian citizenship; (3) U.S. resident whose parent was born abroad to Canadian-citizen grandparents and was excluded by the FGL; (4) Person previously notified of "loss" of citizenship under section 8 between 1977 and 2009; (5) Children of pre-1947 Canadian war brides who emigrated to other countries.
Scenario 1: U.S. resident with pre-1947 Canadian grandmother
Marie was born in Trois-Rivières, Quebec, in 1918. She married American serviceman John in 1942 and moved to Pittsburgh. Their son Robert was born in 1945. Robert had a daughter Sarah in 1972. Sarah has a son David in 2003.
Pre-Bill C-3: David is not Canadian. Marie was deemed to have lost her status; the line was broken.
Post-Bill C-3: Marie is treated as a Canadian citizen throughout. Robert, Sarah, and David are all Canadian citizens by descent. Each can apply for proof of citizenship.
Scenario 2: Grandparent naturalized in U.S. before 1977
Jean was born in Manitoba in 1925. He moved to Minnesota in 1948 and became a U.S. citizen in 1958. He never formally renounced Canadian citizenship (renunciation required a separate process; merely naturalizing in another country did not automatically renounce). His daughter Anne was born in Minnesota in 1955. Anne's son Mark was born in 1985.
Pre-Bill C-3: Mark was excluded by the FGL, as Anne was already second-generation and Mark was third-generation.
Post-Bill C-3: Mark is a Canadian citizen by descent through Jean (great-grandfather Canadian-born) → Anne (Canadian by descent under retroactive Bill C-3) → Mark.
Scenario 3: Parent born abroad to Canadian-citizen parents
David's father Tom was born in California in 1965 to two Canadian parents who had moved south for work. Tom was a Canadian citizen by descent (first generation born abroad). David was born in Texas in 1988.
Pre-Bill C-3: David was excluded by the FGL.
Post-Bill C-3: David is a Canadian citizen. Tom's Canadian status is intact, and Bill C-3 removes the cap. David qualifies through CIT 0001.
Scenario 4: Previous section 8 "loss" notice
Sarah's parents were both born outside Canada to Canadian-citizen parents. Sarah was born in 1962. Section 8 of the 1977 Citizenship Act required her to apply to retain Canadian citizenship before age 28 (i.e., by 1990). She didn't apply. In 1991, IRCC sent her a letter informing her that her Canadian citizenship had been extinguished.
Bill C-37 (2009) repealed section 8 and retroactively restored citizenship to people like Sarah. Sarah is a Canadian citizen now. The 1991 IRCC letter is obsolete; she can apply for proof of citizenship and will be issued a certificate.
Scenario 5: War bride descendants
Many Canadian women who married Allied servicemen during WWII moved to other countries after the war. Some of these "war brides" formally renounced their Canadian citizenship under the 1947 Act and earlier statutes; others lost it by marriage. Bill C-3's retroactive operation, combined with Bill C-37 and Bill C-71's earlier work, restores citizenship to most war-bride descendants.
If your great-grandmother was a Canadian war bride, run the IRCC eligibility tool. There is a very high likelihood her line qualifies.
