Bill C-3: Millions of Americans Are Already Canadian Citizens — And Most Don’t Know What That Means Financially

Something quietly historic happened on December 15, 2025.
Canada passed Bill C-3 — formally titled An Act to Amend the Citizenship Act — and in doing so created what may be the largest single expansion of dual citizenship eligibility in modern history. Millions of Americans are now automatically Canadian citizens under the new law, with many filing for Proof of Citizenship as a contingency plan. Most of them have no idea what that means for their finances.
This post covers both sides of the Bill C-3 story: what the law actually does, and the financial obligations that come with it that almost nobody is explaining.

What Bill C-3 Actually Does
Before December 15, 2025, Canadian citizenship by descent was limited to the first generation born outside Canada. If your parent was born in Canada but you were born in the United States, you could claim Canadian citizenship. If your grandparent was born in Canada but your parent was born in the US, you generally could not — regardless of how strong your family connection to Canada was.
In December 2023, the Ontario Superior Court of Justice ruled that this first-generation limit was unconstitutional. The Government of Canada did not appeal the decision. On June 5, 2025, the government introduced Bill C-3 as a remedy, and it received Royal Assent on November 20, 2025. It came into effect on December 15, 2025.
| THE CORE CHANGE
For people born before December 15, 2025: Canada now imposes no generational cap on citizenship by descent. If you have any direct Canadian ancestor — a grandparent, great-grandparent, or more distant relative — and the chain of Canadian citizenship has not been formally severed, you may already be a Canadian citizen. The certificate process confirms what is legally already true. For people born on or after December 15, 2025: a substantial-connection test applies, requiring the Canadian parent to have accumulated 1,095 days of physical presence in Canada before the child’s birth.

The Word ‘Already’ Matters
This is not an application for new citizenship status. For many Americans, citizenship existed retroactively the moment the law took effect on December 15, 2025. The Proof of Citizenship certificate process with Immigration, Refugees and Citizenship Canada (IRCC) confirms what is already legally true under the new framework — it does not create the status, it documents it.
This distinction matters because it affects how you think about timing. You do not need to decide whether to ‘become’ a Canadian citizen. You need to determine whether you already are one.
The Numbers Behind the Surge
The interest from Americans has been significant and measurable. Vital records archives across Canada — Quebec, New Brunswick, British Columbia, Newfoundland, and Ontario — have all reported dramatic increases in requests from Americans tracing family lines to establish their descent chain.
Requests for certified copies of vital records at the Bibliothèque et Archives nationales du Québec jumped from 32 in January 2025 to over 1,000 in January 2026 — a 3,000 percent increase, with most of those requests made by Americans. As of early March 2026, nearly 48,000 people were waiting for decisions on citizenship certificate applications with an estimated processing time of 11 months.
One regulated Canadian immigration consultant described the citizenship certificate as ‘the hottest ticket in 2026.’ The processing time alone tells you the scale of demand.
| WHY AMERICANS WITH FRENCH-CANADIAN ANCESTRY ARE ESPECIALLY AFFECTED
The late 1800s and early 1900s saw heavy migration from Quebec to New England. Millions of descendants in the northeastern United States — Massachusetts, Connecticut, Rhode Island, Vermont, New Hampshire, and Maine — may have a valid descent claim through a Canadian grandparent or great-grandparent who emigrated during that period. An estimated 10 million Americans with historical roots in Quebec may now qualify for automatic Canadian citizenship under Bill C-3. Source: visaverge.com and CBC News. |
The Financial Implications Nobody Is Explaining
Here is the part of the Bill C-3 story that is missing from almost every article being written right now.
Becoming a dual US-Canadian citizen does not just give you a second passport. It creates a set of financial obligations that begin the moment your citizenship is recognized — and that most Americans are completely unprepared for.
- FBAR — Foreign Bank Account Reporting
Every US citizen who holds foreign financial accounts with a combined value exceeding USD $10,000 at any point during the year must file an FBAR (FinCEN 114) annually with the US Treasury. This covers Canadian chequing accounts, savings accounts, RRSPs, TFSAs, and investment accounts.
If you become a recognized Canadian citizen and open Canadian financial accounts — which most people do — you have an FBAR filing obligation. This applies regardless of whether you live in Canada or remain entirely in the United States. The filing deadline is April 15 with an automatic extension to October 15. Penalties for non-filing start at $10,000 per violation. FBAR is filed separately from your US tax return at fincen.gov.
- FATCA — Form 8938
FATCA requires US citizens with foreign financial assets above certain thresholds to file Form 8938 with their US tax return. For single filers living abroad the threshold is $200,000 on the last day of the year or $300,000 at any point during the year. Your Canadian accounts, property, and registered accounts may collectively trigger this requirement even if you remain based in the United States.
- The TFSA Trap
The Tax-Free Savings Account is one of Canada’s most popular investment vehicles. For Canadians, growth inside a TFSA is completely tax-sheltered. For Americans, it is a compliance problem.
The IRS treats a TFSA as a foreign grantor trust. Growth inside the account is taxable in the United States every year regardless of the Canadian tax treatment. Opening a TFSA as a newly recognized dual citizen without understanding this creates an annual US tax liability and additional reporting requirements. The administrative cost and tax drag make a TFSA an inefficient choice for most Americans in Canada.
| THE BETTER VEHICLE: RRSP
The Registered Retirement Savings Plan is recognized under the Canada-US Income Tax Convention. For Americans with Canadian financial interests, the RRSP is generally a significantly more efficient vehicle than the TFSA. The treaty election needs to be made correctly at setup, but the structure is sound and the IRS recognises the tax deferral. Discuss RRSP eligibility and the correct treaty election with a cross-border advisor before opening accounts. Source: Canada-US Income Tax Convention, canada.ca. |
- You Still File Two Tax Returns Every Year
The United States taxes citizens on worldwide income regardless of where they live. This has always been true and Bill C-3 does not change it. But it is relevant here because many Americans claiming Canadian citizenship are doing so with an eye toward eventually spending more time in Canada.
If and when that happens, they will file two tax returns annually — a US federal return (Form 1040) and a Canadian T1. The Canada-US tax treaty coordinates the two systems and prevents most double taxation through the Foreign Tax Credit mechanism. But the filing obligations on both sides remain active for as long as you hold US citizenship.
What Bill C-3 Does NOT Do
This is equally important to understand.
- It does not make you a Canadian tax resident — Canadian tax residency is determined by residential ties — where you live, where your family is, where your home is. An American who claims Canadian citizenship but continues to live entirely in the United States does not become a Canadian tax resident simply by holding a Canadian passport. The financial implications described above are primarily relevant when a dual citizen begins holding Canadian financial accounts or spending significant time in Canada.
- It does not pass citizenship automatically to your children born after December 15, 2025 — For children born on or after the law’s effective date, the substantial-connection test applies. Your Canadian parent must have accumulated 1,095 cumulative days of physical presence in Canada at any time before the child’s birth. Those days do not need to be consecutive.
- It does not eliminate US tax obligations — Becoming a Canadian citizen while remaining a US citizen does not reduce your US tax obligations in any way. You remain subject to worldwide income taxation, FBAR, FATCA, and all other US citizen tax requirements regardless of your Canadian status.
- It does not grant indefinite right to stay in Canada — Canadian citizenship grants the right to live and work in Canada without any time limit. But if you are not yet a recognized citizen — if you are still in the certificate application process — your right to stay in Canada remains governed by your immigration status. Do not assume you have the right to remain in Canada indefinitely while your application is pending.
The Correct Order of Operations
If you believe you may be eligible for Canadian citizenship under Bill C-3, the correct sequence matters significantly.
- Confirm eligibility with a qualified professional first.
Work with an immigration lawyer or regulated Canadian immigration consultant who understands the Bill C-3 descent rules. The chain of citizenship matters — how it passes through each generation and whether it was ever formally severed or renounced along the way. Do not assume eligibility without professional verification.
- Speak with a cross-border financial advisor before applying.
Before filing the citizenship certificate application, understand what the recognized citizenship will mean for your financial accounts, your FBAR obligations, and how to structure any Canadian accounts you open correctly from the start. Many of these decisions are significantly harder to undo after the fact than to structure correctly from day one.
- Apply for the citizenship certificate through IRCC.
Apply at canada.ca/en/immigration-refugees-citizenship. Current processing time is approximately 11 months. Gather your descent documentation — birth certificates, marriage certificates, and any Canadian records establishing the family chain — before filing to avoid delays.
- Apply for a Canadian passport once the certificate is issued.
The citizenship certificate is proof of status. A Canadian passport is the travel document. You need the certificate before you can apply for the passport. A Canadian passport currently allows visa-free travel to over 180 countries and has ranked higher than the US passport on the Henley Passport Index since 2025.
| IRCC PROCESSING REALITY
Archives across Canada have warned that the surge in requests is creating significant delays for vital records — a prerequisite for most citizenship certificate applications. The BAnQ in Quebec noted that priority is given to Quebec residents, and international applicants should expect extended timelines. Begin gathering historical family documents as early as possible, before the certificate application is filed. Source: CBC News, March 2026. |

| FREQUENTLY ASKED QUESTIONS |
| What is Bill C-3 and when did it take effect?
Bill C-3, formally titled An Act to Amend the Citizenship Act (2025), received Royal Assent on November 20, 2025, and came into effect on December 15, 2025. It removed the first-generation limit on Canadian citizenship by descent for people born before that date, retroactively restoring citizenship eligibility to descendants of Canadians who were previously cut off by the generational limit. |
| Can Americans with Canadian grandparents or great-grandparents claim citizenship under Bill C-3?
Potentially yes — for people born before December 15, 2025. If you have a direct Canadian ancestor and the chain of Canadian citizenship has not been formally severed along the way, you may already be a Canadian citizen under the new law. Eligibility must be confirmed by a qualified immigration lawyer or regulated Canadian immigration consultant who can review your specific family chain. |
| Does claiming Canadian citizenship under Bill C-3 create US tax obligations?
Claiming Canadian citizenship does not change your existing US tax obligations — you already owe them as a US citizen. However, if you open Canadian financial accounts after receiving citizenship, you will have FBAR (FinCEN 114) filing obligations for accounts exceeding USD $10,000, and potentially FATCA Form 8938 reporting requirements. |
| Is a TFSA a good account for Americans who become Canadian citizens under Bill C-3?
Generally no. The IRS treats a Tax-Free Savings Account as a foreign grantor trust, meaning growth inside a TFSA is taxable in the United States every year regardless of its tax-sheltered status in Canada. For Americans with Canadian citizenship interests, an RRSP — which is recognized under the Canada-US Income Tax Convention — is generally a more efficient vehicle. |
| What is the processing time for a Canadian citizenship certificate application in 2026?
As of early 2026, IRCC estimated processing times of approximately 11 months for citizenship certificate applications, reflecting a significant surge in applications following Bill C-3. Nearly 48,000 people were waiting for decisions as of March 2026. |
| Does becoming a Canadian citizen make an American a Canadian tax resident?
No. Canadian tax residency is determined by residential ties — where you live, where your family is, where your primary home is. An American who claims Canadian citizenship but continues to live entirely in the United States does not become a Canadian tax resident simply by holding a Canadian passport. Canadian tax residency obligations arise when you establish residential ties in Canada. |
| What is the substantial-connection test for children born after December 15, 2025?
For children born on or after December 15, 2025, a Canadian parent born abroad must demonstrate a substantial connection to Canada — specifically, at least 1,095 cumulative days of physical presence in Canada at any point before the child’s birth. Those days do not need to be consecutive. |
| What documentation is needed to apply for a Canadian citizenship certificate under Bill C-3?
Applicants typically need to document the chain of Canadian citizenship through their family line — including birth certificates, marriage certificates, and any records confirming the Canadian citizenship status of the ancestor through whom the claim flows. Canadian provincial archives hold historical vital records. Many archives are currently experiencing significant delays due to the surge in requests. |
| Does a Canadian citizenship certificate allow an American to work in Canada?
Yes. Canadian citizens have the right to live and work in Canada without a work permit. However, if you are still in the application process awaiting your certificate, you do not yet have confirmed Canadian citizenship status and your right to stay and work in Canada remains governed by your current immigration status. |
| Where do I start if I think I may be eligible for Canadian citizenship under Bill C-3?
Start with a consultation with an immigration lawyer or regulated Canadian immigration consultant familiar with Bill C-3 descent rules. Before filing any application, also speak with a cross-border financial advisor to understand the FBAR, TFSA, and RRSP implications. Apply for the citizenship certificate through IRCC at canada.ca/en/immigration-refugees-citizenship. Current processing time is approximately 11 months. |
