You will not lose your US passport by claiming Canadian citizenship. Both the United States and Canada allow dual citizenship for most people, and millions of citizens of both countries legally hold more than one passport. Canada also does not tax you based on citizenship. It taxes based on residency. If you live in the United States and claim your Canadian citizenship by descent, your US tax situation stays exactly the same.

Thousands of Americans are digging through family records right now. Recent legal and legislative changes have significantly expanded eligibility for Canadian citizenship by descent, and millions of people with Canadian ancestry may now be newly recognized or newly eligible. Many do not know it yet.

But fear is stopping a lot of them. They are hearing things from friends, reading half-finished articles online, and walking away convinced that claiming Canadian citizenship will cost them their American passport or trigger a nightmare tax situation.

Most of what they are hearing is wrong. Let me walk you through the most common myths, one by one, with the actual facts.

Key Takeaways: What You Need to Know Right Now about Claiming Claiming Canadian Citizenship as American

Claiming Canadian citizenship by descent does NOT affect your US passport or US citizenship in any way.
Canada taxes based on where you live (residency), not what passport you hold. No new Canadian tax obligations arise just from holding a certificate.
The US still taxes you on worldwide income because that is how the US tax system works. That obligation existed before. It does not change.
Proposals to restrict dual citizenship surface occasionally in US politics. None are currently law, and none are close to passing.
If you eventually move to Canada, cross-border tax planning becomes important. But for most people who stay in the US and do not establish financial ties to Canada, nothing changes.
Processing times for a Canadian citizenship certificate are currently around 10 to 12 months, subject to change based on application volume. The sooner you apply, the sooner your clock starts.

Will Claiming Canadian Citizenship Cancel My US Passport?

No. Claiming Canadian citizenship by descent does not cancel, suspend, or affect your US passport in any way. Both the United States and Canada officially permit dual citizenship. The modern legal framework protecting dual citizenship in the United States comes largely from the Supreme Court’s 1967 decision in Afroyim v. Rusk, which held that US citizens cannot be stripped of their citizenship without a voluntary, intentional renunciation. Canada has allowed it since 1977. You do not need to notify the US government. No paperwork, no reporting requirement, no registration.

This is the biggest fear I hear. And it is understandable. The internet is full of outdated information and half-truths about citizenship rules from other countries where dual citizenship is restricted.

Canada and the United States are not those countries.

The US State Department openly acknowledges that many American citizens hold citizenship in other countries. There is no general US law, regulation, or executive order that forces you to choose between your US and Canadian citizenships, though certain sensitive government roles can have their own restrictions. When you become a Canadian citizen, the US government does not receive notification. No alarm goes off. Nothing changes on your end.

You will continue to enter and leave the United States on your US passport. You will enter Canada on your Canadian passport. That is standard practice for dual citizens. Border agents in both countries know how this works.

What actually causes someone to lose US citizenship?

You only lose US citizenship through a voluntary, formal act of renunciation at a US consulate or embassy abroad, combined with a clear intent to give up your status. Simply holding a foreign passport does not trigger loss. Neither does living in another country. Neither does claiming an ancestral citizenship. (US State Department, 8 U.S.C. Section 1481)

This is worth understanding clearly. The law requires both the act AND the intent. US courts and the State Department treat naturalization in another country as not causing loss of US citizenship by itself, unless you clearly intended that act to give up your US status.

Claiming your Canadian citizenship by descent is about formalizing a status you may already have under Canadian law. You are not acquiring something new so much as confirming what already exists. That is even further from any scenario that could affect your US status.

What About Proposals to Ban Dual Citizenship in the US?

Proposals to restrict dual citizenship surface occasionally in US politics, but as of May 2026 none have become law. Dual citizenship remains legal for American citizens under current US law and Supreme Court precedent. If you hold or acquire Canadian citizenship, your US status is not affected by any current legislation or regulation.

This question comes up a lot, and it is worth addressing directly. From time to time, US legislators propose bills that would restrict Americans from holding foreign citizenship. These proposals tend to generate significant media coverage and concern among people who are considering claiming a second citizenship.

The reality is that such proposals face significant legal, constitutional, and logistical barriers. No proposal of this nature is currently law. No proposal is currently close to passing.

Dual citizenship between the US and Canada is firmly established. The US has permitted it since the Supreme Court ruling in Afroyim v. Rusk (1967). Canada has permitted it since 1977. Both countries have built their immigration and citizenship systems around the reality that many of their citizens hold dual status.

Myth

“The US is about to ban dual citizenship so I should wait before applying.”

Fact

Dual citizenship is a fully legal right now. Waiting only pushes you further back in a queue that is already 10 to 12 months long. Apply now and secure your status while the law is clear.

Will Claiming Canadian Citizenship Mean I Pay Canadian Taxes?

Canada uses residency‑based taxation, not citizenship‑based taxation, as explained in Canada Revenue Agency guidance on tax residency. Simply holding a Canadian citizenship certificate while living in the United States creates zero Canadian income tax obligations. You would only become subject to Canadian taxes if you move to Canada and establish tax residency there. (Canada Revenue Agency, 2026)

This is the second biggest fear I hear. And it makes sense that people worry about it, because the US tax system works so differently.

The United States is one of only two countries in the world that taxes its citizens on worldwide income, regardless of where they live. That is citizenship-based taxation. If you are American, you file with the IRS every year. Full stop.

Canada does not work that way. Canada taxes you based on whether you live there. The moment you hold a Canadian citizenship certificate, your tax situation does not change at all unless you actually pack up and move.

Think of it this way: Canadians who move to the US stop paying Canadian income taxes. They pay US taxes instead, because they now live in the US. The same logic applies in reverse. If you are an American with Canadian citizenship living in Ohio, Canada has no claim on your income.

What if I already pay US taxes? Does that change?

For most people who remain in the US and do not establish financial ties to Canada, nothing changes. The US tax obligation existed before you claimed Canadian citizenship. It exists because you are American, not because of anything Canada does. You continue filing Form 1040 with the IRS annually, reporting worldwide income, exactly as you did before. (IRS, 2026)

A lot of people think claiming Canadian citizenship adds a new obligation on top of what they already have. It does not add Canadian tax obligations. Your existing US filing requirements stay the same.

The only scenario where Canadian taxes enter the picture is if you decide to move to Canada and become a Canadian tax resident. That is a separate decision you make later. And if you do make that move, the US-Canada Tax Treaty provides tools specifically designed to prevent you from being taxed twice on the same income.

What Are the Real Tax Considerations for US-Canada Dual Citizens?

If you live in the US and hold Canadian citizenship, your only tax filing obligation is your regular US return. If you move to Canada, you must file both a US Form 1040 (because the US taxes by citizenship) and a Canadian T1 return (because Canada taxes by residency). The US-Canada Tax Treaty prevents double taxation in most cases. (IRS and CRA, 2026)

Let me separate the two situations clearly.

Situation 1: You claim Canadian citizenship and stay in the United States. For most people, nothing changes. File your US taxes as usual. No Canadian tax return required. That said, if you open Canadian financial accounts, US reporting rules like FBAR and FATCA may come into play. Those rules apply to any US person with foreign accounts. They are not triggered by citizenship. They are triggered by the accounts themselves.

Situation 2: You claim Canadian citizenship and eventually move to Canada. Now both tax systems come into play. You still file a US return because you are American. You also file a Canadian return because you now live in Canada. Here is where cross-border tax planning matters a great deal.

There are some genuine complexities if you move to Canada and start investing there:

TFSA accounts: Tax-free in Canada, but the IRS may treat them as taxable foreign trusts. This is a real issue that requires professional attention.
FBAR reporting: If your Canadian financial accounts total more than $10,000 USD at any point in the year, you must file FinCEN Form 114 with the US Treasury. The threshold is aggregate, not per account.
FATCA Form 8938: Required if foreign financial assets exceed certain thresholds (generally $50,000 for US residents, $200,000 for those living abroad).
RRSP accounts: Generally treated more favorably under the US-Canada Tax Treaty, but require a specific IRS election to defer US tax on investment growth inside the account.
Foreign Earned Income Exclusion: If you live and work in Canada, you may be able to exclude a substantial amount of earned income (over USD 130,000 for 2026) from US taxable income under the Foreign Earned Income Exclusion, subject to IRS limits for that year..

Important: The information above is general in nature. Cross-border tax situations vary significantly based on individual circumstances. Work with a cross-border tax professional, not a general accountant, if you move to Canada.

Situation	US Tax Obligation	Canadian Tax Obligation	New After Claiming Citizenship?
You live in the US and claim Canadian citizenship	File Form 1040 annually. Report worldwide income.	None. You are not a Canadian tax resident.	No change whatsoever.
You move to Canada after claiming citizenship	Still file Form 1040. US taxes by citizenship.	File T1 return. Canada taxes by residency.	Canadian obligations arise from the move, not the citizenship.
You have Canadian bank accounts exceeding $10,000 USD	Must file FBAR (FinCEN 114) annually.	Normal Canadian tax treatment.	FBAR applies to any US person with foreign accounts. Always did.

What Does the Dual Citizenship Application Process Actually Look Like?

Americans claiming Canadian citizenship by descent apply to IRCC for a Citizenship Certificate (Form CIT 0001). As of May 2026, Processing times for a Canadian citizenship certificate are currently around 12 months, and can change based on application volume. You will need to document your chain of descent from a Canadian ancestor. The certificate fee is $75 CAD. After receiving the certificate, you can apply for a Canadian passport separately.

The process is straightforward, though document gathering can take time. Here is how it works step by step.

Confirm your eligibility. Recent legal and legislative changes have significantly expanded eligibility for citizenship by descent. If you were born before December 15, 2025, and can trace your lineage to a Canadian ancestor, you may already qualify under the expanded citizenship‑by‑descent rules, depending on how the new law applies to your family history..
Gather your document chain. You need birth certificates connecting each generation from you back to your Canadian ancestor. Marriage certificates where names changed. Any existing Canadian citizenship documents in the family.
Complete Form CIT 0001. This is the Application for a Citizenship Certificate.
If using a representative, complete Form IMM 5476. This is required for any professional to act on your behalf.
Submit and wait. Current processing is around 12 months (often in the 10–12 month range), subject to change based on application volume. Tens of thousands of applications were in the queue as of early 2026, driven by a surge in American applicants.
Receive your Citizenship Certificate. This is your proof of citizenship. You can then apply for a Canadian passport separately.

One important note: applications are date-stamped. If your application packet is dated more than 90 days before IRCC receives it, it is returned as incomplete. Do not prepare everything and then let it sit.

Document gathering is also where most Americans hit delays. In some cases, older Quebec birth certificates may need to be replaced with updated versions from the Directeur de l’etat civil, depending on format and completeness. Translations of any non-English, non-French documents must be done by a certified translator, not a family member.

Why Are So Many Americans Applying Right Now?

Recent legal and legislative changes have significantly expanded eligibility for Canadian citizenship by descent, with further reforms still in progress. This has opened the door for potentially millions of Americans with Canadian ancestry who may not have qualified under older rules. IRCC reported that in early 2026, US applicants exceeded the combined volume from the next nine source countries.

The timing is not an accident. The changes are genuinely significant. For years, restrictive rules cut off citizenship eligibility at one generation born abroad. Recent court rulings and legislative action have challenged and expanded those limits, and many more people now qualify than did just a few years ago.

The response has been enormous. Archives in Quebec reported a 3,000% increase in requests for vital records. IRCC saw application volumes surge to historic levels. Processing times that were 5 months in 2025 stretched to 10 to 12 months by early 2026.

People are applying for all kinds of reasons. A second passport that currently provides visa-free access to over 185 countries. The right to live and work in Canada without any additional visa. Access to Canadian healthcare when they move there. The ability to sponsor family members. And yes, for some, a geographic backup plan given the current political climate.

The reasons are personal. The eligibility question is real. And the process, while slow right now, is worth starting sooner rather than later for anyone who believes they may qualify.

Frequently Asked Questions

Does claiming Canadian citizenship affect my US Social Security?

No. Holding Canadian citizenship does not affect your US Social Security benefits or eligibility. The US‑Canada Tax Treaty contains specific provisions covering Social Security benefits to help reduce withholding. Social Security is tied to your US work history and age, not to what other passports you hold. If you move to Canada and begin receiving US Social Security there, the US‑Canada tax treaty includes specific rules on how those benefits are taxed, which can help reduce or avoid double taxation.

Do I need to tell the US government I became a Canadian citizen?

There is no requirement to report acquiring Canadian citizenship itself to the US government. The US State Department acknowledges that many Americans hold citizenship in other countries and does not require notification. Your regular US tax reporting rules still apply. If you later hold Canadian financial accounts or assets, standard US reporting obligations like FBAR and FATCA may apply, as they do for any US person with foreign accounts.

Can I pass Canadian citizenship to my children?

It depends on when your children were born and on the specific rules that apply to your family situation. For children born before December 15, 2025, expanded eligibility rules under recent legislative changes may apply. For children born on or after December 15, 2025, a “substantial connection” requirement applies, meaning the Canadian parent generally needs to have been physically present in Canada for at least 1,095 days before the child’s birth. Individual cases vary, and this is an area where professional advice matters.

What is the $75 CAD citizenship certificate fee and what does it cover?

The $75 CAD fee is the IRCC government processing fee for your Citizenship Certificate (Form CIT 0001), which is your official proof of Canadian citizenship. It does not cover document retrieval, certified translations, courier costs, or the separate cost of applying for a Canadian passport afterward. Budget for these additional expenses, especially if your documents require translation or certified copies from provincial archives.

How long does it take to get a Canadian citizenship certificate in 2026?

As of May 2026, IRCC processing times for citizenship certificates are approximately 10 to 12 months, subject to change based on application volume. Applications from outside Canada and the United States may take an additional 3 to 4 months for mailing. Document gathering can add 1 to 3 months before you even submit. Starting the process now rather than later is strongly advisable given the volume of current applications.

Will I face double taxation if I hold both US and Canadian citizenship?

As long as you live in the United States, no. You pay US taxes as always. If you move to Canada, you will need to file both a US tax return and a Canadian tax return, but the US-Canada Tax Treaty has specific provisions designed to prevent the same income from being taxed twice by both countries. The Foreign Tax Credit and the Foreign Earned Income Exclusion (up to $132,900 in 2026) are the primary tools most dual citizens use to manage their US tax obligations when living in Canada.
