Renouncing or Losing Canadian Citizenship: What You Need to Know

Most people work hard to obtain Canadian citizenship and never look back. But some Canadians reach a point where they need to seriously consider giving it up — and others worry about whether citizenship can be taken away from them without their consent.

These are two very different legal situations governed by the Citizenship Act. Renouncing Canadian citizenship is a voluntary, formal process you choose to start. Revocation is something the government can initiate, but only on very narrow grounds. Understanding the difference matters, because the consequences of each path are permanent and wide-ranging.

This article walks through both scenarios in plain language so you know what you are dealing with before making any decisions.

Part A — Voluntary Renunciation: Giving Up Your Citizenship by Choice

Why Do People Renounce Canadian Citizenship?

The most common reasons Ontarians consider renouncing Canadian citizenship include:

• Tax obligations. Some countries — most notably the United States — tax their citizens on worldwide income regardless of where they live. Holding dual citizenship can create complex, expensive filing obligations. Renouncing the second citizenship is sometimes part of a broader tax-planning strategy. (Tax implications are serious; always get advice from a tax professional before acting.)
• Foreign military service requirements. Some countries require their citizens to complete mandatory military service. Holding dual citizenship can create conflicting obligations, and renouncing one citizenship may resolve that conflict.
• Home country rules on dual citizenship. Not every country recognizes or permits dual citizenship. If your country of birth or another nationality you hold prohibits it, you may be required to renounce your Canadian citizenship to retain or obtain status elsewhere.
• Simplifying legal status. In some cases, people who have moved abroad permanently and no longer have practical ties to Canada decide to consolidate their legal identity in one country.

None of these reasons make renunciation an easy or casual decision. Once done, it is difficult to reverse.

Who Is Eligible to Renounce?

Under the Citizenship Act, you can apply to renounce Canadian citizenship if you meet these conditions (as of writing — confirm current requirements on Canada.ca):

• You are 18 years of age or older (minors generally cannot renounce on their own).
• You are already a citizen of another country, or you will become one as a result of renouncing. Canada will not accept a renunciation that would leave you stateless — you must have somewhere else to belong.
• You are not ordinarily resident in Canada — or, if you are, you meet specific circumstances set out under the Act. Residency requirements can be nuanced, so confirm the current rules with IRCC.

The Renunciation Process

The process runs through Immigration, Refugees and Citizenship Canada (IRCC). The general steps are:

1. Complete the application. You fill out the prescribed renunciation form and gather supporting documents, including proof of your other citizenship.
2. Pay the application fee. As of writing, IRCC charges a fee to process a renunciation application — confirm the current amount on Canada.ca before submitting, as fees change.
3. Attend an interview or appointment (if required). IRCC may require you to appear in person to confirm you understand what you are giving up and that your decision is voluntary.
4. Receive a Certificate of Renunciation. If approved, IRCC issues this document. Your Canadian citizenship ends on the date the certificate is issued. Surrender your Canadian passport — using it after renunciation is not permitted.

The timeline for processing varies. Do not make irrevocable arrangements (selling property, closing accounts, booking one-way flights) on the assumption that your application will be approved within a specific window.

What You Lose When You Renounce

Renunciation is permanent and the consequences are significant:

• You lose the right to live and work in Canada without a visa or permit. If you want to return to Canada to live, you would need to qualify under the immigration system like any other foreign national.
• Your Canadian passport becomes invalid and must be surrendered.
• You lose the right to vote in Canadian federal elections.
• You lose access to consular assistance from Canadian embassies abroad.

Can You Get Canadian Citizenship Back?

Yes — there is a legal route. The Citizenship Act provides for resumption of citizenship for former citizens who renounced. As of writing, former citizens may be eligible to apply to resume citizenship if they subsequently reside in Canada and meet the applicable requirements. The rules governing resumption are subject to change, and not everyone who renounced will automatically qualify. If you are thinking about renouncing and are uncertain about your long-term plans, speak with an immigration lawyer before you file anything.

Part B — Involuntary Loss and Revocation: Can the Government Take Your Citizenship?

A Brief Historical Note

For much of Canada's history, citizenship could be stripped for a wide range of reasons — marriage to a foreign national, long absence from Canada, service in a foreign military. Successive amendments to the Citizenship Act eliminated most of those grounds. Today, involuntary loss of citizenship in Canada is very narrow.

Current Grounds for Revocation

Under the Citizenship Act as it currently stands, the federal government can seek to revoke citizenship where it was obtained through fraud or misrepresentation in the application process. This typically means situations where someone provided false documents, concealed criminal history, or made material misrepresentations to obtain citizenship they would not otherwise have received.

The law does not permit revocation simply because someone lives abroad, holds another citizenship, or falls out of favour politically. Citizenship is not conditional on ongoing ties to Canada once it is granted.

The Revocation Process and Your Rights

Revocation is not automatic. The process involves formal notice to the person affected, an opportunity to respond, and — importantly — access to the courts. As of writing, someone facing revocation proceedings has the right to seek judicial review. If the matter proceeds and citizenship is revoked, the person ordinarily becomes subject to removal from Canada.

Given the serious consequences, anyone who receives notice of potential revocation proceedings should consult an immigration lawyer immediately.

The Bottom Line on Involuntary Loss

For the overwhelming majority of Canadian citizens, citizenship is stable. You will not lose it by living abroad, taking out citizenship elsewhere, or failing to use your Canadian passport. The practical risk of involuntary revocation applies to a very small group of people who obtained citizenship through fraud — not to ordinary Canadians going about their lives.
