Many people reapply to the eTA immediately after a refusal. Most should not.
The refusal letter you received is not a formality. It is a diagnosis. Read it carefully before you do anything else, because it tells you which of two very different paths is open to you: fix the problem and reapply, or seek legal review. Submitting a new application when the underlying issue is inadmissibility or misrepresentation won’t just fail again — it can make your situation harder to resolve. The first thing to do after a refusal is read the letter, not open a new application tab.
What a refusal means right now
An eTA refusal does not bar you from Canada permanently, but it does mean you cannot board a flight to Canada without resolving whatever triggered the decision. The eTA is electronically linked to your passport, so a refused application is tied to that document. A new passport won’t clear the record if the underlying reason for refusal travels with you.
It also means your travel plans are genuinely at risk. If you have booked flights, contact your airline and accommodation now, before you know the outcome of any next step. Most refusals are not resolved in days, and obtaining an eTA at the last minute may not be possible depending on your situation. Buying time by notifying your carriers is practical, not pessimistic.
One more thing the letter signals: a refused eTA does not mean Canada is entirely closed to you. Depending on why you were refused, a visitor visa rather than an eTA may be the correct document for your situation. That route involves more paperwork and a longer timeline, but it exists precisely for cases where the eTA stream isn’t the right fit.
How to read your refusal letter and diagnose your situation
Your refusal letter will not always spell out the reason in plain language, but it will contain enough to place you in one of two categories.
The first category is administrative or factual error. This covers situations where something went wrong with the application itself: a passport number entered incorrectly, a question answered inaccurately due to misunderstanding, or information that was incomplete rather than deliberately withheld. If your letter points to a discrepancy in your application details, or if you can identify a clear mistake you made, you are likely in this category.
The second category is inadmissibility. This is where the refusal is based on something about you rather than something about the form. Inadmissibility grounds include criminal history (including a DUI), involvement in organised crime or people smuggling, security concerns, health grounds, financial reasons (specifically, inability or unwillingness to support yourself in Canada), misrepresentation under the Immigration and Refugee Protection Act, or having a family member who is themselves inadmissible. If your letter references any of these, or uses language about your personal history, background, or prior immigration record, you are in the second category.
The distinction matters enormously. Category one is often fixable by reapplication. Category two is not, and attempting to reapply without addressing an inadmissibility finding is not just futile: providing false or incomplete information in a subsequent application constitutes misrepresentation, which is itself a ground for inadmissibility…
If your letter is ambiguous, a Canadian immigration lawyer can read it and tell you which category applies. That consultation, even a brief one, is worth more than a second application submitted in hope.
The reapplication path: when it makes sense and what must change
If your refusal stems from a factual error in your original application, reapplying is the right move. The important constraint is that something must genuinely be different in the new application. Submitting the same information a second time will produce the same result.
What counts as a genuine change depends on what went wrong. A wrong passport number, a misread question, a nationality field filled in incorrectly — these are correctable. If you entered your passport details incorrectly, that alone may have been enough to prevent travel, and a fresh application with accurate information resolves it. There is a useful guide on correcting mistakes on a Canada eTA application that covers this in more detail.
Changed circumstances can also support reapplication. If you were refused partly because of a prior overstay or an unresolved immigration matter that has since been formally closed, a new application accompanied by documentation of that resolution has a different evidentiary basis than the original.
What does not support reapplication: submitting the same application with no changes and hoping for a different officer, or omitting information from your history because you think it won’t be found. The system retains your prior application history. Omitting information that is directly relevant to a decision under IRPA is the definition of misrepresentation, and a finding of misrepresentation creates an inadmissibility of its own.
When you do reapply, answer every question accurately and completely. If a question asks about criminal charges and you have a charge that was withdrawn or stayed, answer honestly and include documentation. The application requires a valid passport, a credit or debit card, and an email address. Some decisions may take up to a few days, with an email expected within 72 hours of applying, worth knowing if you are working against a travel deadline.
When judicial review is the right move
Inadmissibility findings call for a different mechanism: judicial review by the Federal Court of Canada. This is not an appeal in the ordinary sense. The Federal Court does not reassess whether you should have been granted an eTA on the merits; it reviews whether the officer’s decision was made correctly, following proper procedure and applying the law as written.
You can ask the Federal Court to review an immigration decision, but there are strict timelines for doing so, and the process requires legal representation in practice. This is not a path to pursue without a lawyer who practises Canadian immigration law.
Judicial review is appropriate when you believe the officer made a legal error — applied the wrong standard, ignored relevant evidence, or reached a conclusion that no reasonable decision-maker could reach on the facts. It is not appropriate simply because you disagree with the outcome or believe the officer was too strict.
If inadmissibility is the issue, there may also be other routes depending on your specific ground. Criminal inadmissibility, for example, can sometimes be addressed through a Temporary Resident Permit or a finding of Criminal Rehabilitation — these are separate processes, handled through IRCC, and they address the underlying inadmissibility rather than challenging the eTA refusal directly. A lawyer can tell you which route fits your circumstances.
One scenario worth naming separately: if your refusal references misrepresentation, that finding carries its own consequences under IRPA and affects future applications beyond just the eTA. Treat a misrepresentation finding as a legal matter from the outset.
Mistakes that make a refusal harder to reverse
The most common mistake is reapplying immediately without reading the letter. The second most common is reapplying with corrected details when the problem was never the details — when the real issue is inadmissibility and no amount of accurate form-filling will change the outcome.
A third mistake is omitting information in a reapplication because it feels risky to disclose. This is the logic that turns a fixable refusal into a misrepresentation finding. If something in your history is relevant to the questions on the form, disclose it. An officer who sees a disclosed prior charge and a resolved outcome is in a different position than one who finds an undisclosed charge through background checks.
Leaving travel arrangements in place while you sort this out is also a mistake with real financial consequences. Refusals are not resolved on airline timelines. If your departure is within days and your refusal is based on anything more than a simple data error, the realistic outcome is that you will not travel on those dates. Acting on that early — contacting your airline, checking your travel insurance terms — limits the financial damage.
Finally, do not assume that because you hold a passport from a country that normally qualifies for the eTA, the refusal must be an error. Possessing a qualifying passport and having a valid eTA are two different things, and even a valid eTA does not guarantee entry into Canada. The eTA is a pre-screening tool, not a guarantee, and a refusal means the pre-screening found something that needs to be addressed before you travel.
