Avoid These 5 eTA Application Errors Before They Cost You Your Trip to Canada

Applying for a Canadian Electronic Travel Authorization is designed to be quick and straightforward. In most cases, approval arrives within minutes. However, a surprisingly large number of applicants encounter problems—not because the system is flawed, but because avoidable errors creep into the application at critical moments.

A rejected eTA does not simply mean a delay. It can result in being denied boarding at your departure airport, missing non-refundable flights, and facing additional scrutiny on future applications. Understanding the most common mistakes—and how to sidestep them—is essential for any traveller planning to visit Canada.

Mistake 1: Entering Passport Information Incorrectly

The single most frequent cause of eTA complications is inaccurate passport data. The eTA is electronically linked to the specific passport number you provide during the application. Even a single transposed digit or misplaced letter can cause a mismatch that prevents you from boarding your flight.

What goes wrong: Travellers often enter their passport number from memory or misread digits under poor lighting. Common errors include confusing the letter "O" with the number "0," or "I" with "1." Others enter an expired passport number out of habit.

How to prevent it: Always have your physical passport open in front of you when completing the application. Double-check the passport number, expiry date, and date of issue character by character before proceeding. Ensure you are using the passport you intend to travel with—not one that has since been renewed or reported lost.

If it happens: An eTA issued with incorrect passport details is effectively invalid. You will need to submit a new application with the correct information and pay the CAD $7 fee again. There is no amendment process for an existing eTA.

Mistake 2: Providing a Name That Does Not Match Your Passport

Your name on the eTA application must correspond precisely to the name as it appears in your passport's machine-readable zone—not how it appears in everyday usage, not a shortened version, and not a married name if your passport still reflects your previous surname.

What goes wrong: A traveller named "María José García López" might habitually write "Maria Garcia" in online forms. A South Korean applicant might reverse the order of their given name and family name. A recently married traveller might enter their new surname without updating their passport first.

How to prevent it: Copy your name exactly as it appears on the biographical data page of your passport. If your passport uses all capital letters, do not assume this matters for the application—enter the name as shown. Pay particular attention to hyphens, accents, and compound names.

Real-world consequence: Airline check-in staff are required to verify that your boarding pass, eTA, and passport all reflect the same name. A discrepancy can result in denied boarding even if your eTA was technically approved.

Mistake 3: Misunderstanding eTA Eligibility Based on Nationality

Many travellers assume that because they live in or hold residency in a visa-exempt country, they are automatically eligible for an eTA. Eligibility, however, is based on citizenship—not residency.

What goes wrong: A citizen of India who has lived in the United Kingdom for fifteen years and holds a British residence permit may assume they qualify for the eTA pathway. In most cases, they do not. eTA eligibility is determined by the passport you hold, not where you reside. Similarly, dual nationals sometimes apply using the wrong passport.

How to prevent it: Before beginning your application, verify your country of citizenship against the official IRCC list of eTA-eligible nations. If you hold dual citizenship and one of your nationalities is Canadian, you must travel using your Canadian passport and do not require an eTA at all. If one of your nationalities is from a visa-exempt country, use that passport for your eTA application.

An important exception: Some citizens of non-visa-exempt countries may still qualify for an eTA if they hold a valid U.S. non-immigrant visa or a valid Canadian visa. Check the specific eligibility rules carefully before assuming you must apply for a full Temporary Resident Visa.

Mistake 4: Failing to Disclose Previous Refusals or Criminal History

The eTA application asks several background questions, including whether you have ever been refused a visa or entry to any country, and whether you have a criminal record. Many applicants either misunderstand these questions or deliberately omit relevant information, believing it will not be discovered.

What goes wrong: A traveller who was refused a U.S. visa ten years ago may not consider it relevant to a Canadian application. Someone with a minor criminal conviction from their youth may assume it is too old to matter. Both of these assumptions can lead to serious problems.

How to prevent it: Answer all background questions honestly and thoroughly. Canada's border services have access to shared intelligence databases, including information exchanged with Five Eyes partner nations such as the United States, the United Kingdom, Australia, and New Zealand. Providing false information on an eTA application is considered misrepresentation and can result in a ban from entering Canada for up to five years.

If you have a criminal record: Depending on the nature and age of the offence, you may still be admissible to Canada. However, you may need to apply for Criminal Rehabilitation or a Temporary Resident Permit rather than relying solely on an eTA. Consulting an immigration professional is advisable in these circumstances.

Mistake 5: Applying Too Late Before Your Flight

While the vast majority of eTA applications are approved within minutes, a significant number are flagged for additional review, which can extend processing to 72 hours or more. Some applicants—particularly those with complex backgrounds—may wait several days before receiving a decision.

What goes wrong: Travellers frequently apply for their eTA on the day of departure, assuming instant approval. When their application is held for further review, they face an impossible situation: their flight departs before their eTA is processed.

How to prevent it: Apply for your eTA as soon as your travel plans are confirmed—ideally at least two to four weeks before your departure date. There is no advantage to waiting, and there is considerable risk in leaving it until the last moment. The eTA does not have a fixed start date, so early approval does not affect its validity.

What to do if processing is delayed: Contact IRCC directly for a status update. Do not book non-refundable flights until you have received confirmation of your eTA approval, particularly if your application involves any of the background factors mentioned above.

A Final Word on Getting It Right

The Canadian eTA process is genuinely one of the simpler entry requirement systems in the world. The fee is minimal, the form is brief, and approval is typically swift. The errors outlined above are not the result of a complicated system—they stem from rushing, inattention, or incomplete research.

Taking an extra fifteen minutes to review your application carefully, cross-reference your passport details, and confirm your eligibility can mean the difference between a seamless journey to Canada and a stressful, costly setback. Treat the eTA application with the same care you would give to any important travel document, and your trip is far more likely to proceed without incident.
