Preparing an electronic travel authorization (eTA) application is easier when the required details are gathered before the form is opened. This checklist keeps the preparation sequence focused on facts mapped to current Government of Canada sources.
If you are ready to organise the required information, you can prepare your eTA application alongside the official instructions. Keep the passport you intend to use for travel in front of you throughout the process.
Start With the Official Requirements
The Government of Canada provides an online eTA process and instructs applicants to use a valid passport. The official Canada.ca eTA overview is the primary reference for this requirement.
The official application guidance lists a valid passport, a valid email address, and an accepted payment method among the required application inputs. Place those three items within reach before opening the form so the information can be copied directly from the documents and accounts you control.
Prepare for One Uninterrupted Form Session
The official online application form cannot be saved, so applicants should have their information ready before starting. A simple preparation pass reduces the need to pause while searching for an input.
Use this order before starting:
- Open the passport you will use for travel.
- Confirm the email address you intend to enter.
- Put the accepted payment method nearby.
- Open the official application page only after all inputs are ready.
Copy the Passport Number Carefully
An eTA is electronically linked to the traveller’s passport, and an incorrect passport number can cause problems when flying to Canada. Read the number from the passport itself and compare it with the form before submission.
Do not rely on memory or on details saved from another document. The passport used in the application is the document referenced by the eTA.
Use the Government Website
The Government of Canada instructs travellers to apply for an eTA only on its official website. Use the official eTA application guidance on Canada.ca as the application reference.
Keeping the official page open also makes it easier to check the current instructions without relying on an unsourced summary.
Check Whether the Passport Has Changed
If a traveller gets a new passport, the Government of Canada says they need to get a new eTA. Compare the passport in your hand with the document used for any earlier eTA before planning to travel.
The Government of Canada eTA facts page is the mapped source for the passport-link rule.
Pre-Application Decision Box
| Check | Ready to proceed? |
|---|---|
| Valid passport is in front of you | Yes / No |
| Valid email address is available | Yes / No |
| Accepted payment method is available | Yes / No |
| Information is ready before the non-saveable form is opened | Yes / No |
| Passport number has been compared with the form | Yes / No |
| Application page is the official Government of Canada website | Yes / No |
| New passport, if applicable, has a new eTA | Yes / No |
If any answer is “No,” pause before opening or submitting the form. Complete the missing preparation step, then return to the checklist.
What Happens After You Submit
Once the form is submitted, the preparation checklist above is behind you, but a short follow-up sequence still matters. Understand what the approval notification looks like before it arrives, so you recognise it immediately rather than second-guessing whether an email is genuine. If more than the typical processing window passes without a decision, check your eTA status rather than resubmitting a second application against the same passport.
If You Notice an Error After Submitting
The checklist above is built to prevent errors before they happen, but if one slips through anyway — a mistyped passport number, a name that doesn’t match the passport exactly — don’t assume the application is unrecoverable. Review the guidance on correcting a submitted eTA application for the specific next step, since the right fix depends on which detail was entered incorrectly.
Why Preparation Matters More Than It Seems
The official form’s inability to save partial progress is the main reason this checklist front-loads everything. An applicant who starts without their payment method nearby, or without having confirmed their exact passport number, often ends up re-entering information from memory under time pressure — which is exactly the condition that produces the passport-number errors covered above. Working through every item in the Pre-Application Decision Box before opening the form removes that pressure entirely.
Final Verification
Keep the final check short: valid passport, valid email address, accepted payment method, correct passport number, and the official website. If the passport is new, apply the verified new-passport rule before travelling.
For a final orientation before you begin, review common eTA questions, then use the mapped Canada.ca sources for factual confirmation.
