Applying for an eTA online is pretty straight forward. If you have all the necessary information and documentation, the process of completing your application will only take you 10 minutes. Once you have filled out the application form, submitted the payment and received the approved eTA in your inbox you will be able to travel to Canada for up to 6-months travels per entry and the eTA will be valid for a total of 5 years starting with the date of issue or until the passport expiration date. If your passport has expired you will need to apply for a new eTA, the same applies for the eTA itself, if your travel authorization has expired you may apply for a new one. Once you have the necessary information as well as the documents to apply for an eTA, you will need to fill out an online eTA application which must be done at least 72 hours before departing. Once the application has been completed and the payment has been confirmed you will be notified via email. Normally your eTA will be issued within the first 24-48 hours if no further information is required. In some cases, the process might take up to a few weeks, and you might be required to present additional documents.
