18. I leave for Canada in a few days but I cannot submit the additional documents required for my eTA application by the requested deadline. Can I still travel to Canada?

If you are waiting for someone (e.g. police department, doctor) or another third party to send you documents, or have problems uploading the documents and cannot submit them by the deadline, you may submit a case specific enquiry to request an extension to the deadline.
As of August 1, 2015, individuals who are issued an initial study or work permit will automatically be issued an eTA along with their permit. For work permit or study permit renewal applications, the eTA will not be automatically renewed. If you wish to exit and re-enter Canada by air, you will need to ensure that your eTA is still valid. If your eTA has expired, you will need to apply for a new one as soon as you can and before the eTA leniency period ends on September 29, 2016.
