21. If an individual received a work permit or study permit at a Canadian Port of Entry but did not received a confirmation letter afterwards, how would he or she check whether he or she has been issued an eTA and what the eTA number is?
In this instance, in order to obtain the eTA number, the individuals should submit a case-specific enquiry form to Immigration, Refugees and Citizenship Canada (IRCC) explaining the situation. An email response from IRCC will contain the eTA number.
