What is the definition of a fully vaccinated passenger?

A fully vaccinated traveller arriving in Canada must have received the full series of a COVID-19 vaccine — or combination of vaccines — accepted by the Government of Canada, with the last dose administered at least 14 days prior to arrival in Canada. These vaccines do not need to be administered in Canada to qualify. Currently, those vaccines that are accepted are manufactured by Pfizer-BioNTech, Moderna, AstraZeneca/COVISHIELD, and Janssen (Johnson & Johnson). Travellers must provide proof of vaccination in English or French (or a certified translation, along with the original).
