This year marks the first since the start of the pandemic that Canada is fully open to tourists.

Canada imposed travel restrictions on tourists in March 2020 and lifted them for those fully vaccinated in late summer 2021. Effective April 1st, fully vaccinated tourists do not need to complete a COVID-19 test before entering Canada.
