Sorry, I was thinking flying to US as you only need an Antigen test.   Coming home to to Canada you can also use the Rapid ID NOW NAAT tests which are FREE at all Walgreens. Media only tells you PCR tests. Always check the govt website list: https://travel.gc.ca/travel-covid/travel-restrictions/flying-canada-checklist/covid-19-testing-travellers-coming-into-canada#getting-tested
