I see there’s still a lot of confusion about testing requirements. For example, at no time are you ever required to get the “$200” PCR test to board a plane, or cross the border.
To board a plane to the US a Rapid Antigen ($40 at Shoppers in some places) is fine. To come back an NAAT (free at Walgreens) is fine.
And no test of any kind is needed to enter the US by land - that is, if you are allowed to do so (ie Dual Citizen, essential worker). And, technically, if you are a legal resident of Canada somehow driving back, although you are indeed still “required” to provide a negative test, they can’t actually deny you entry no matter what (although you may be told to quarantine).
