PCR test requirement is done by the Feds to try and prevent people from travelling or make cumbersome rules that are somewhat confusing to navigate.
It appears land travel to U.S. requires no test at all. Air travel to U.S. requires an antigen test. Both methods will require non-essential travelers to be fully vaccinated.
But the return requirements to Canada are stupid.
And then there is the travel advisory issue. Currently the Feds say 'Avoid non-essential travel outside Canada until further notice'. (Link at bottom) I know some companies are following this as gospel. Because of this, there may be some rules from the employer on employee international travel as well.
