Yes because a bunch of the Indycar crew guys who were unvaxxed couldn’t go to the race this past weekend in Toronto Canada. Lot of scrambling to put together alternate help.

For travel by air from Canada to the U.S., I believe the above is still the most current policy.... On June 12, 2022, they set aside the requirement for a negative WuFlu test before getting on a plane but said the ‘proof of vax status is still in effect’....
“The CDC order from December 2, 2021, requiring persons aged two and above to show a negative COVID-19 test result or documentation of recovery from COVID-19 before boarding a flight to the United States, is rescinded, effective June 12, 2022, at 12:01AM ET. This means that starting at 12:01AM ET on June 12, 2022, air passengers will not need to get tested and show a negative COVID-19 test result or show documentation of recovery from COVID-19 prior to boarding a flight to the United States regardless of vaccination status or citizenship. Of note, CDC’s Order requiring proof of vaccination for non-citizen nonimmigrants to travel to the United States is still in effect.”
And here is what it says on about point of entry crossings other than by air (June 13, 2022 was the latest update)... https://ca.usembassy.gov/covid-19-information-canada-3/
“All non-immigrant, non-U.S. citizen air travelers to the United States must be fully vaccinated and provide proof of vaccination status prior to boarding an airplane to the United States. In addition, fully vaccinated foreign nationals may also enter the United States at land ports of entry (POE) and ferry terminals.”
