From today Canada is open to vaccinated Americans. [USA Today] Frustratingly and embarrassingly Canadians are not allowed into the USA.

The process is not as simple as before the pandemic but at least the border is open, one way. " The country has implemented new health measures to keep the coronavirus at bay, such as asking visitors to provide additional documentation – including proof of vaccination and a coronavirus test – before crossing the land border. Air travelers also need to submit information, including coronavirus test results, before boarding a plane to Canada. Falsifying information could result in hefty fines. " https://eu.usatoday.com/story/travel/news/2021/08/08/canada-border-reopen-what-to-know-before-travel-canada-covid/5505783001/
