Sucks that the first search result is useless. NONE of that was needed when I went in December except my covid test result

Looks like you just need to use the ArriveCAN app and proof of vaccination.
Though, when I want in December they only wanted my passport and test results. Didn't look at my vaccination card when I arrived. Because it was my first time they asked me questions and wanted my hotel info. Looks like things are easing up now
