What is the current deal with crossing a land border to Canada (Quebec) as a vaccinated adult, with unvaccinated children 12-17. I know that the rule is that they get arrival tests and need to quarantine. What is what really happens. Any issues getting across the border? Any issue with not doing tests if returning to the US the same day? I know that the border crossings in real life are indeed simpler than the website makes it seem.
Any current info would be appreciated.
