Yes things are changing all the time.
Regarding the quarantine plan, a fully vaccinated Canadian returning to Canada does not have to quarantine. However, the App will ask you to fill in a quarantine plan in the event you have symptoms after arrival.

No hotels as of a couple months ago. Most people will enter their personal home address as a place the could isolate themselves only if necessary. However they will still ask you to fill this in. No more antigen test required to go to St Martin after November 1st as I mentioned already so that is one less step.

Hope that makes sense.
