I'm starting to think you don't know what you are talking about. "Monthly" booster shot??? Are you nuts? I'm not aware of booster shots being recommended by any country any more often than 6 to 8 months. This is another silly example of when more isn't better.

Most Canadians only received their second dose after March 2021. Canada has just started to roll out booster doses for the most vulnerable (the very elderly or immunocompromised). My wife and I are both seniors and received our second doses (Pfizer) in mid-June. So we will likely be eligible for a booster either just before or just after our trip to SXM. Either way, I'm not concerned.

You should also be aware if you are serious about coming to Canada, that the Canadian regulations currently don't care how many booster shots you may have had. They only want to know if you are fully-vaccinated. Also, an antigen test is not sufficient to enter Canada. Let's keep things accurate, please.
