How is this different from having to provide proof of yellow fever vaccination?

Because the VAXPORTS will be used here not to enter the country
(which would not stop entry of the virus anyway)
but to travel inter-provincially, within your own municipality, even ENTER STORES and YOUR OWN APARTMENT BUILDING and conceivably even
to enter your own house if your family lives there.

Oh, and who is to say that if we want our passport to continue to be valid
that they don't give us "vaccine" intended to sterilize us, or that they will force us to surrender all property to the government?

That's how it's different. Your idea of a passport is for entry into your county.
THEIR idea of a passport is to (first) monitor (and then control) your every movement within your country, then province, then city, then .. what?

You have too much trust of government. They have an agenda.
The first thing Hitler did when he came to power is confiscate all the guns
just like Liberals are doing now. You probably didn't know that
but I hope you know what Hitler did "next" and what Canada, UK and USA
did to stop it. But there is nobody in the world who can help "us".
