We are currently in the Turks and Caicos. This certainly messed up our mood yesterday.
I called the CBSA to confirm our ability to drive from the US into Canada (one of my plan Bs - strange, alamo for example seems to offer one way rentals into Canada). The agent says, oh these new policies are effective January 6. I asked her are you referring to the pre-boarding covid test requirement announced at the press conference a couple of hours ago. She said yes, we don't have any of the details yet, but the date is January 6.
I calles again to speak to a different agent and sure enough he said the same thing, no idea what the details will be but goes live January 6.
To my knowledge no one in the press has reported this yet...
