If the border was about to reopen, would the U.S. be telling its citizens not to visit Canada?

WASHINGTON-During the two weeks I recently travelled back to Canada to visit family for the first time in way-too-long, I got a lot of questions from Canadians wondering when they might be able to drive to the U.S. for a similar trip. That information, as I've written at various points during the summer, is frustratingly hard to come by.
