JaxDad -- yes, you say the particulars of these border openings so much better than I do. There is a "US Embassy and Consulates in Canada Fact Sheet" (use those words on Google) which will appear on the internet from the State Department to indicate what we have discussed. I am computer challenged at managing links. However, this news is so new that the Dept of State may not, as yet, amended the Fact Sheet. As more details become available from reliable sources, would you help add those to the list? By the way, the answer is "FDA or WHO."
