ARNPRIOR, ONT. The announcement Wednesday that the United States would be keeping land border crossings closed to Canadians for all non-essential travel until at least Aug. 21 has left at least one border town mayor frustrated and annoyed. Canada announced earlier this week that starting Aug. 9, all fully vaccinated Americans would be able to cross into Canada for any reason once again, but the U.S. is not reciprocating, a move that’s left Prescott Mayor Brett Todd frustrated. “To find out that the Americans are simply not willing to do the same is simply very frustrating and deeply annoying, quite frankly,” said Prescott, Ont. mayor Brett Todd.
