Tauck is apparently hoping that they can get their Canada trips restarted at the last minute. My September Canadian Maritimes trip now shows a payment due date of August 15, less than a month before the start of our tour. The border is closed until at least July 21 and although the Canadians are makings noises about reopening to vaccinated travelers, nothing definite has been announced (and probably won't be until near July 21 at the earliest). It's all contingent on 75% of Canadians being fully vaccinated with less than 20% vaccinated as of late June. If Canada sees some reluctance to the vaccine, it could be months. I'm sure not booking my flights until there is more certainty.
