There is a huge disparity between the U.S. and Canada with respect to 'reopening'. Virtually all of Canada has reacted recently to the 3rd wave as it did to the 1st wave, for the most part. There is no clear delineation from province to province of when things might re-open. Every province is either making it up as they go along (Ontario and Quebec) or reluctant to say anything (Alberta) for fear of acting too soon.
The optimism in the U.S. appears to be based around the 33+% of the population who are fully vaccinated. However just over 50% of the population has received at least one dose. Neither statistic is anywhere close to the definition of herd immunity yet their case counts have dropped considerably over the last two months. Think about this ... sports stadiums in most states will be able to go to full capacity within weeks
Canada is on par with the U.S with the number of one doses but we are lagging far behind on the number fully vaccinated. We won't catch up until supply of vaccines catches up. Canada seems to have been hit harder (in terms of cases) with the variants compared to the U.S.
Under the headline of 'Please Explain This' .... there are states like Florida who have been 'open' since late last summer. They did not see serious outcomes form either the 2nd or 3rd wave (spring break was right in the middle of it) even though health experts criticized state government for doing so.
All I know is, we all live on the same continent. Although the land border has been closed, air travel between the two countries as well as internationally has been open throughout the pandemic. We still don't know how long the vaccine immunity will last. There are already rumblings of a 3rd booster shot being required after a year from the the first one. Where does that put Canada on the timetable of re-opening and for how long before we see cases ramp up again and we panic?
