I heard there was an announcement about opening the US/Canada border on June 30

Please note that the shots being provided in the U.S. are NOT vaccines. They are gene therapy. They do NOT prevent anyone from getting the virus nor do the prevent anyone from spreading it. What they do however is reduce or eliminate symptoms of those who do get it.

Regardless of how many people get the shots, it may ultimately make no difference in when the borders are opened or the rules relaxed. Mike's comment is spot on and as elections approach I think Mike's comment will become more and more the case (here in the U.S. too!).
