Yes, there is movement! I got off the waitlist for the Vancouver cohort on Monday, June 15th around 330 pm as well. I received my waitlist email on April 21st. For anyone still on the waitlist, don't give up hope!
Congrats to everyone who got acceptance emails! I have not heard back from UBC at all and am following everyone's posts. At this point, I'm hoping to make the waiting list --unless those emails have gone out already too.
