Hi! My sister has already got the working holiday visa which needs her to enter Canada until this June 30. So she booked a plane ticket landing in Canada on June 28. Now the problem is that she took the medical exam on June 28, 2016! Does that mean it's validity ends on June 27 this year? Or is it still okay until June 28? As she's seeking to be a preschool caretaker (there's a specific name for this category which I forgot) she needs it during the immigration process, right? She's panicking so hard and trying to get a new med exam but of course it's all booked until her departure. Please help, did anyone have same problem?
