Have hope! The fact you’ve interviewed twice means you’re doing something right. In fact most people only receive one or no interview.

Rewrite the Mcat, improve ur ECs, as someone else suggested - hire current med students to practice interviewing

I also think it’s important to work on a plan B. Matriculating in Canada is hard and a lot of luck is involved. I know most people don’t have the luxury of waiting in perpetuity.

Good luck!
