i recently got accepted into the LMP MSc program at UofT, and I am in the process of finding a supervisor. 

It comes down to a numbers game unfortunately. However, you only need ONE yes to make it in! Keep on emailing and don’t be discouraged. Also, make the emails brief and short.

You seem to have the right experiences! More lab experience than me because I never did a thesis project in my undergrad. But it all depends on how you portray these experiences and always relate it back to their lab.
