Not all programs require you to find a supervisor prior to applications but some do. Where do you start? Right here. Research (thesis-based) graduate programs do require that you have a supervisor whereas most professional Master's programs do not require students to have a supervisor. If you're not sure, reach out to our School of Graduate Studies and they can help guide you. A good place to start is browse some of our great researchers and their projects - perhaps you'll find a perfect fit for you... and if you do - simply send an email to that professor and ask them if they are accepting students. You'll never know unless you ask.
