Hi escape,
All three of the programs that you mentioned are very comparable in terms of quality of education, school reputation within Canada / Ontario, and attractiveness for employers. McGill as an overall university might have a slight reputational edge over the other two if you look beyond Canada -- it has better name recognition in the US, for example -- but if you're only recruiting in the Toronto area post-graduation, then that won't matter as much. Since these three programs are all on par with each other, I would recommend that you focus instead on the unique features of each school (such as particular faculty or courses, or student organizations) that you're personally drawn to as a way to differentiate between the programs and find the best fit for you.
Good luck! Please feel free to reach out to us on
