<p>To be honest: All of these universities are fine. Just like many universities. If you plan on getting an MBA in the States, there are many many things that will be more relevant.
Namely:
- the job/company you worked at before applying to the MBA program
- your experience
- professional connections
- college preparation/GPA/class rigor (which you be able to receive at any given institution of the ones you listed
- convincing recommendations
- convincing interviews
- and good test scores (if applicable)</p>
<p>Just go to a university where you will be able to perform excellently and that offers you enough access to the opportunities you want to take advantage of.
(-> internships for example, but London, Toronto, and Montreal will all offer you countless intership options :))</p>
<p>Good luck!</p>
