I have received admits from Rotman, Schulich, Ivey, queens and Mcgill. Which one would be the most suitable. Also if you can rank them in an order. My post MBA goal is to rise up through the ranks of admissions director at one of the prominent b schools

An MBA does not fit with your careers goal. Have you looked at the profiles of such people? 

yes MBA graduates have gone on to become executive director admissions of the mba programs etc. Alternatively I want to start up my own admissions consulting firm.  I do have prior experience in the field as well as placing students into b schools such as st Gallen with 100% scholarship, LBS, IE, ESSEC, SMU etc.

Yoga teachers have gone on to become directors of MBA admissions too, that's not the point. Most MBA admissions leaders have advanced degrees, but they tend to be in career counselling, education, organizational development or the humanities rather than MBAs. A minority have MBAs, and a minority of those has top-tier MBAs. 

If you want to run an MBA admissions firm then, totally, do an MBA because most applicants mistakenly assume that an MBA is the best qualification for such work. However,  it takes only a trivial glance at admissions director's profiles to see that these are people with an education that is focussed on transferrable soft skills homes in a non-profit or HR setting. 

that's a point well made but it would be wrong to say only a minority and those from top tier go on to pursue a career in this field. My goals have been shaped after seeing many MBA or Msc Management graduates moving into such roles

You are simply mistaken, and it's so easy to show that you are wrong that I even wonder why I am replying to you.  I literally worked my way through the profiles of a large number of such people and made a calculation. Less than half of the admission directors at top US and European less schools have MBAs, and most of those do not have top-tier MBAs. 

Only if you were humble as you are knowledgeable apparently you would know why you replied to the post

Shrawan, don't ask questions on a discussion board if you won't want an answer. If you just want to be told you are making the right choice, ask a friend. 

In this case, Stuart describes the objective reality: Most admissions managers at the prominent business schools do not have MBAs, and if they do they are rarely from those schools. You have said he is wrong but, no, anyone can see Stuart is right and it makes no sense to say he is wrong when it's so easy to read their profiles and see he is right. 

You criticize Stuart for not being humble. In fact you should be thanking him for taking the time to answer your question and correct your mistaken understanding.
