Hi HN19,
Post these same questions to the admissions team of each school you are targeting. I did the same and got some very insightful responses with detailed scenario at each school. Every school and city has their pros and cons, so they'll be best able to comment on questions, esp. coming from international students (since MPP/MPA) has a slim international prospective student pool anyways. Having said so, my 2 cents on your questions based on the responses I received from schools - a) No, absolutely never a case (however in most programs the majority chunk is directly from undergrad or grad, with workexp pool seen in some like the recently opened Max Bell at McGill and Western MPA b) No, and yes (Canadians, not experience - for Federal jobs) c) You would be the best person to answer this since it really depends on your aspirations. Both Munk MPP and MGA are good and expensive as well, check theri curriculum may be d) May be, I havent given it a thought, I am an older applicant so wouldnt take them anyways hehe e) Admissions team again (but yeah, holistic - your degrees and workex would probably help you here)
I am an aspirant from India too btw, but I plan to apply after my PR which is probably due in few months. I will apply and if my PR comes through before classes start, I (and my tuition) would become domestic - that's what all the adcoms said.
All the best!
