Pre-MBA Experience for IB (Toronto)

Hi,

I am an engineer with 4 years of experience. I have implemented big systems, capital projects and managed 20+ people teams. I am considering a career switch into IB. I am in Toronto and already got admitted to York.

1. how competitive will i be after obtaining my MBA plus 4 years of engineering experience?
2. i am planning to be involved in the finance club at York and expand my network in the finance industry. What else would you suggest i should do to be more sellable?
3. any insights?

I know a very similar thread has been posted but i would like to get a view about the Toronto region
