If you are looking for PR not a career in your field, you can go for any famous programme from colleges in Canada (not from University).

As at your question you have done MBA, so doing Diploma is worthless after than, but you have mentioned Canada, it means PR could be a reason, yes, you can go for any college not University.

Hello Tanmay,
You are interested in management in the IT sector, my suggestion is BCA+MBA because you save 1 year in career.
2nd thing, you can do B.Tech and do job for 2-3 years, then go for MBA in IT. It is also a good option. Think and decide.

Both Business schools are good option. If you are comparing with WE Mumbai campus, then WE is better option but you are comparing with WE Bangalore campus so N L Dalmia is better on terms of ROI. N L Dalmia has lower fees and better ROI.

Yes sure. Your CMAT percentile is decent. So, you have good chance to get a call for next round.
All the best.
