Hi Arsh, this is totally upto an individual what he or she wants to study. There is no strict rule.One can pursue a Masters in the same field, related area or even opt for an MBA. You must follow your interest and know your career plans and then decide the course of study.
Good luck.

Everything is neither easy and also not so hard. They will take your interview that how you speak English perfectly. They will ask some questions to know how you react (are you angry, polite or very quite). If you fail to qualify their interview then your home country is better.

Hello Suresh,
For industrial engineering, Concordia University is the best in terms of reputation, quality of teaching and many more aspects. If you ask me to priorities, then Concordia would be my 1st option, then comes Windsor and finally Dalhousie.
All the best.
