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.

Yes, you are eligible. First you need to appear in two exam i.e. IELTS/TOEFL and GRE. In Canada, GRE is not mandatory but it will increase your chances of getting admission.

You can not study in Canada with 2.3 GPA because even the low ranking universities, institutions in Canada require a minimum of 2.7-3 GPA and 7.0 IELTS scores for admission.

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. Also, security jobs are not so good in Canada because all the things are very expensive there.

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.

Hello Sangita,
It depends on many factors such as Company's reputation, Type of Job and many more. However, on an average you can expect salary between 60,000-70,000 Canadian $ per annum.

With 51%, it's going to be so tough. I would suggest you to look into Australian colleges. Universities in Canada are very competitive. Of course, you can apply for a visa but chances are minimal.

NWAC is recognized by MHRD and AIU both. So, there should not be any issue. Just to ensure the equivalence with Canadian universities. You may write to them directly with your transcripts.
