Canada Visa

It is either a Diploma or a graduate certificate. Entry requirement for Diploma courses in Canada is 6 bands with not less than 5.5 in any module and class 12th passed.
Entry requirement for graduate certificate in Canada is 6.5 bands with not less than 6 in any module and a 3 years Bachelor degree.

You can choose many subjects as per your interests,but you should first mention your stream in graduation to help you further in the same.

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.

Your marks should be more than 60% in class 12th and IELTS band 6.0 to 6.5. Marks should not be less than 50% in any subject.

I am sorry to say this, it will surely effect your visa process and to be honest there are only 10% chances of visa approval.

Hi Arjun, you do not need work experience. The co-op program itself will provide you work experience while studying. The supplementary application form is more of a personal statement through which you must showcase your motivation, skills, achievements and so on. For fee structure please visit the program website, you must keep checking the website for the new fee structure

You can write to the university of your choice as every university has a different policy concerning backlogs. So we can't provide any generic answer as it depends from university to university.

Hi Himanshu,
A first class is recommended. To get into a good university a score of 75% and above is required. Admission cut-offs varies with universities, you must check separately. Do remember that you must have received the admission offer from a college or university before you can apply for the student visa.

There is no average salary figures anyone can provide you. The reason being that the kind of job you will get after finishing the course will depend on how good or bad you are at your course.
You can check the college's website here to get more information.
