Colleges in Canada

Visit their website. In the section for international admissions, you will find the admission form for the college.

To clarify, at US and Canadian universities, there is no course called M.Com degree. Most of the degrees are MS (Masters of science) with business specializations. So you will find a lot of colleges offering courses like MS in Management. The other PG degree in business is MBA. So please mention which of these two options are you looking for.

Most of the good colleges are mainly in Toronto, but as you said to list out colleges in Vancouver, I will list out the colleges which are good for banking and finance:
1. Selkrik
2. Langara
3. Columbia

It is a prestigious university in Canada. I am sorry to say that you are not eligible for the same.

You will fit quite well. Your profile is pretty good.

You should go for IBM, Centennial College is good for this course.

If you are looking for the best colleges in Canada to do mechanical engineering then go for Centennial College - Toronto, Ontario and George Brown College - Toronto, Ontario. Their fees will be around 6-7 lakhs. Moreover try to score 6.5 or above band score in IELTS exam. Best of luck!
