I recommend the University of Manitoba for immigrants interested in engineering. For technologists, or those interested in doing a short-term course, there is Red River College or Winnipeg Technical College.
There is a lot of scope in various fields in Canada. Basically, if you believe in yourself and make use of the opportunities available, you will succeed.
Note: Although Bala chose to pursue post-graduate studies, you only need an undergraduate degree to earn a P. Eng designation.
