Hi walia45,
Many of MBA/Master degree students who apply for study permit to Canada, are not eligible/ qualified/competitive enough to get admission into masters/ PHD at Canadian universities. IF YOU GET QUALIFIED FOR MASTER'S /PHD, THEN VERY WELL..BUT IN-CASE YOU DON'T, The best bet would be to apply for a background related (in your case management) 1 YEAR POST GRAD DIPLOMA courses in various colleges across Canada, primarily located in ONTARIO, offering 1 year post graduate Ontario certificate. This would also make you eligible for getting 1 year post graduate work permit.
Best of luck!
