I am aware about your case Sandhu.
See, SPP is not for you or broadly for any one whose aim is sound education, recognized throughout Canada!
Your case is different as you are already a MBA. For you things would depend upon Work Experience and the course you select to study in Canada.
So, the first step would be to take GMAT and score 650 upwards. Very important. Second would be Work Experience of at least 2 years to get into a good B School in Canada. Then build your SOP around it. This would be the Ideal Case.
Shortcut would be, score really well in GMAT, around 700. Apply to Simon Fraser, Victoria...2 Very Good Universities which take aspirants without work Experience if their profile is overall Very Good.
All the Best and feel free to ask any number of questions till we all finally figure out best for you. Enfield is another member here who has good knowledge about B Schools, he will help you too.
Start a Thread for you and we will keep discussing how things are going for you!
