In your case, indeed the progression of study is all scattered. You have completed M.COM (so of course you have studied B.COM, hence commerce stream all the way). But then you pursued LLB, correct me if I am wrong, you could pursue LLM, right?
It's not a bad idea for you to apply for CAIPS notes first (where the same VO will explain the exact reason of rejection). The rejection letter you have received is quite generic and is handed out to all the rejected cases. The fee will be 40 CAD for CAIPS and usually takes a month. But it's worth waiting for it. Now, one thing that you and others applying for Para-legal can work on is - whatever course in Law you pursue, laws will be based on country to country basis. In India, you will study IPC etc etc. Here when you pursue a course say in Ontario, you will learn the laws of here not India. So what they might think most likely the students will end up settling here. A good idea is to establish a reason for you to return to your home country. If i were you, I would talk about many LPO (legal process outsourcing ) companies in India which caters to Canadian, american, british etc market where I will have a better opportunity to grab a good position. Also, one can talk about MNCs, there are plenty of Canadian, American companies with their setup in India and handle their domestic and international business from the shared services center. So you can mention in your SOP about this booming industry and how you can have an edge at the completion of your program.
Anyway wish you all very best.
Cheers!
