Hi Faizi,
I am really sorry to hear about your experience. Believe it or not, this is the most common reason for the visa rejections of most of the applicants of student permit. Therefore, while submitting your Visa application, utmost care should be taken to show strong ties with your native country in order to satisfy the VOs that you'll have enough reasons to come back to your native country after completing your studies. In order to make that impression, try to show evidences of movable and immovable assets (real estate, automobiles etc.) in your and / or your parent's possession, liquid and long-term deposits (FDs, cash statement, shares, bonds, debentures etc.).
In addition to it, your area of study should align with your past education, work experience and future goals (how you'd like to use your degree).
I had also suffered two rejections from embassy in Oct and Nov ' 2016. I understand how rejections feel. So, I encourage every fellow applicant to incorporate these points (in addition to many others) while selecting your area of study and filing Visa
Recently, I have come out successful in my MBA application at 2 Universities (SFU and University of Alberta). Also, my Visa Application is approved on 20th Jan for Sept intake (I know it has been very earlier that I applied, but I wanted to avoid the application rush because the Canadian embassy is due to experience huge no. of applications this year because of changing immigration policy of US)
In case you need any further help, pm me or connect on WhatsApp at +91 9435721767 -I will be happy to help.
I have applied for Sept 17 intake, hope to meet you all guys in Canada.
Best of Luck,
