That will be difficult for you to do - if not impossible. In another post you mentioned that you already have a law degree. If that's the case, CIC will expect you to apply for a post graduate work permit, another bachelors degree or a masters. To the best of my knowledge, all of these will cost you more than $10K in tuition which will push you well over $20K after living expenses and travel expenses. If you apply for a different / cheaper course or a cheap/private school, your chances of being refused for the study visa will be extremely high since your planned education in Canada won't make sense in light of your previous education / experience.
You have to pick a courses that makes sense / matches with your previous education / experience. You can't just pick a random course because it's cheap. If you pick a random course then expect your study visa to be refused.
