Are you aware that you will not qualify for a Post Graduate Work Permit if you attend the Toronto Film School? Since this is a private school, it does not qualify for a PGWP. If you plan to return home after finishing your studies in Canada - then you'll be fine. If you want to remain in Canada and work after you finish your studies - and qualify for permanent residency - then you need to pick a different school.
Aside from what @scylla posted, for a study permit application, you should focus on home ties and financial capabilities and explanations why you want to study in a film school and its relations to your past work experiences if any. But what Scylla has posted, if you have any future plans in Canada, i would suggest studying a different program and school.
No - it's not that easy. Your employer has to obtain an approved LMIA in order for you to qualify for a work permit. You should assume it won't be possible to find an employer willing to go through the LMIA process since it is very long and expensive with no guarantee of approval.
