In recent years, certified copies from banks are not well recognized anymore.
You can go to City of Ottawa / Hull, where they should have this kind of services - $10 - $20 per copy? (Sorry, I couldn't remember the details) Or, you can find a lawyer to do so... For "free of charge", you may need to find your local area's MP office...
But, it doesn't hurt if you ask your school to see if they accept certified copies from bank or not, which may be the most convenient way...
