Le Cordon Bleu is the best Culinary Arts school in Ottawa. Of couse the best Le Cordon Bleu is still located in Paris. It is a private school so no government assistant. (which mean no OSAP)
I am not sure about the renting market in Ottawa, given that Le Cordon Bleu is located in the heart of downtown the rent must be higher and hard to find this time of year.
Well, part time work is really depend on your ability and experience. If you are willing to start as the bottom most hotel and restaurant will be more than willing to offer you a position.
Good luck.
