Unlikely to get a post secondary teaching job with a bachelors degree. Many provinces require a teaching English as a second language diploma to teach new Canadians although in Quebec the teaching would be in French. I would look at the teaching criteria for each province in Canada. Most require a masters degree. There is also a surplus of teachers in many regions. Quebec is probably not ideal given your past employment. Not sure if you speak French but that also makes getting a job more challenging.
