Try doing the following questionnaire:

I don't think you are eligible for a PGWP (Post Graduate Work Permit) since you did not study in Canada. Also my understanding is that you worked as a baker after graduation for a year. In order to apply for PGWP you need to apply within 90 days of receiving your degree.
