what should i do about my job?

Did you ever sign a form saying you are willing to work more than 8 hours a day? What is your establishment’s “regular” work hours? According to the Canadian laws, you cannot work more than 8 hours unless you had signed an agreement or the regular work hours of your establishment. I remember signing such an agreement when I began working. Also, you are a part time worker. Partime hours are 30 hours or less per week. You are much exceeding this amount. In addition, if you work more than 44 hours per week, this is considered overtime. You should be paid time and half for those excess hours. I suggest you read those labor laws over, find out what you need about the establishment you work for (like the regular work day hours) and then approach them with this information. From what you are saying, it just sounds like they are taking advantage of you.
