Employer requiring my SIN number
I am an international student with a vaid study permit which let me work up to 20 hours per week and my intentions are to apply for the PR after my graduation. Recently I started to work for a worker recruiter agency for occasional job. After my first day of job, I was required to give my SIN number and copy of passport in order to receive my first cheque. I have not received any written contract and I realized that several illegal workers were working for this same agency. I am concerned to give my SIN and ID, as they could use them for register other illegal immigrants and at the end, it could seem that I worked more than 20 hours per week during my stay in Canada, what should I do? My employer told me that if I dont provide him with this information my payment won´t be processed and I really need the money.
