Hi,
I am going to be very blunt here, it does not sound like you have any intention to move outside of Quebec. In order to convince the officer you will need concrete evidence that you are planning on leaving Quebec, such as a job in another province, a lease in another province, evidence of strong ties to another province or evidence that you are leaving your job. If you are planning on living/working in Montreal you MUST apply through the Quebec immigration route - the CIC is very strict on this matter.
