Hi Vjr. I am an integration Specialist, not an Immigration Specialist. I deal with the process of managing transitions to Montreal from other countries … other than the immigration legalities. Immigration issues, particularly where Quebec is involved, are bizarrely complex and need to be dealt with through an immigration attorney. Having said that, it’s most likely correct that if you have a CSQ (Cerificat de Selection de Quebec) you will probably need to process the PR in Montreal. If you don’t have a CSQ, you are most likely better off to have your PR formalities processed in Toronto, it would let you fly under the radar of Quebec Immigration. You will be free to relocate to Montreal at will once you have PR status recorded and can then register in Quebec for Social Insurance, RAMQ (Health Care), Driver’s License, etc., and be employed in Quebec. This simply allows you to enter through a different, and less bureaucratic, door, but the end result is the same.
I assume the residential address you record on entry is not critical at that point, but I don’t know that for a fact. Sorry I can’t be more specific. Hope this helps.
