Q. I intend to apply to immigrate to Canada via the Quebec application process, which has a different selection system. Once landed, am I limited to residing in Quebec only?
Answer: In principle, if you choose the province of Quebec as a destination, you do have to have an intent to live and work in Quebec. This will be tested at the interview stage.
If it turns out that the intended destination you selected in Canada is not favourable to you upon your landing, then you are free to move to any other location in any province of Canada.
Once in Canada, you have freedom of movement that is guaranteed to you in the Canadian Charter of Rights and Freedoms.
More specifically, as described in Section 6, of the Canadian Charter of Rights and Freedoms, it is stated:
Every citizen of Canada and every person who has the status of a permanent resident of Canada has the right: (a) to move to and take up residence in any province; and (b) to pursue the gaining of a livelihood in any province.
