Just clarifying some terms first:
The city you land first is called as the Port of Entry (POE) in Canada.
The city you intend to live is called as the Destination City (as listed in CoPR).
As an FSW or PNP applicant, it is not a requirement to directly land in the Destination City. At the POE, the CBSA (Immigration Officer or the Border Services Officer (BSO)) will ensure admissibility, including verifying the truthfulness of your (applicant’s) intentions to reside in the province that has sponsored you.
Once you become a PR, Canada gives you the following rights in Section 6 of the Canadian Charter of Rights and Freedoms:
- to move to and take up residence in any province; and
- to pursue the gaining of a livelihood in any province.
So, technically according to the Charter, once admitted as a PR at the POE, there is nothing that can come in between you and the Charter mobility right to live and work anywhere in Canada.
(Important for PNP) However, there is something called as the Immigration Act under which come the power for Provinces to invite foreign nationals to come to their Province. This is in the
Immigration and Refugee Protection Regulations (IRPR). If the Border Services Officer (BSO) at the POE during the time of landing receives any indication that the PNP applicant does not intend to reside in the Province that has nominated him/her, then they are reported under the section A44(1) for non-compliance with paragraph 87(2)(b) of the IRPR.
What this means is that the PNP applicant will be offered if they want to voluntarily withdraw their PNP PR application, and their CoPR is seized and informed to IRCC. The 2nd option is for the PNP applicant to ask for further examination - in which case they are allowed into Canada, but will be examined by IRCC inland office, and even in this case the CoPR will be seized.
In Summary, your conversation at the POE with the BSO is very important. While the Charter offers you a Right, the Immigration Act also is a legal obligation with your sponsoring Province, and you need to play your cards carefully.
