Incorrect. FP letter clearly states to have them sent to IRCC Vancouver. My mom had that as well. @andrewcwilliams is correct.That is not correct. If you have FP Letter, it clearly mentions for destination CPC Sydney, NS
It is the only address RCMP sends FP results to.
The letter asks us to tell the FP agency to send it to the specific address of IRCC Vancouver. It also says that the application will remain in your local citizenship office which will probably be Sydney, NS until the CIO (Centralized Intake Office) at Sydney, NS decides to distribute the applications accordingly. My guess is that you would know the processing office location if it changed when you get your test invitation or if you ask for the GCMS notes and it documents the file transfer.
