Not all application have to go through CBSA or CSIS. For some applications, the security is passed by IRCC itself based on a wide range of criteria. "The security screening manual states, "IRCC officer's review applications to ensure that the applications are complete to make admissibility and eligibility decisions. When warranted officer's refer applications in accordance with instructions provided in the
security screening manual to CBSA and other screening partners. Taking into consideration all available information, the officer's decide whether or not to issue TRV to PR visas."
If your security can be done based on the available information, and you do not fall under "mandatory screening," especially if your are an inland applicant, it is likely you your security will be passed right along with final review without your application having to go through the formal CBSA / CSIS process. Also when you may have applied for a TRV to come to Canada that info may also be available in the system.
If you fall in the above category, then your VO, the VO priority will be factors that determine how early your application will be processed and a decision willl be made.
Also, you should send a webform and inform IRCC that you are in Canada and also inform your address, even though it is available on file, there is no harm in doing it again. Sometimes it helps!
