You can call IRCC and ask about VO. But in reality many factors affect your application, e.g. you nationality or whether there is a hit in a database on your name, both of which can significantly affect the length of security screening for exampleThank you very much!
That means the official expected time is not that valuable for reference. But how do I know my VO and the officer who is checking my profile? because my case is not really complex. I never travelled to another country, had no crime record, and stayed in Canada for a long time. should process fast but the fact is the case is stagnant.
