I'm guessing on possible parameters what specifically determine an application speed to be processed at:
-Immigration history, prohibitions, rcmp and security clearances, for sure
-Your First, Middle, Last Name [some names flag up and may trigger the system(s) to dig deep down]
-Number of addresses you have been living at
-Type of addresses you have been living at
-Number of international travels (specifically after becoming PR)
-Physical presence (or absences)
-CRA history, taxes paid etc
-Past / present professional history
-Job / occupation nature
-Single / family
- ......... etc
