As of IRCC's 16 September update, processing-time estimates for Nigerian applicants moved again. Study permits rose from nine to ten weeks, visitor visas from 84 to 87 days, and super visas from 44 to 46 days. Work permits held steady at ten weeks.

These are IRCC's published estimates, not guaranteed wait times, and they're revised weekly. Nigeria's estimates changed while several other major applicant countries' figures for the same categories did not. The data shows a Nigeria-specific movement in the published estimate. It doesn't, by itself, tell us what caused it. Separately, Canada is redesigning its immigration system around lower overall intake and changes to permanent-residence selection. This is a separate development from this week's processing-time update. These numbers don't prove the two are connected.

If you have a study permit, visitor visa, or super visa application in progress, plan around the current published estimate rather than the one you were quoted when you applied. If you're weighing your permanent-residence pathway, the broader shift toward selectivity is the more important trend to follow over the coming months.
