processing time description:
Most permanent resident and citizen services use dynamic processing times, which are released weekly based on 's data in the past 6 months; dynamic processing times for temporary residence services (such as study permits, work permits) are estimated based on 's data in the past 8 weeks or 16 weeks.
IRCC measures processing time based on the time it took to process requests for 80% in the past. Processing time begins when IRCC receives the complete application and ends when an immigration officer makes a decision.
IRCC's processing time tells us how long it took to process the most complete application in the past. Processing time starts on the date Immigration Service receives the applicant's complete application and ends when Immigration Service makes a decision. It may vary depending on the number of applications received by Immigration Service. This is for the applicant’s reference only, and the actual processing time shall prevail.
