To put a couple of numbers together for you, for the end of 2023, IRCC is projected to receive 223,000 ATIP requests. Of those, it's projected by the OIC that about 6,000 will result in ATIP complaints. Similarly, IRCC's office itself predicts that if 20% of all eligible applicants file an ATIP or privacy request for their information, there would be 775,000 requests by the end of 2024.
The volume is increasing. It will only increase, and it will continue to drain the resources of the OIC.
