I believe about 500,000 applications have been run through the system. About 93% of those were positive matches. When I say that, I mean that the application comes in with the letter of acceptance. IRCC pings the institution associated with that letter of acceptance, and then they confirm the authenticity of the letter.
In 93% of cases, there was a match confirmed by the institution. Two per cent were not matched, 1% were indicated as cancelled by the DLI and for about 2.7% we received no response from the DLI.
