I'll give you a bit of a long answer, as short as possible.
The worst consequence, I would say, would be that under the Privacy Act regime the treatment time of complaints is growing because of limited capacity. That said, we closed more files last year than we received so the backlog has decreased in the last year. But treatment time has increased to something like nine months, which we think is too long and we want to address it.
Under PIPEDA, the number of complaints has risen by roughly 50%, and through a number of means we have been largely successful in meeting the demand.
