The major system here would be the registry per se. It is obviously a registry that has been built up over many years. During that process, the level of documentation and the rigour applied to the issuance of the social insurance number has changed dramatically over the last 30 or 40 years. So the point we were trying to make is that the integrity of that register has to be strengthened. There was a discrepancy between the numbers in the registry and the population. There can be very valid reasons for that, but the department should be able to explain what those are. The number did seem high at the time, at five million.
There were also issues with social insurance numbers that had been issued pre-1976, when there wasn't a lot of documentation required for their issuance. I remember, too, there was a question with the temporary social insurance number, because sometimes people could come in for temporary work permits and get temporary social insurance numbers—the 900-series—but there was no expiry date.
There was even a question with some numbers that, I think, they said were cancelled or were not to be used, but which could still be used in the system. The system hadn't deactivated them totally.
