This amendment is designed to limit the retention of information to 99 years. In the United States, the limit is 76 years. In Canada, there is no limit at this time. The idea is to retain the data so that, if an offence is committed in 15 or 20 years, information is available to determine whether a specific person crossed the border at a specific time on a specific date. We suggest a limit of 99 years because that is roughly a person's life span.
