I'll start with the general perspective.
First of all, this act won't repeat what we're doing now because we're not doing anything about security with the actual legislation. All of the provisions in the legislation in front of you regarding security are new, and we think these are gaps that need to be closed.
On the security clearance and the complaints you have received from private companies, you would have to clarify a bit for me what kinds of complaints you got. Are these companies trying to do business with the Government of Canada, or are these companies trying to do business with ports or airports? We definitely wouldn't want to implement security clearance requirements where they're not required for security reasons. First and foremost, we would base all of that on a solid risk analysis. That's outside of the cross-border issue, which was discussed at length in the first hour.
On the safety side, we are trying to clarify some portions of the act. I'll let Peter or Marie-France clarify those.
