Sure. There are a couple of reasons.
As I said, part of the reason we did the pilot projects was to test the concept to see how it worked. We learned a lot of value from the specific project we did in Ontario, but also that some of the benefits in efficiencies can also be achieved through technology. It's important to look at what we can do through existing technology, what might require infrastructure changes that are fairly complicated, because you can speed up traffic moving to a bridge through pre-clearance, but ultimately if the infrastructure at that bridge is limited, there's a limited amount you can do in moving traffic quickly.
The other point is that we don't now have the authority to implement cargo pre-clearance under the current act. Those were pilot projects. Again, we require the legislation to move forward with cargo pre-clearance.
