Sure. Just to follow up on the previous question, people can submit their advance declaration 72 hours in advance, so it doesn't need to be done on the plane. There is time in advance to do that. Right now it's only in place at Toronto Pearson and Vancouver, but we want to quickly move that to other airports across the country and continue this rollout of technology.
As to the next piece, moving forward, we see ArriveCAN as one element in improving processing at our airports. We need to modernize the Customs Act. We need to move away from customs officers needing to process every passenger. We need to get to a place where there is facial recognition and biometrics, like what you would see in Europe, where you go through the eGate and your picture is taken. You've already been pre-approved, and then you get a go or no-go sign, a green light or a red light. That's where we need to move in terms of border modernization in Canada.
We've been working on this for over a decade, and now is the time. I think we've seen this summer the challenges we have in processing, given we were in this pandemic space with all the different measures that were thrust upon our airports and the tourism industry.
Moving forward, air travel is going to continue to grow. It's going to double by 2040, and we need to be ready. We need to be prepared. I think we only need to look as far as Europe to see how we can do this the right way. I think the CBSA is ready for that, so the next step is our legislation and regulations and moving forward with that.
A big piece of that is ensuring that it's not going to be mandatory; it's going to be voluntary. The people who want to increase their throughput at the gates can do that, and the people who want to use paper and aren't good with technology can do it the old way. I think having that option there is also important.
