Essentially, if an individual wishes to come to Canada under the new regime and they're visa-exempt, with the ETA we will be required to have a record. They will be required to provide us with their information so we can do an initial screen before they arrive in Canada, regardless of the country they have applied from. It will have to do with their nationality and the passport they carry. If we are at that time made aware of any issues, as I said, they can be referred to the nearest Canadian visa office for a follow-up interview with a CIC officer. That would be to determine whether or not an ETA should be issued, regardless of where they are physically—if they're in transit, or what have you.
From that perspective, being able to manage the flow of travellers to Canada...eventually with the rollout of the ETA with CBSA's interactive advance passenger information system, our ports of entry will know who is coming before they leave the airport their flight originates from. Right now we do get advance passenger information, but it's after the wheels are up. At that point, it's too late to make a board/no board decision. With an ETA, we'll be able to work with airlines to ensure that people who are of concern, who don't possess an ETA, don't actually get on the flight to come to Canada.
