I have to admit that I'm not fully briefed on that initiative. I do know that in other countries where it's been used, and I'd assume it would be a similar sort of process in Canada, it's a way of establishing and verifying someone's identity before they get onto an aircraft or before they arrive at a port of entry. Then, if there are some concerns, that individual can be referred to a visa office, or their file or application can be looked at in more detail. Any concerns or issues can be resolved before the individual appears at Canada's border.
