Perhaps I could give a little more background in terms of work that has already been undertaken with the Office of the Privacy Commissioner. As we move forward with this initiative—and just to underline, what the budget bill contains are the legislative authorities to be able to put an eTA in place—you're quite right that a lot of the detail will flow through regulation. However, we will have to prepublish regulations that are developed to support the eTA, and there will be a public commentary period to be able to support the advancement of those regulations. Also, working with the Office of the Privacy Commissioner, we will be required to do what's called a privacy impact assessment dealing with many of the issues you've raised regarding collection, use, retention, and disposal of information that is collected through the eTA process.
We've had an initial consultation with the Office of the Privacy Commissioner, and Ms. Welbourne can provide a bit more detail on that. As we move forward with this initiative, officers will of course be guided by the regulations and policy guidelines with regard to how they would operate with the eTA. For the most part—over 90%, as I said—this will be an automated process. When there is adverse information on an individual, no one will be refused an eTA without a face-to-face interview with a Canadian visa officer. They would have the opportunity to present any additional information they might have. Of course, the principles of natural justice would apply through that interview. They would know why they would be refused.
Perhaps I could ask Ms. Welbourne to talk a bit more about privacy.
