When we rolled out the temporary resident biometrics project in 2013, we weren't applying it to all countries, so only certain countries were chosen. This time it will be a more global application. It won't be certain countries on the list and others not on the list. We likely would not go live with every country on day one just for logistical reasons. Even with just the 30 countries, we started in our hemisphere first for a month and then moved east from there, just to make sure that everything was functioning properly.
There's a lot of equipment that will need to be put in place at visa application centres around the world. We expect a global rollout in 2018-19 for all remaining countries, not just some. While not all countries would go live on day one, we suspect that it would be a fairly quick implementation, perhaps region by region. It will depend on the logistics at the time and on what's easiest for the system to handle, and then we would slowly ramp up to full enrolment from all remaining countries soon thereafter.
