Again, these questions might be better for CBSA, but I would add very quickly that you have to imagine what an app at the border is going to require. It's built for the Public Health Agency. It has to link into all kinds of different health jurisdictions across Canada. It has to be bilingual. It has to be accessible. Cybersecurity has to be tested. It has to be built across many different layers.
All that infrastructure, all that cloud support and all the actual costs in terms of its release and rolling it out are probably where the costs are associated with it.
