In terms of the number of tests that have been deployed, we'd have to defer to our colleagues at Health Canada and the Public Health Agency of Canada.
I could note that from a Transport Canada perspective, we saw that the restrictions at the border, obviously at the outset of the pandemic, were very effective in limiting the importation of COVID-19. We are, as I've noted, working with our partners to look at what measures could be put in place to reduce or change some of those border restrictions, in particular via testing. The pilot projects are a great example of gathering evidence to support, perhaps, a national program of testing as an alternative to quarantine. Ultimately, it will be our colleagues in the health sector who will make decisions about which tests are used, when to apply them and how to apply them.
Again, I think we play a really important role from a facilitation point of view. We've done some work with airports to look at what a testing regime would look like logistically and how you would set it up in your airport, for example. We've developed what is called an “operational plan” to support that, if and when a decision for testing is made. We've worked with the International Civil Aviation Organization and other international partners to look at some of the international standards or best practices for a testing regime, if we go down that path.
Again, as I've suggested, we've been working with domestic partners like the Calgary airport and the Vancouver airport as well as the airlines to help them set up the testing pilot projects that are being led by our health colleagues.
