I will direct the question also to my colleagues here, but just to start in terms of the compliance piece specifically, we have a way to really promote compliance by having a clear communication package for anyone who is coming in through travel—borders and so on. The enforcement piece is also directed to gradually move people to a regime whereby they are self-directed to make the right kind of call.
For example, if you are a person who has come in and we need a day eight test done, our email system will generate that. Robocalls will remind the traveller that it is what we need to do, and those aspects in the compliance promotion world allowed us to gain much ground. In cases where we did not really have the ability to connect or get a response, we used the law enforcement agencies and door knocks—and I mentioned more than 540,000 door knocks in terms of that—so the enforcement was there.
I will shift this to Jennifer in terms of any other components, more importantly the ones that included ticketing or other aspects. Jennifer can probably explain a bit more in terms of the other tools we've used.
