The COVID Alert app is one tool in our tool box, one additional measure we have implemented in an attempt to reach out and increase the number of people who may be aware that they've been unknowingly exposed. It certainly has areas of applicability.
I would like to highlight that this is a relatively new app as well. We are really starting to see increased uptake of it. We're starting to see a value benefit for individuals who are using it, and we are encouraging all who wish to, to use it. It's an interesting tool, because again, it is essentially sort of a social contract. It's people sharing their information in a safe and confidential and anonymous way to help others, so I think of it as a very Canadian approach.
It's one tool, but it's not the only tool.
