Thank you, Minister. I would echo that last comment on not-for-profits across this country. There is amazing leadership on the ground at the grassroots. It's what's needed, and we know we'll get more of that as we go through this terrible pandemic.
I have one last question.
The government launched a national exposure notification app. My home province of Nova Scotia has joined the platform, as well as the rest of the Atlantic bubble. I personally downloaded the app and have been encouraging my constituents to download the app as well.
A lot of people, though, Minister, have questions around some of the language used to explain how the app works. Could you explain for Canadians the difference between exposure notification and contact tracing? I guess the last question would be, why did you choose this model, or why did the department and you choose this model?
