The COVID-19 Public Health Response Act, first drafted in April 2020, is a very significant piece of legislation in our COVID-19 response. At the time that particular Act was put into place, we did not know how long we would be dealing with the pandemic, and there were a lot of things that we didn't still know—at that point—about the pandemic. As the year has evolved—or the year and a bit—since that was passed, we have, of course, found out a lot more about COVID-19, about the sorts of measures that we need to take in order to be able to respond to it, the sorts of risks that we are dealing with, and the sorts of measures that we might need to have in place to be successful in our future response to COVID-19.
