What are those tools in particular?
If Alberta says “no way” to the Contraventions Act and continues to do that, this of course puts uniform enforcement at risk and essentially allows an open-door policy for folks coming into Alberta. What then stops them from going to B.C., Ontario, Quebec or anywhere else if they get through Calgary? There's really no point in enforcing anywhere else, if we're not going to enforce it uniformly.
It's really important that Canadians understand the tools the Canadian Public Health Agency is using.
