Mr. Chair, I'll go first and then I'll leave some time for Dr. Kochhar.
The purpose of the ticketing regime was really to see national enforcement of quarantine measures across the country, and it was clear from our findings that the Public Health Agency hadn't worked through the cohesive enforcement requirement across the country. You're right that some provinces and territories did not sign on to the Contraventions Act; hence, ticketing could not be done.
When you put in a requirement, you really have to think through monitoring and enforcing. Many tools could have been used, and that is something that needs to be improved to deal with better planning for another health crisis, should one occur.
I'll leave it to Dr. Kochhar to add to that.
