There were many adjustments throughout the course of the pandemic. There were 83 different orders in council, to be specific. One of the key ones was moving to a vaccine-differentiated border to require proof of vaccination from people entering Canada. In addition, there were requirements subsequently for testing at the border, and there was a time when the use of the app shifted from being voluntary to being mandatory. Each of the OICs was generally in place for a period of one month. Therefore, they needed to be renewed, and they needed to adapt to the different situations that took place as we had successive waves of COVID-19 and the entry of different variants.
For example, when there were new variants detected globally that we were concerned about that were variants of international concern, we were able to use the app to determine the travel history of those who had entered Canada to advise them to isolate.
