What we do know is that we are receiving information in a much shorter time frame. As a result, once travellers have entered Canada, we are able to do post-border checks and get information to the travellers much more quickly, so that they can comply with Canada's border measures.
We also have much higher quality information. We are able to follow up more closely with travellers who are subject to border measures. The Auditor General of Canada has acknowledged that this has been greatly improved since the implementation of ArriveCAN and digital information.
