The best way I can answer that question is to use my own home service as an example.
We have seconded local police officers to an integrated unit, led by the RCMP, to manage those quarantine situations in the province of British Columbia. I believe, although I'm not a 100% sure, the same thing has happened in every province. That is how the government, through the RCMP, is making sure that the information is known to local agencies. That integrated unit or secondment unit will communicate out to the different police services about where there are people quarantined as a result of travel and that kind of thing.
