We are peace officers; we're just not considered peace officers specifically under the Quarantine Act. If someone presents to us and is visibly ill, which is one of the things we're supposed to look at as officers at the border, we don't have any legal authority to detain them. All we can really do is call the police or call the Public Health Agency.
Sometimes we'll get someone on the phone, if there is someone available, and another agency will show up to deal with the traveller. Really, we currently have no ability to stop that person at the border with the powers we have under the Quarantine Act.
