Ferries spokeswoman Deborah Marshall said health officials would issue a public notice if they believe wide public exposure has occurred. No such alert has been issued to date.
The ferry service implemented a mandatory mask policy for passengers and staff at all terminals and on all ships on Monday.
Early reports from ferry staff indicate that passengers across the fleet are on compliance.
“We are hearing positive things about this mandatory requirement,” spokeswoman Tessa Humphries said on Monday. “We hear from terminals a compliance rate of about 90 to 95 percent, and that’s halfway through the first day. ”
Any passenger who does not comply with the face protection requirement may be refused the day’s trip.
