“Although all COVID-19 health and safety protocols and precautions were observed before, during and after the flight, there remains a risk to deployed personnel,” the statement said.
The flight stopped overnight at Canadian Forces Base Goose Bay, Newfoundland and Labrador, on August 24, and all crew and passengers remained in isolated accommodation on the base.
The department said base staff, including bus drivers and people delivering meals, followed public health guidelines such as the use of personal protective equipment and physical distancing.
He added that while the risk of exposure in the isolated area where passengers have stayed is low, some staff are self-isolating as a precaution.
“The wing has been in contact with public health and is in the process of seeking contacts,” the statement said.
Members of the armed forces who have tested positive for COVID-19 are currently under observation and remain in isolation at CFB Trenton in Ontario.
All passengers and crew on the flight have been tested for COVID-19, the department said.
Those who tested negative are either in quarantine at CFB Trenton or in self-isolation at home.
Newfoundland and Labrador currently has an active case of COVID-19, which was reported on Friday after the province went more than two weeks without a new case.
Public health officials said the case involved a woman under the age of 19 who recently returned from Asia.
