BC Ferries had to cancel two round trips on the Kwuna Sunday afternoon (July 27) after a crew member became ill.The sick employee was taken to hospital but there was no qualified worker available on Haida Gwaii to take their place, said Deborah Marshall, BC Ferries's executive director of public affairs.A replacement crew member was flown up from Vancouver and service resumed just before 4 pm, Ms Marshall said. There were approximately 12 vehicles waiting at Alliford Bay and approximately three vehicles waiting at Skidegate during the temporary service outage.BC Ferries chartered a flight to bring the replacement worker up to Haida Gwaii after they were unable to get the employee on the regular Air Canada flight."While it was more expensive than a regular scheduled flight, we knew customers were depending on the service for their travels and we wanted to resume sailings as soon as possible," Ms Marshall said.BC Ferries apologizes for the inconvenience and wishes the employee a speedy recovery, she said.Ms Marshall confirmed that the Kwuna crew had dealt with two off-hour emergency call-outs to transport the ambulance in the days leading up to Sunday's crew crunch. The first was in the early hours of Thursday morning (July 24), while the second one was in the early hours of Sunday morning.BC Ferries responds these emergency call outs on a "best efforts" basis, she said. "If we are unable to get the proper number of crew members together (five employees for the Kwuna) for whatever reason - sick, fatigued or otherwise not fit for duty - we inform BCAS that we are unable to provide the service and Coast Guard is called," she explained.
