CBC News learned Friday that the charges against Ornge were officially laid Thursday by the federal Ministry of Labour.
- LISTEN | Investigators hand down 7 directions to Ornge
Liberal Leader Kathleen Wynne noted at a rally Saturday while campaigning for the June 12 provincial election that she had attended a memorial for the four Ornge victims.
When asked by reporters to comment on whether the Ontario government failed to provide appropriate oversight of Ornge, Wynne would only say: "Today marks the human tragedy of that accident ... My thoughts are with the family today.
"There is a case before the courts and I can’t comment any further on the charges."
She added: "There are many, many changes that have been made at Ornge over the last couple of years and we will continue to monitor the operations obviously very, very closely."
The four killed on May 31, 2013, were:- Don Filliter, 54, the crew's captain, of Skead, Ont.
- First Officer Jacques Dupuy, 43, of Otterburn-Park, Que.
- Paramedic Dustin Dagenais, 34, of Moose Factory, Ont.
- Paramedic Chris Snowball, 38, of Burlington, Ont.
The Sikorsky S-76A helicopter they were travelling in crashed one kilometre from an airport in Moosonee after taking off in the early-morning hours.
Document alleges inadequate training
The four were en route to picking up a patient on the Attawapiskat First Nation reserve in northern Ontario, and were flying in darkness at the time of the crash.
A court document obtained by CBC News reveals that many of the charges relate directly to sections of the Canada Labour Code that govern green pilots operating aircraft together.
The document alleges that Ornge permitted the pilots to fly the S-76A helicopter "without adequate training in the operation of that specific aircraft," failed to provide the pilots with "a means to enable them to maintain visual reference while operating at night," and that Filliter had "insufficient experience in night operations."
Filliter's pilot proficiency check in the helicopter was incomplete at the time of the crash, according to the charges laid out in the document, and in allowing Filliter and his Dupuy to fly together, Ornge violated its own "green-on-green" pilot policy.
The embattled air ambulance service has also been charged with failure to ensure employee safety resulting in the death of the two pilots and failure to ensure that supervisors and managers had knowledge of the Canada Labour Code.
Ornge reviewing charges
In October last year, it was revealed that officials at the company were warned by a safety officer at the base in Moosonee that the combination of inexperienced pilots and nighttime operations would likely result in a fatal accident.
"Ornge confirms it has received a summons with respect to charges laid in connection with the accident under the Canada Labour Code’s occupational health and safety provisions," reads a statement provided by the company to CBC News.
"Ornge is currently reviewing this documentation, and we cannot comment further as this matter is before the courts."
In November, investigators from Transport Canada handed down seven directions to Ornge following its investigation into the Moosonee crash.
The company was ordered to comply with the directions by May 31, 2014.
News of the charges comes amid an ongoing Ontario Provincial Police criminal investigation into the alleged mishandling of government funds by the company's top officials.
