A pilot and an Alberta government biologist were killed after a helicopter crashed north of Fort McMurray on Wednesday morning.
The woman worked for Alberta Environment and Sustainable Resource Development (ESRD).
A male ESRD biologist also in the helicopter was taken to hospital in Fort McMurray where he is listed in stable condition.
Premier Alison Redford and ESRD Minister Diana McQueen offered their condolences in a news release sent Wednesday evening.
"I offer my deepest sympathies to the families involved in this tragic event," Redford said.
"The loss of a family member, coworker or friend is truly one of life’s biggest challenges, and I hope that those close to the individuals find comfort in friends and loved ones during this difficult time."
McQueen confirmed that the biologist who survived suffered significant injuries.
"I wish him a speedy and full recovery," she said.
The male pilot was flying a helicopter owned by Aurora Helicopters Ltd. Company president Michael Morin told the Canadian Press that the helicopter went down around 11 a.m.
"We are deeply saddened by this event and feel the loss greatly," he said.
RCMP were called about the crash approximately 128 kilometres north of Fort McMurray shortly after 12:15 p.m.
Investigators from the Transportation Safety Board are now travelling to the crash site.
