Airbus Helicopters is cold weather testing its new EC175 helicopter in Yellowknife this month.
The helicopter weighs 7.5 tonnes and can hold 16 people plus two pilots.
Once it's on the market, it will mainly be sold to oil companies to transport crews to offshore platforms. It will also be marketed to VIPs and for search and rescue missions.
Flight test engineer Michel Oswald is part of the team testing the EC175 in extreme conditions.
"If this helicopter stays outside for 24 hours and the temperature is going to -40, if we are able to start this helicopter and to go in flight then we have to see a special procedure in order to go in flight into good conditions," he said.
The crew is in Yellowknife for another week, then they'll go on to hot weather testing in Las Vegas, Nev.
