More details are expected today after a plane crash near Fort Smith, Northwest Territories yesterday.

There were fatalities but the coroner’s service has provided few details.

A mining company - Rio Tinto - said that a number of its staff were on the plane, which could carry up to 19 passengers.

The plane took off from Fort Smith yesterday morning, near the Alberta border.

Meanwhile, RCMP, the BC Coroners Service and the Transportation Safety Board are investigating a helicopter crash near Terrace.

Three helicopters were running a heliskiing operation in the mountainous back country with numerous people on board each.

Communication was lost with one of the helicopters and a crash site was located in a snow field.

There were seven people on board - three people died. Italian media report them as being Italian nationals - and experienced Heli skiers.

The other two helicopters shuttled the remaining four passengers from the site to where they were met by BC Ambulance and taken to hospital with serious injuries.
