Passengers of the crashed Air Canada Flight AC624 are in the process of filing a class-action lawsuit, a Nova Scotia law firm confirmed.

MacGillivray Injury and Insurance Law say they have consulted with passengers on a lawsuit which would likely target Air Canada, the Halifax Stanfield International Airport, and Nav Canada, which owns and operates Canada's civil air navigation system.

The lawsuit would be filed with the Supreme Court of Nova Scotia, seeking damages for any physical and psychological trauma suffered during the crash landing.

Vancouver aviation lawyer J.J. Camp told CTV News Channel Tuesday that airlines generally don't have a cap on the amount a passenger can receive in a liability claim, adding there are potential psychological damages that can arise after the crash that could be taken into consideration.

"That's not the end of the story," Camp said. "The post-traumatic stress symptoms and the PTSD fallout can be much, much more severe than the physical injuries."

Camp said he believes the passengers have a case, adding lawyers will need to determine the condition of the airplane and the state of the pilots at the time of the crash, as well as the effectiveness of the airline, Nav Canada and the airport.

"(Nav Canada) has an obligation to keep the pilots fully informed of on-ground weather conditions that prevailed at the time of the crash landing," he said.

"Looking at the Halifax International Airport Authority, and whether they were up to snuff with their instruments that guided the aircraft in, and whether they had proper lighting, and whether they were performing according to proper standards."

Following the crash, which occurred early Sunday morning, passengers evacuated the plane and huddled on the dark, snowy Halifax airport runway.

Passenger Steve Dijkema, who began capturing the scene on video moments after climbing out of the plane, told CTV News nearly half the passengers he saw were "bleeding from their face, some profusely."

Dijkema's footage shows some passengers shouting, while others are seen shivering, wearing little more than a T-shirt. One man presses an airplane pillow against his bleeding face.

Dijkema’s wife Sarah remembers passengers trying to get a safe distance from the crashed aircraft.

"Once we got off, I remember Steve just grabbing me by the shirt and like hauling me away, like run as far away from the plane as you can get," she said.

Passengers grouped together for warmth as they waited for help to arrive. Dijkema himself was stuck standing on the tarmac without shoes. After emergency crews arrived, he was led off the cold ground into a firetruck, where he continued to film.

"I was left in the firetruck for a while by myself while they were trying to figure out what to do," he said.

While emergency crews arrived immediately, passengers were still forced to wait up to 50 minutes on the runway before being shuttled away.

Halifax International Airport Authority spokesperson Peter Spurway said the process for such an operation was more complicated than it appeared.

"The airfield is a secure area, people driving vehicles there need proper certification, proper licensing to do that," Spurway said. "And it’s (12:45 a.m.) on a Sunday morning, so there are circumstances that combine to prevent a quicker response to that."

Spurway called the emergency crew response "textbook," but said the airport’s process for picking up passengers in emergency situations could be improved.

"We will work hard to develop protocols to shorten that time should such a situation, such an extraordinary circumstance, present itself again," Spurway told CTV News. "I’m confident that we can do better than that."
