MacGillivray Injury and Insurance Law says a statement of claim has been filed with the Nova Scotia Supreme Court, suing Air Canada, Nav Canada, Halifax International Airport Authority and an unnamed captain and first officer for the crash on March 29.
The statement of claim says lead plaintiff S. Philip Cameron and class members are seeking $12 million in damages for physical and psychological injuries including anxiety, depression, post-traumatic stress disorder and insomnia.
The documents make a number of claims including that the airport kept the runway open when it knew or should have known that was not reasonably safe and that Nav Canada instructed the flight crew to land when it knew or should have known that conditions were unsafe.
The law firm says it is also filing a mass lawsuit that names 20 individual clients, in case the class-action lawsuit is not certified.
Air Canada, the Halifax International Airport Authority and Nav Canada all said they could not comment Tuesday as the matter is before the courts.
