The law firm of Morin and Miller filed the lawsuit in the Ontario Superior Court of Justice and is seeking class-action status.
The case involves Ford’s top-selling F-Series trucks, including the Louisville-made F-250. The suit also claims that latches on the Ford Expedition and Lincoln Navigator SUVs were defective.
According to the release, it would cost about $994 per four-door vehicle to replace the door latches. The firm also is asking for about $403 million in punitive damages.
The release said the Canadian firm is working with a law firm in Mount Pleasant, S.C., that also is planning to file a lawsuit against Ford related to more than 4 million vehicles sold in the United States.
The firms claim deaths and serious injuries resulted from defective latches that allowed doors to open during side-impact crashes.
Officials with Ford could not immediately be reached for comment.
Ford spokeswoman Kathleen Vokes told Reuters that the door handles and latch assemblies fully comply with all government and industry standards.
