Aubrey French, who lived in a farmhouse with his wife Blanche in Cookshire-Eaton, was involved in an accident with a Sûreté du Québec truck last Friday at around 5 p.m.
Police were responding to an emergency call in the small town of East Angus, and say French was turning left out of a parking lot when his car was struck.
French's grandson, Aaron Thomas, and Brenda French-Thomas, French's daughter, are hoping for more details.
"He'd never had an accident in his life and, you know, it wasn't the way he probably should have gone," French-Thomas said.
For now, they say there isn't anything they can do but wait for the police investigation into the accident to wrap up and for the coroner's report to be released.
Montreal police have taken over the investigation because the case involves the provincial police.
Const. Dany Richer said investigators are still trying to determined exactly what happened.
