Looking for father-in-law’s 1967 Valiant

Looking to find my father in laws 1967 Valiant he built and restored. His wife and 4 daughters would love the opportunity to talk to the current owner and see if there is a chance to buy the car back and fill the smallest piece of memories back since his passing. Was last in Alberta from what we can find. If anyone knows the owner, location, or any helpful piece of information that might bring my family some comfort I would be greatly appreciated if you passed this postings on to them. We just hope for a chance to talk.
