Gaëtan Ethier, 75, vanished after a routine ferry crossing in Ottawa in November 2013. The last confirmed sighting placed him on the Cumberland Ferry heading from Ottawa toward the Quebec shore; after that short trip there has been no contact, no confirmed sightings, and no public details about what happened next.

He is described as a white male, 5 feet 10 inches, slim, with short white hair. On the day he disappeared he wore beige casual pants, a blue checkered shirt, a grey vest, and black shoes. The Ottawa Police Service Missing Persons Unit handled the investigation, but few facts have been released and the case has gone cold.

The disappearance ends at the river crossing with no public explanation. Did anyone see Mr Ethier on that ferry or in the area that day, or have information about his movements before or after the crossing?
