Jonas Haineault was 68 when he left Hythe, Alberta, on a bus bound for Edmonton on August 15, 1977, and was never heard from again. He had been visiting family in Lymburn and his known journey began there and took him to nearby Hythe before he boarded the bus.

Haineault is recorded as an Indigenous male, born in 1909, about 5 feet 8 inches tall, weighing roughly 141 pounds with a slender build, brown eyes, black hair and wearing false teeth. No clothing description is listed, and the record contains no confirmed sighting after he boarded the bus or any evidence that he reached Edmonton or changed plans.

The last confirmed movement is him boarding the Hythe‑to‑Edmonton bus on August 15, 1977; what happened after that remains unanswered. If anyone knew Jonas, saw him during that trip, or has information about his intended plans or encounters en route, please contact the Wood Buffalo RCMP, Crime Stoppers, or the National Centre for Missing Persons and Unidentified Remains.
