- 2022: Ponoka Stampede Champion Outrider, Calgary Stampede Aggregate/Safety Champion Outrider
2022 was a memorable year for Trey. He won the first major event of his career in 2022 at the Ponoka Stampede outriding for Ross Knight, followed it up by winning the Calgary Stampede Aggregate/Safety Championship and the Battle of the North behind his father Layne MacGillivray who ultimately won the World Chuckwagon Championship. For the second consecutive year Trey placed third in the World Standings.
Trey made his first official ride at the 2018 Strathmore Stampede behind Jordie Fike. Trey credits his father Layne, as well as outriders Chance Flad, Casey Knight and Ethan Motowylo with being the biggest help of his young career so far.
A 4th generation chuckwagon competitor, Trey is the son of current driver Layne MacGillivray, the grandson of former drivers Dennis MacGillivray and Wayne Dagg, and is the great-great-nephew of former driver and legendary chuckwagon promoter Cliff Claggett. Trey enjoys basketball, horses, hockey and hunting in the off season. Trey is single and makes his home in Halkirk, Alberta.
