If pedigree determines champions, then Trey is destined to be one. 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. At just 16 years old, Trey made his first unofficial ride behind Curtis Morin during the demonstration run the 2018 Calgary Stampede. He rode again at the fun run in Meadow Lake, Saskatchewan behind Chance Flad and Ross Knight, and made his first official ride at the 2018 Strathmore Stampede behind Jordie Fike. Before season's end, Trey picked up additional rides behind his father Layne MacGillivray and Mitch Sutherland. 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. Trey is a grade 11 student at Gus Wetter School in Castor, Alberta, and enjoys basketball, horses, hockey and hunting in the off season. Trey is single and makes his home in Halkirk, Alberta.
