McCreadie pulled his brother's old car out of the weeds, put an engine in it and made his racing debut in the sportsman class in the 2010 season opener at Can-Am Speedway in LaFargeville, New York.[2] When his motor broke in the season's last race, family friend Pierre Daigenais pushed McCreadie into the 358-Modified class the next year.[3]
After several years of driving with Daigenais’ support and then taking care of the racing responsibilities on his own, McCreadie joined with car owners Pat and Tammy Flack to drive their #28 in both the big block and small block divisions.[3]
In addition to Can-Am, McCreadie has competed successfully in New York at Fulton Speedway, Evans Mills Speedway, Mohawk International Raceway in Hogansburg, and Thunder Mountain Speedway in Lisle; and in Ontario at Brockville Speedway.[1][4][5] He captured the 2023 and 2025 track crowns at Glen Ridge Motorsports Park in Fultonville, New York.[6]
