Aitchison graduated from Celtic's school of excellence at St Ninian's Academy in Kirkintilloch in February 2016, at which time he joined Celtic full-time and became part of their Under 17 squad. He played in the Celtic U17 side that defeated their Rangers counterparts 4–0 in the Glasgow Cup final in April 2016. At this time, he also signed a three-year contract. During his youth career he also appeared and scored in the 2015–16 and 2016–17 editions of the UEFA Youth League, found the net against senior clubs in the 2016–17 Scottish Challenge Cup, and won the Scottish Youth Cup in 2017.
Aitchison made his first team debut on 15 May 2016, becoming the youngest player ever to represent the club in a competitive match at 16 years and 71 days. He scored with his first touch in the match, providing Celtic's seventh goal in a 7–0 win over Motherwell, in turn making him the youngest ever player to score a competitive goal for the club. His next appearance for the first team came in January 2017, coming on in the final minutes of a home league match against Hearts and winning a penalty which Scott Sinclair converted for Celtic's last goal in a 4–0 win.
