Kosi Thompson Bio
Kosi Trevor David Thompson (born January 27, 2003) is a Canadian soccer player who plays as a midfielder or right back in Major League Soccer. He came through the Vaughan Azzurri youth system before joining the Toronto FC Academy in 2015, and he made his professional debut with Toronto FC II in May 2021. Thompson later established himself on the Toronto FC first team before a loan to Norway’s Lillestrøm and a 2026 trade to the Colorado Rapids. He has represented Canada at the youth international level.
Early Life and Background
Kosi Trevor David Thompson was born on January 27, 2003, in Toronto, Ontario, Canada. He grew up in the Greater Toronto Area, where he first took up organized soccer as a child. His early development came through local youth channels rather than a single national pathway, reflecting the layered club structure common in Canadian youth soccer.
Thompson began playing in the Vaughan Azzurri youth system, a respected development program in the region. In February 2015, at age 12, he joined the Toronto FC Academy, stepping into one of the country’s most established professional club academies. The move gave him daily access to professional-level coaching and a clearer route toward a senior contract.
At the Toronto FC Academy, he was coached by Terry Dunfield at the U14 level. Dunfield was quickly impressed by Thompson’s work on both sides of the ball and selected him as team captain, an early sign of the leadership qualities he would carry into his professional career.
Path to Soccer
Thompson progressed steadily through the Toronto FC Academy age groups. As a member of the academy, he helped the team win the 2019 U-16 Dallas Cup, one of the most prestigious youth tournaments in North America. He was also named to the 2019-20 Generation adidas Best XI, a recognition reserved for the top young players in the U.S. Soccer Development Academy.
Instead of transferring to a school with a formal agreement with the Toronto FC Academy, Thompson chose to remain at his existing school, Ursula Franklin Academy. In 2020, he signed a national letter of intent to attend Oregon State University and play for the Beavers men’s soccer team starting in 2021, but he later decided to turn professional rather than enroll.
Kosi Thompson Career
Early Career (2021)
On May 13, 2021, Thompson signed his first professional contract with Toronto FC II of USL League One. He made his debut for the second team on May 22, 2021, against North Texas SC, stepping into a competitive senior environment at age 18. Less than two weeks later, on June 2, he scored his first professional goal against Union Omaha, signaling an immediate impact at the lower-division level.
His first-team opportunity arrived after a strong showing during Toronto FC’s 2022 preseason. He signed a first-team contract and made his Major League Soccer debut on March 12, 2022, as a late substitute against the Columbus Crew. He started his first MLS match on April 2 against New York City FC and scored his first MLS goal on April 9 against Real Salt Lake.

Thompson’s 2022 season marked his real arrival in MLS. After breaking into the first team during preseason, he became a regular contributor across the midfield and attacking lines. His willingness to take on different roles, including midfield, right back, and centre-back, became a hallmark of his early professional career.
Later in 2022, he received international recognition when he was named to the 60-man provisional Canadian U-20 squad for the 2022 CONCACAF U-20 Championship. In 2023, he was loaned back to the second team for some matches, a period that coincided with his gradual transition into a defensive role.
Lillestrøm Loan (2023)
In August 2023, Thompson was loaned to Lillestrøm of the Norwegian Eliteserien for the remainder of the season, with the arrangement including an option for a permanent transfer. The move gave him exposure to European football and a higher tempo of play than domestic reserves soccer.
He made his Lillestrøm debut on September 3, 2023, against Aalesund, adapting quickly to the demands of a top-flight European league. Following the season, the Norwegian club declined the purchase option, and Thompson returned to Toronto FC.
Colorado Rapids Era (2026–Present)
