Early Life and Background
Kosi Trevor David Thompson was born on January 27, 2003, in Toronto, Ontario, Canada. Growing up in the Greater Toronto Area, he was introduced to organized soccer at a young age and joined the Vaughan Azzurri youth system, where he built the technical foundation that would later support his professional career.
In February 2015, at age 12, Thompson joined the Toronto FC Academy, a move that marked the beginning of his development within a professional club structure. Terry Dunfield, who became his coach at the U14 level, was quickly impressed with Thompson’s performance both on and off the field, selecting him as team captain. As part of the TFC Academy, he contributed to the team’s success at the 2019 U16 Dallas Cup and was named to the 2019-20 Generation Adidas Best XI.
Rather than transfer to a school affiliated with the Toronto FC Academy, Thompson chose to remain at his current school, attending Ursula Franklin Academy in Toronto. In 2020, he signed a national letter of intent to attend Oregon State University and play for the Beavers men’s soccer team beginning in the 2021 season. However, he ultimately decided not to enroll at Oregon State, choosing instead to begin his professional career.
Path to Professional Soccer
Thompson’s progression through the Toronto FC Academy served as the foundation for his transition to the professional ranks. His leadership as a young captain and his standout performances in prestigious youth competitions helped position him as a prospect capable of contributing at the senior level.
The decision to forgo a college pathway at Oregon State University allowed Thompson to accelerate his professional timeline. By remaining with the Toronto FC organization, he was able to integrate into the club’s reserve side while continuing his development within a familiar environment. His inclusion in the 2019-20 Generation Adidas Best XI highlighted his standing among the top young players in North America, reinforcing the club’s confidence in his long-term potential.
