AGCO issues 10-year suspension to trainer Jeffrey Gillis for buying illegal performance-enhancing drugs from convicted US veterinarian
- On May 24, 2025, Standardbred trainer Jeffrey Gillis was handed a 10-year suspension and fined $40,000 by Ontario’s regulatory authority responsible for alcohol and gaming oversight.
- This disciplinary action arose from an AGCO investigation linked to an FBI probe charging 27 people with distributing illegal performance-enhancing drugs in horseracing.
- Records show Gillis purchased illegal synthetic erythropoietin from U.S. Veterinarian Seth Fishman, who was among those federally charged for manufacturing and distributing banned substances.
- Following the AGCO’s decision, the governing body overseeing trotting in the United States informed Gillis that he will face a matching suspension, placing him on their list of banned trainers for the same 10-year period.
- This case underscores the AGCO and USTA's commitment to enforcing anti-doping rules and protecting sport integrity, horse welfare, and public trust in horseracing.
