Two horse trainers appealed suspensions and fines imposed after their horses tested positive for trace amounts of methamphetamine.
The Ontario Racing Commission heard expert evidence that the extremely low levels of the drug were the result of environmental contamination, not administration, and would not enhance performance.
The Commission waived the absolute liability rule for positive tests, finding that penalizing the trainers for unavoidable environmental contamination would be unjust and contrary to the public interest.
The appeals were allowed and the penalties set aside.
