If you are competing at Equine Canada sanctioned competitions, please be advised of rule changes prohibiting the practice of using injectable magnesium, gamma amino butyric acid (GABA) or hydroxy-gamma butyric acid (hydroxyl-GABA).
These rule revisions, which have been adopted and are effective immediately, empower EC licensed officials to take action if they personally witness the injection or attempted injection of a horse. A refusal by a person to comply with a request from an EC licensed official to provide the injection equipment in and of itself constitutes a violation that would result in a violation consistent with the sanction for a Class 2 substance on the EC Drug Classification Scheme.
