The appellant appealed the Minister of Transportation's decision to downgrade his commercial AB driver's licence to a G class licence due to his cardiovascular disease and the implantation of an implantable cardioverter/defibrillator (ICD).

The Licence Appeal Tribunal found that the appellant's medical condition, specifically the ICD and documented ventricular tachycardia, posed a risk of sudden incapacitation that exceeded the acceptable threshold for commercial drivers under the Canadian Council of Motor Transport Administrators Medical Standards.

The Tribunal confirmed the Minister's decision to downgrade the licence, concluding that the condition was likely to significantly interfere with the appellant's ability to drive a commercial motor vehicle safely.
