Time Attack is one of the most affordable forms of motorsports, allowing drivers to compete in any car in good mechanical condition.
For those who want to use a ‘stock car’ only a Class ‘TA’ license and a helmet is required. But for those who want to go faster the 2023 Ontario Time Attack rulebook has been released, available on their website. Racers are strongly advised to plan their build early to avoid last minute disappointment!
