From the Motor Accident Insurance Commission website:
Is CTP insurance good value?
Yes. Unlike many other types of insurance, CTP provides unlimited indemnity to the insured. Benefits paid to the injured party depend on the extent of the injuries and can include the cost of ambulance, hospital and medical treatment, rehabilitation, loss of income and long-term care. Limits may apply with respect to loss of income (the upper limit being three times average weekly earnings per week) and limits may apply in certain circumstances regarding the payment of legal costs.
