In Ontario, there are a number of official forms that must be filled out when an auto insurance claim is made. OCF stands for “Ontario Claims Form”. The OCF-19 would be completed if you wanted to apply to an insurance company to have your injuries deemed “catastrophic”. If you are successful in getting the catastrophic designation, you will have access to much higher limits in terms of medical and rehabilitation benefits. Benefits for a non-catastrophic injury are typically capped at $65,000, whereas a catastrophic designation gives you access to up to $1 million in benefits.
