Long Term Disability cases are at their essence, contract cases.
In a long term disability case, there is a contract of insurance between the Plaintiff and the Defendant. The contract is between the Defendant insurance company (Great West Life, Canada Life, Manulife, Sun Life, Empire Life, Desjardins Insurance, SSQ Insurance, Co-Operators Insurance, RBC Insurance, La Capitale Insurance etc.) and the Plaintiff policy holder.
A car accident case for pain and suffering or a dog bite case is very different because there is no contract between the Plaintiff accident victim and the at fault party. These are straight tort cases. Accident benefit cases for first party insurance are certainly different, but the legal principal is the same given that the cause of action for tort cases is not contractural. In both car accident and dog bite cases the cause of action is in negligence against the at fault party.
The policy holder can be a company which covers all of its employees (a group policy through your employer), or it can be an individual policy of insurance.
In the case of an individual policy of insurance, the policy holder goes out and purchases the insurance on their own either directly through the insurance company, or through an insurance broker. The insurance broker may sell a variety of different policies underwritten by a variety of different companies. Variety is the spice of life, so getting options to purchase your insurance is a good thing. That way the consumer can compare and contrast prices, definitions, exclusions and benefits between polices. Having a good and knowledgable insurance broker is very helpful when comparing and contrasting long term disability policies.
