This question explores the intersection between Automobile Insurance (OAP 1) and Personal Liability (Section II of a Homeowners Policy). In Ontario, the liability coverage for a trailer is determined by its status: whether it is "attached" or "detached."
Under the OAP 1, liability coverage extends to a trailer while it is being towed by a power unit (the automobile) described in the policy. However, once the trailer is detached and parked, it is no longer considered a "motor vehicle" in operation. If a detached, parked trailer causes injury or property damage to a third party (for example, if it rolls down a driveway or someone trips over the hitch while it is on the insured's property), the Automobile Policy will not respond because the loss did not arise from the "ownership, use, or operation" of an automobile.
Instead, the Personal Liability section of a Homeowners, Condominium, or Tenant policy is designed to cover the insured’s legal liability for such incidents. Standard habitational forms typically include coverage for trailers that are not being towed or carried on an automobile. The RIBO Level 1 Blueprint requires brokers to understand this transition of risk. During Consulting and Advising, a broker must ensure the client knows that while their auto policy covers the trailer on the road, their property policy provides the necessary "premises liability" once it is unhooked. This technical distinction is vital for accurate Risk Identification and Assessment, ensuring that the client is never left in a "coverage gap" between their home and auto insurance contracts.
