In Ontario, the definition of the conditions under which injured parties are permitted to sue another motorist to recover for their injuries is known as

• A. The absolute liability provision
• B. The threshold
• C. No-fault insurance
• D. The tort doctrine

Answer: (B)

The main idea being tested is the threshold—the gate that decides when a person injured in a Ontario auto accident may sue another motorist for pain and suffering. In Ontario, auto insurance operates on a no-fault basis for most benefits, but a civil claim for non-pecuniary damages is allowed only if the injury meets the threshold. That threshold requires a serious impairment of an important physical, mental, or psychological function (often described as a serious or permanent impairment). If the injury doesn’t meet that standard, the no-fault benefits apply and a tort action for pain and suffering isn’t available. The other terms don’t fit because they relate to broader or different concepts: absolute liability isn’t the Ontario rule here, no-fault insurance describes the overall system, and the tort doctrine is a general idea rather than this specific gatekeeping rule.
