No article — and no calculator — can tell you what your case is worth. Anyone quoting you a number without your medical records is guessing. What this page can do is explain the factors Ontario lawyers and insurers actually weigh, so you walk into a free consultation informed instead of hopeful.
1. Injury severity and recovery
This is the biggest driver. A soft-tissue injury that fully resolves in weeks is valued very differently from a fracture, a herniated disc, a brain injury, or anything permanent. Insurers and courts look at medical evidence — diagnosis, treatment records, specialist opinions — not at how bad it felt. If you haven't seen a doctor, get seen. Undocumented injuries are nearly invisible to a claim.
2. Liability — how clear is fault?
Ontario applies contributory negligence: your award is reduced by your share of fault. A rear-end collision at a red light with a police report is about as clean as liability gets. A disputed intersection collision with no witnesses is not. Clear liability doesn't just raise value — it makes a lawyer far more willing to take the case.
3. Income loss and out-of-pocket costs
Missed work, lost business income, and reduced earning capacity are concrete, provable damages. Keep pay stubs, employer letters, and tax records. Medical and rehab costs not covered by OHIP or your benefits, prescriptions, mileage to appointments, and housekeeping help all count too. Receipts are evidence — keep everything.
4. Ontario's statutory deductible on pain and suffering
This is the Ontario-specific factor most people don't know about. Motor vehicle pain-and-suffering awards are subject to a statutory deductible unless the award exceeds a monetary threshold (and the injury meets the legal test of a permanent serious impairment). Both figures are indexed and change over time — ask a lawyer for the current numbers. Practical effect: smaller claims can be largely or entirely absorbed by the deductible, which is why lawyers screen minor-injury cases carefully.
5. Future needs
Serious injuries create future costs: ongoing physiotherapy, attendant care, home modifications, future income loss. These are often the largest component of big settlements, and they require expert evidence (medical, vocational, economic). A case with significant future needs is valued on projections, not just bills already paid.
6. Timing and conduct
Gaps in treatment ("you stopped physio for three months") get used against you. Giving a recorded statement to an insurer without advice can hurt you. And Ontario's 2-year limitation period means waiting too long can erase the claim entirely. See our guide to Ontario personal injury deadlines.

Take the free quizThe honest bottom line
Case value = (provable damages) × (clarity of liability) − (your share of fault) − (deductibles and thresholds), all filtered through real medical evidence. The range is enormous, and the only person who can value your case is a lawyer who's seen your file. The good news: the initial review is usually free.
