Public Auto Insurance

Study guide: Exam 6C

Public Auto Insurance is the delivery of compulsory automobile coverage by a government-owned monopoly rather than by competing private insurers. Four Canadian provinces use it in some form: British Columbia (ICBC), Saskatchewan (SGI), Manitoba (MPI) — all monopolies for basic coverage — and Quebec (SAAQ), which is public for bodily injury only, with property damage left to private insurers.

• Arguments made for the public model: lower expense ratio (no commissions, no advertising, no profit margin, a single administrator); universal availability with no residual market problem; premiums collected efficiently with vehicle registration; and the ability to fund road safety programs from the same body.
• Arguments made against: no competition and therefore no innovation or service pressure; the political dynamic that suppresses rates before elections and requires large catch-up increases afterward; cross-subsidies that are decided politically rather than actuarially; and, where the monopoly extends to optional coverage, no consumer choice at all.
• Rate setting is public. The insurer files with a provincial utilities board and the hearing is adversarial and on the record — which makes the actuarial work unusually transparent, and unusually contested.
• Capital and solvency. A public insurer is not subject to OSFI and often not to the MCT, so its capital adequacy is governed by a legislated rate stabilisation or capital target instead. Where governments have drawn surpluses into general revenue, the resulting capital deficiency has been a recurring controversy — ICBC's is the best-documented Canadian case.
• Comparisons are hard and often abused. Cross-province premium comparisons are meaningless unless the product is held constant: benefit levels, access to tort, accident benefit limits, whether bodily injury is even in the private premium, and vehicle and driving-density differences all vary. See the Quebec example for the clearest illustration.
• Evaluation should follow the Social Insurance framework: objective, sustainability, efficiency, equity, and effect on the private market — including the fact that a basic-coverage monopoly still leaves a private market for optional and excess coverage in BC, Saskatchewan and Manitoba.

Is the Public Insurer Cheaper? Province X (public monopoly) reports an average auto premium of \$1{,}150 and an expense ratio of 18\%. Province Y (private, competitive) reports \$1{,}680 and an expense ratio of 28\%. Both have similar populations and vehicle counts.

Can one conclude the public model is cheaper?

Answer Not from these figures. The expense difference is real but explains only part of the gap, and the product may not be the same.

Decompose the premium. At a 70\% target loss ratio, expenses of 28\% versus 18\% account for roughly 10 points of premium — about \$150 on Y's premium. The remaining gap of roughly \$380 must come from loss cost, not from efficiency.

Then ask why loss costs differ:

• Benefit design. Does X restrict tort access, or cap accident benefits more tightly? A cheaper product is cheaper for that reason, not because of the ownership model.
• Exposure. Traffic density, urbanisation, theft rates, weather, repair costs and litigation propensity all differ by province and none is under the insurer's control.
• Capital adequacy. Is X's premium actually covering its costs? A public insurer running down a rate stabilisation reserve reports a low premium and accumulates a deficit — the ICBC pattern. The honest comparison uses premium adequate to fund the benefits, not premium charged.
• Off-premium funding. If X funds part of its scheme from vehicle registration levies or general revenue, the premium understates the cost to the citizen.

The defensible statement is narrow: the public model demonstrably delivers a lower expense ratio, and that advantage is genuine. Everything else in the comparison is product design and exposure, and attributing it to ownership is the error the question is testing.
