Moral hazard in Canada: why insurers watch for incentive-driven behaviour that can worsen loss.
Moral hazard is the risk that a person’s behaviour, incentives, or honesty problems will increase the likelihood or size of a loss once insurance protection exists.
Underwriting is not only about the property, vehicle, or medical facts. It also considers whether the insured’s incentives or conduct could make the exposure less predictable or less trustworthy.
Canadian insurers look for signs that an applicant or insured may present an elevated behavioural risk. Depending on the line of business, that can involve misrepresentation, a weak loss-prevention approach, claims patterns, poor controls, or evidence that the insured may treat the covered property or activity less carefully because insurance is available.
This does not mean every claimant or high-risk insured is acting dishonestly. It means underwriting has to consider behaviour as part of risk selection.
If a commercial applicant has repeated avoidable losses, weak maintenance practices, and inconsistent information on the application, the underwriter may see a moral-hazard concern in addition to the physical risk itself.
Moral hazard is not just another name for fraud. Fraud is one possible issue, but the broader concept includes incentive and conduct problems that can increase expected loss.
It is also wrong to confuse moral hazard with adverse selection. Adverse selection is about who seeks coverage; moral hazard is about how behaviour changes or what conduct risk the insurer sees.
The meaning is consistent across lines, but the evidence used to assess it varies widely between personal lines, commercial insurance, life insurance, and benefits coverage.
