It would be tempting to describe three recent insurance decisions as a story about insurers becoming more aggressive or courts taking a harder line on claims. That wouldn't be supported by the cases. What they do show is something more practical. The evidence an insurer or policyholder preserves before a dispute can determine whether an argument is available when the disagreement finally reaches a court.
In Prestidge v. Definity Insurance Company, 2026 NBCA 49, the insured challenged the rate paid for driving to medical appointments after an automobile accident. Definity had reimbursed $0.30 per kilometre. The insured sought $0.57, referring to government mileage rates and an earlier court decision. The New Brunswick Court of Appeal concluded that the lower rate was reasonable on the evidence before the application judge, but carefully declined to establish a universal reimbursement rate. The insured had not provided evidence of her actual travel costs, and the government benchmarks didn't automatically determine the insurer's obligation.
The distinction is important for both sides of a benefits claim. Insurers may select rates and apply operational guidelines, but their initial choice isn't necessarily binding on an insured who challenges whether the amount is reasonable. Equally, an insured who seeks a higher amount should understand why evidence of actual cost may be more useful than a number taken from an unrelated public program. The Court of Appeal also declined to determine whether the policy had to cover transportation at all. Definity had conceded that point, so the dispute was about quantum. That limited holding is considerably more informative than a headline announcing that a particular mileage rate had been approved for everyone.
A different record problem appeared in West York Sales and Leasing Inc. v. Dominion of Canada General Insurance Company, 2026 ONCA 553. The dispute arose under an Ontario fleet automobile policy using the OPCF 21A monthly reporting endorsement. A car leased before the policy commenced was omitted from the initial schedule, then added in the month after a collision. The Ontario Court of Appeal rejected an interpretation that made coverage retroactive to the start of the term for that vehicle. The reporting requirement had a real role in determining when coverage began, and a monthly premium arrangement did not necessarily mean every vehicle connected to the business was insured before it was reported.
For businesses managing changing inventories of automobiles, the lesson isn't that every late report defeats every claim. The relevant wording, vehicle history and exact reporting dates matter. It's that the business's fleet register and the insurer's schedule can't be treated as administrative details disconnected from insurance protection. A broker who reconciles those records when a policy begins may prevent a much more expensive disagreement than one who assumes the next monthly spreadsheet will sort everything out.
The third dispute, Trecartin v. Sonnet Insurance Company, 2026 NBKB 96, involved a house destroyed by fire. As described in independently corroborated legal reporting, Sonnet succeeded on a vacancy exclusion even though the residence remained furnished and its owner had been visiting it. The policy definition considered the departure of residents, not only the presence of furniture. The insurer advanced other grounds involving alleged misrepresentation in an online application and a material change in risk from using generator power. Those separate arguments weren't proved on the evidence described in the published accounts, including because the insurer couldn't reproduce the relevant original online application questions and responses.
That last detail matters as insurers digitize distribution. An application submitted years earlier can look like an old transaction record until an insurer needs to prove what the applicant was asked. A current online form or a field in an internal database may not establish what appeared on a customer's screen at the relevant time. Preserving forms, versions, answers and dated communications can therefore be an insurance control rather than simply an IT retention choice.
These aren't identical legal problems. One concerns the reasonableness of reimbursed expenses, another the effective date of fleet coverage, and the third a property vacancy exclusion together with separate underwriting allegations. The facts and the policy wordings differ, and only the Prestidge judgment was independently reviewed here against full official court reasons. The West York and Trecartin accounts are based on detailed, independently corroborated secondary reports, with full primary reasons still needing confirmation. They shouldn't be collapsed into a supposed national shift in insurance law.
There is nevertheless a common operational question that any insurer, broker or commercial policyholder can ask: can the organization produce the record that supports the decision it's making? For a reimbursement, that may mean the cost and reasonableness evidence. For a fleet, it may mean the schedule and date the insurer received notice. For a property policy, it may mean the actual terms, application records and reliable facts about occupancy. The record won't always decide the claim, but without it an otherwise plausible position may become difficult to prove.
This is also why better case reporting should explain what the court actually decided and what it left open. A victory on one exclusion isn't a victory on every defence. Upholding one mileage rate isn't setting it for every claim. Denying coverage for one omitted vehicle isn't declaring every unreported vehicle uninsured. The useful professional guidance lies in the limits of the decision as much as in its result.
For Canadian businesses, insurance is an asset only when its protections can be understood and used. That requires communication among procurement, brokers, operations, claims and legal teams long before a dispute starts. The person keeping the vehicle schedule or the original policy application may feel far removed from a future coverage question. In these cases, those ordinary records were close to the centre of the litigation.
