The claimant owned a truck stop on Highway 17.
The Province constructed a new section of Highway 417 for public safety reasons, which rerouted traffic and altered access to the claimant's property.
The claimant sought compensation for injurious affection under the Expropriations Act.
The Ontario Municipal Board awarded damages, finding the interference constituted an actionable nuisance and resulted from the construction, not the use, of the highway.
The Divisional Court upheld this decision.
On further appeal, the Court of Appeal held that while the interference was substantial, the Board erred in its reasonableness analysis by failing to properly balance the competing interests, particularly the significant public utility of the new highway.
The Court of Appeal concluded the interference was not unreasonable, allowed the appeal, and dismissed the claimant's claim for injurious affection.
