An Unforeseen Calamity
In a society governed by the rule of law, justice is generally defined as the wrongdoer being punished (under criminal law) or compensating the victim (through civil litigation). In certain circumstances, however, a wrongdoer bears no legal responsibility for their own negligence — and, remarkably, in this case the "wrongdoer" is the government itself!
In Hilderley v. His Majesty the King, 2026 ONSC 3212, the plaintiff couple owned a residential property in the Goulais River area of Ontario. They claimed that, for many years, their land had relied on a private drainage ditch to channel rainwater and snowmelt into Goulais Bay, without ever experiencing serious flooding problems.
However, in 2015, the defendants — Ontario's Ministry of Transportation and the Goulais Mission Local Roads Board — carried out road maintenance work, replacing a 12-inch culvert located beneath the street below their residence with a 24-inch culvert.
The plaintiffs alleged that the replacement culvert significantly increased drainage flow, causing large volumes of rainwater and snowmelt to surge into the drainage ditch on their land. Since 2015, every heavy rainstorm or snowmelt season brought severe pooling and flooding to the north side of their land. The flooding not only washed away soil but also eroded the foundation of their workshop, leaving trees and their large propane storage tank without stable support.
By 2023, the plaintiffs believed that approximately 30% of their land had become unusable due to erosion, and decided to commence litigation, seeking $150,000 in general damages and $50,000 in punitive damages from the two defendants, as well as an order requiring the removal or closure of the culvert in question.
The plaintiffs' claim was primarily grounded in negligence. They alleged that the defendants had failed to adequately consider the surrounding drainage system when designing, installing, and replacing the culvert, thereby altering the land's natural water flow patterns and ultimately causing flooding and land erosion.
In addition, the plaintiffs alleged that the defendants had breached provisions of the Drainage Act, by failing to ensure that the drainage system could properly channel water to an appropriate outlet.
The two defendants, in turn, sought to have the claim dismissed outright, raising three main grounds:
Section 18 of the Local Roads Board Act ("LRBA") grants local roads boards and the government statutory immunity, meaning the plaintiffs had no viable cause of action at all.
Section 50 of the Public Lands Act similarly provides comparable immunity protection.
Even if no statutory immunity applied, the claim may already have fallen outside the two-year limitation period under the Limitations Act, 2002.
The court found the key issues in this case to be:
Does the culvert form part of the "road"?
Does replacing the culvert constitute "road maintenance"?
The plaintiffs argued that the culvert was not the road itself, and that the defendants' work amounted to active construction, rather than mere maintenance, and should therefore not be protected by statutory immunity.
The court disagreed.
1. Does the culvert form part of the "road"?
Although the LRBA does not explicitly define "road," the court found that a road should not be limited to the asphalt or road surface itself, but should also include the ancillary infrastructure necessary to maintain the road's proper function.
The purpose of a culvert is to channel rainwater and surface water beneath the road, preventing pooling, washout, or erosion of the roadbed. As such, a culvert is, in essence, an inseparable part of the road's structure.
The court also cited past case law establishing that a road's drainage system is inextricably linked to the road itself — without culverts, many roads could not be safely used.
The court therefore held that the term "road" should be interpreted to include the culvert infrastructure situated beneath it.
2. Does replacing the culvert constitute road maintenance?
The court held that "maintenance" includes not only routine upkeep, but also necessary repair and replacement work.
The evidence showed that the original culvert had become damaged and had collapsed, rendering it unable to drain properly, which caused road flooding during spring snowmelt and heavy rainstorms.
The Local Roads Board had accordingly requested that the Ministry of Transportation carry out the replacement work, in order to ensure the road's safety and proper functioning. The court found that repairing a failed culvert was, in essence, part of road maintenance, rather than an independent new construction project.
Even accepting the plaintiffs' allegations that the new culvert was oversized, poorly designed, or improperly installed, the core of their claim still concerned conduct undertaken in the course of road maintenance, and therefore still fell within the scope of the statutory immunity provisions.
As a result, the court granted the defendants' motion, dismissing the plaintiffs' claim outright, without leave to amend and refile.
This case illustrates that Canadian courts, when dealing with public road maintenance work, tend to strictly apply statutory immunity provisions, in order to allow local roads boards and government departments to carry out their public infrastructure maintenance duties without facing broad exposure to civil claims.
Unfortunately, for citizens who suffer losses due to the negligence of government officials, it seems that the justice system may offer them no path to compensation at all, leaving them as sacrifices to the public interest.
In this case, if the culvert continues to cause flooding, erosion, or safety risks, the plaintiffs could apply pressure through political and administrative channels — including ongoing complaints to the Local Roads Board, their provincial MPP, relevant department heads, or even the Ombudsman — to push the government to reassess the engineering design. While these avenues may not necessarily result in monetary compensation, they could potentially bring about a correction of the problem.
