Who is responsible for maintaining a private road shared by multiple Ontario properties?

When several properties share access over a private road, the responsibility for maintenance is typically set out in the registered easement or right-of-way instrument on title. If the instrument specifies a cost-sharing formula — for example, equal shares among all users, or shares proportional to road frontage or usage — that formula is generally binding on all current and future property owners.

If the registered instrument is silent on maintenance or cost sharing, the law does not automatically impose a duty on any one party to maintain the road for the benefit of the others. Courts have sometimes implied a duty to contribute proportionately, but this is uncertain and depends on the specific instrument's wording and the circumstances.

In practice, disputes arise when one landowner performs maintenance unilaterally and then tries to recover contributions from the others, or when no one maintains the road and it deteriorates. If the road becomes impassable and access is blocked, those whose property access depends on the road have a stronger case for demanding maintenance or sharing costs.

The best solution is a registered road use and maintenance agreement among all affected property owners that defines each party's share of costs, a process for approving repairs, and a mechanism for collecting unpaid contributions. A lawyer can draft and register this agreement, and it will bind future purchasers of each property.
