Key takeaways
  • A road allowance that is a highway is owned by the municipality that has jurisdiction over it, subject to any reserved rights.
  • A municipality can dispose of an established or assumed highway only through a closing by-law after public notice.
  • Conveying submerged parts of a road allowance requires the Ministry of Natural Resources' consent.
  • Cottages or other structures on a shore road allowance can cause problems with transfers, mortgages, insurance claims and estates.

A buyer of lakefront property sometimes discovers, on the survey or in the title search, a strip of land between the lot and the water that the seller does not own. It is a shore road allowance, and it can affect privacy, access, docks and the value of the property.

This article explains in plain language who owns these strips in Ontario, whether you can buy one, and what it means for how you use the shoreline. The answers depend on each municipality and each strip, so a lawyer should confirm the details.

What a shore road allowance is

Many Ontario lakes and rivers were surveyed with a strip of land reserved along the water for a possible public road. In many places the road was never built, which is why people call it unopened. On the ground it may look like part of the cottage lot, with lawn, trees or a dock path.

Municipal road allowances laid out by Crown surveyors, and those shown on registered plans of subdivision, are highways under s. 26 of the Municipal Act, 2001.

Who owns it

A highway is owned by the municipality that has jurisdiction over it, subject to rights reserved by the dedicator or other landholders. Owning the cottage lot next to it does not make you the owner of the allowance.

The municipality administers and disposes of shore road allowances, and the province has no direct role in that. For that reason, your first call about an allowance is usually to the municipality, not a provincial ministry.

Can you buy it?

Sometimes. A municipality can get rid of an established or assumed highway only through a closing by-law under s. 34 of the Municipal Act, 2001, after giving public notice. Closures are often requested so the land can be conveyed to the abutting owners.

Whether a particular allowance can be bought depends on the municipality's own surplus-land policy, the public notice process, and, for submerged land, ministry consent. Nothing guarantees a sale.

StepWhat applies
Ask the municipalityIt administers and disposes of the allowance
Closing by-lawRequired under s. 34 of the Municipal Act, 2001, after public notice
Submerged portionsThe municipality must get the Ministry of Natural Resources' consent under s. 43 before conveying them
Blanket consentThe ministry says it can issue a blanket consent letter on request

Expect a purchase to involve a municipal process, possible costs and a lawyer to complete the transfer. Price and timing depend on the municipality, so ask it directly.

What it means for how you use the shoreline

If the municipality owns the strip, you may not have the right to build on it, exclude the public, or assume it is part of your lot. Structures on a shore road allowance can cause problems with land transfers, mortgages, insurance claims and estates.

Which rules apply depends on who owns the shore strip and the water bed. Ask your lawyer to confirm before you build, repair or buy.

What to do next

If you are buying, raise the allowance early, ideally before your offer becomes firm. If you already own, find out what the municipality knows about it and whether any structures sit on it.

Frequently asked questions

Do I own the land between my lot and the water?

Not necessarily. If a road allowance runs along the shore, the municipality that has jurisdiction over the highway generally owns it, subject to reserved rights. Your survey and title search will show whether it applies to your lot.

Can I buy the shore road allowance next to my cottage?

It may be possible, but the municipality must pass a closing by-law under s. 34 of the Municipal Act, 2001 after public notice. Submerged portions also need ministry consent before the municipality conveys them. Availability depends on the municipality's policy.

Is it a problem if my cottage sits partly on the allowance?

It can be. Cottages or other structures on shore road allowances can cause problems with transfers, mortgages, insurance claims and estates. A lawyer can explain the options for your situation.

Does the province decide whether I can buy it?

Not directly. The municipality administers and disposes of the allowance, and the province has no direct role. The one provincial step is the ministry consent for submerged portions.
