Can I Build or Put a Dock on the Shore Road Allowance in Front of My Cottage in Ontario?

TSL Written by the Treadstone Law Team· Updated November 6, 2026

It depends on who owns the strip and what the municipality allows. A shore road allowance inside a municipality is a highway unless it has been closed, and a highway, including an unopened road allowance, is owned by the municipality that has jurisdiction over it. If the strip in front of your cottage is a shore road allowance inside a municipality, it is generally owned by the municipality rather than you, and whether it is one depends on your lot, so confirm with the municipality or a lawyer.

A municipality closes a road allowance by by-law, which must happen before it can be sold to an abutting owner, and the by-law takes effect only when a certified copy is registered in the land registry office. Separate municipal by-laws can also regulate fill, topsoil removal and changes to the grade of land, and can require permits.

Whether a particular allowance can be closed, sold or used by you depends on local policy, where the water's edge sits and other issues that vary from place to place. Other approvals may also apply to work at the water. Before you build a dock, shed or stairs, ask the municipality in writing what it permits and speak with a lawyer about your specific lot.

Key takeaways

  • A shore road allowance in a municipality is generally a highway, and an unopened one is owned by the municipality.
  • A road allowance must be closed by by-law, registered in the land registry office, before it can be sold to an abutting owner.
  • Fill, topsoil removal and grading may need a permit under a municipal site alteration by-law.
  • Ask the municipality in writing before building, because closing and selling an allowance depends on local policy.
