The rear corner looks empty, the shed fits and the neighbour says the fence has always been there. Before marking the footing locations, check whether someone else has a registered right to use part of that space.
An easement may affect access or services across land you own. Its actual terms and location matter. A deck that satisfies a setback can still conflict with registered rights, and a fence line is not reliable proof of either a property boundary or an easement boundary.
Collect the documents before the layout stakes
Find the property documents from your purchase and any existing survey or reference plan. Ask your real-estate lawyer or another appropriate professional what current title information and registered instruments are needed to assess the proposed work. Do not assume an old plan reflects every later registration.
Title and rights
Obtain and interpret relevant registered documents.
Location
Use appropriate survey information to place the affected area.
Planning and permits
Check the actual deck or shed proposal with the municipality.
Excavation safety
Arrange required locates, including private-service needs.
Decision guide; not a construction detail or a substitute for the project specifications.
Ontario: land registry overview explains how Ontario land records can be accessed through OnLand and warns that these records can be complex. It identifies lawyers, title searchers and surveyors as sources of professional help. Obtaining a document and interpreting its effect on your construction are separate tasks.
Ask for the actual instrument and referenced plan where relevant, not just a note saying "subject to easement." The short notation may not explain who benefits, what activities are permitted or what restrictions affect the proposed structure.
Put the proposed structure on the same plan
Have the deck or shed layout shown against reliable property information and the identified affected area. Include stairs, overhangs, foundations and access around the structure, not just the main rectangle. A stair landing can be the part that conflicts even when the deck platform does not.
Ask the lawyer to interpret the rights and restrictions, and a surveyor to resolve location or boundary questions where needed. These are different professional questions. A contractor can build to an agreed layout; that does not make the contractor the authority on ambiguous title rights.
For a shed, also show how it will be delivered and how it could be moved for maintenance. A building described as "portable" may still obstruct access. Wheels or skids do not automatically settle the meaning of an easement.
Keep four checks separate
First establish the boundary and registered rights. Then check zoning and any required permits for the proposed structure. Our deck setback guide and Ontario shed permit guide cover those separate approval questions.
Before excavation, arrange the required utility locating process and identify whether private services need additional locating. Ontario One Call before digging explains that stage. A utility mark is information about underground infrastructure; it does not grant permission to build over an easement or establish your boundary.
Likewise, municipal approval should not be treated as a private agreement releasing registered rights. If a proposed layout conflicts, obtain professional advice about redesign or whatever formal permission or legal process is appropriate. A friendly verbal conversation with someone nearby is not a dependable substitute.
Test a less complicated layout first
Before pursuing a legal change, see whether moving or reshaping the structure preserves its useful purpose. Rotate the shed door, relocate stairs or reduce a platform where that achieves the same day-to-day use. Show the revised version to the people advising you so the decision relates to an actual plan.
Do not price only the main structure. Include any access corridor, maintenance clearance and changes to grading or drainage. A redesign that avoids one restriction should not create a new runoff or access problem beside it.
Keep the reviewed layout, relevant title documents, advice and approvals in the project folder. Give the installer a clear site plan and identify what must remain unobstructed. If excavation reveals a service or condition inconsistent with the plan, stop the affected work and have it resolved.
The aim is to put the structure somewhere you can confidently keep and maintain it. A little document work before the holes are dug is far easier to manage than moving a finished deck because the apparently empty strip had another job all along.
