How a cadastral operation unfolds
A single point of contact, from site analysis to official registration.
Analysis and feasibility
Cadastre, titles, easements and municipal bylaws are verified to confirm the project is feasible as envisioned.
Field survey and research
Existing markers and monuments are located and surveyed, then the new limits are computed.
Cadastral plan and approvals
The plan is prepared to the municipality's and land registry's requirements, then submitted for approval.
Marking and registration
The new limits are marked on the ground and the new lot numbers are registered in the land register.
Subdivision: straight answers
What is a cadastral operation?
It's any change made to Québec's cadastre by a land surveyor: splitting one lot into several, merging lots into one, correcting or replacing a lot number. Each operation produces new lot numbers registered in the land register.
What's the difference between a subdivision and a simple lot split?
A subdivision is a complete development project: creating multiple lots, streets and public spaces, with a master plan and municipal approvals. A lot split is a simpler operation, often one lot divided into two, that must still comply with the municipality's subdivision bylaw.
What approvals are required?
The municipality must authorize the operation: subdivision and zoning bylaws and, depending on the case, easement or private-road agreements. The plan is then filed with the land registry office and registered. We prepare the plan and coordinate the steps with you.
How long does a cadastral operation take?
It depends on the project's complexity and the municipality's approval timelines, which vary from one city to another. Once the mandate is confirmed, we present a realistic schedule for your file.
Can two lots be merged to build?
Yes, it's a common operation: cadastral merger fuses two lots into one, often required by the municipality before issuing a permit for a building that straddles a lot line. We prepare the plan and follow through with the land register.
