A survey tells you where things actually are. The parcel register tells you what’s registered against the property. Both matter, and they answer different questions. A parcel register might say nothing’s wrong, while the survey shows the neighbour’s shed sitting two feet onto your client’s land. Lawyers and underwriters pull both at closing. The broker who can read a survey before submitting catches the problems early.
This article walks through what an Ontario land survey shows, how to read one, and what to do when something on the survey changes the deal.
What an Ontario land survey actually is
The most common survey you’ll encounter is a Surveyor’s Real Property Report, or SRPR. Older versions of the same document went by other names: Building Location Survey, Mortgage Survey, Title Survey, As-Built Survey. They all mean roughly the same thing. The Association of Ontario Land Surveyors standardized the modern name as SRPR.
An SRPR is a legal document prepared by a licensed Ontario Land Surveyor that illustrates the surveyor’s professional opinion of the property’s boundaries and the location of every visible structure on or near them. It is dated, signed, and tied to a specific moment in time. Think of it as a photograph of the property’s physical condition on the day it was surveyed.
Important: an SRPR is not filed with the Land Registry Office. It’s a private document that stays with the surveyor’s file and the original client. That’s a key difference from the parcel register, which is a public record.

The four types of Ontario surveys
Brokers should know the difference between the four basic survey types because they show up in different contexts.
- Surveyor’s Real Property Report (SRPR). Residential transactions. Shows boundaries, buildings, fences, easements, encroachments. What this article focuses on.
- Reference Plan (R-Plan). Registered at the Land Registry Office. Used to legally describe new parcels, severances, or easements. Identified by a number like “66R-14738” where 66 is the registry office, R indicates reference plan, and the number is the unique identifier. Reference plans replaced the old “metes and bounds” written descriptions in the 1960s.
- Plan of Subdivision (M-Plan or Registered Plan). Used by developers to create new lots in a subdivision. Once registered, the lots become part of the public record and can be sold individually.
- Condominium Plan. Creates three-dimensional condo units. Unit boundaries are the physical surfaces of the building.
For day-to-day broker work, the SRPR is the document you’ll be asked to look at. The other three are mostly relevant when something unusual is happening with the parcel (a severance, a new build, a condo conversion).
Where to get a survey
Three main paths.
- From the homeowner. Most often, the homeowner has a copy from when they purchased. Ask early in the file. If they have one, get a clear scan.
- Protect Your Boundaries (PYB) database. The largest searchable database of existing Ontario survey plans, particularly strong in the GTA. You can search by address and purchase historical surveys. Affiliated with the Association of Ontario Land Surveyors.
- The original surveyor. If you know which surveyor prepared the report (it’s on the document), you can request a copy directly. Most surveyors keep their files for decades.
- Commission a new one. When no existing survey can be found or the existing one is too old to rely on, the buyer hires a licensed Ontario Land Surveyor to prepare a new SRPR. Cost varies by lot size, complexity, and location. Typical residential range in Ontario is $1,500 to $3,500, with Toronto and other urban centres often at the higher end. Turnaround is usually one to three weeks.
What’s on an SRPR
A typical SRPR has a title block at the top or side and a drawing of the property in the main area. Here’s what you’re looking at.
- Title block. Contains the property address, legal description, name of the client who commissioned the survey, the surveyor’s name and licence number, the survey date, the scale of the drawing, and the name of the firm. Always check the date first.
- North arrow. Orientation. Important when comparing the survey to the property in person or to satellite imagery.
- Property boundaries. The lines defining the lot. Each boundary line has a bearing (the direction it runs, given in degrees, minutes, seconds) and a distance (in metres). Together these are called “bearings and distances” and they’re how surveyors describe the perimeter precisely.
- Buildings and structures. The house, garage, sheds, decks, pools, anything substantial. Each structure has measurements showing its location relative to the property lines. These are called “ties” or “setbacks.” A house tied “1.52m to the north property line” sits 1.52 metres from that line.
- Fences. Where they are, and whether they sit on the property line or off it. Fence-line discrepancies are one of the most common boundary issues.
- Easements. Shown approximately, usually with a dashed line or hatched area. The easement instrument number is referenced. The actual easement language lives in the registered instrument, which you’d pull from the parcel register.
- Encroachments. When a structure crosses a property line, the surveyor marks it. Could be the client’s structure on a neighbour’s land, or vice versa. Either way it’s a flag.
- Surveyor’s certificate. A signed and dated statement at the bottom or side of the plan certifying that the surveyor prepared the work in accordance with the Surveyors Act and AOLS regulations. Without this, the document is not a legitimate SRPR.
- Reference to underlying plans. The SRPR references the original subdivision plan, reference plans, or registry documents that define the legal boundaries. Lawyers and underwriters cross-check these references.
The four broker concerns
When reading a survey for a deal, you’re looking at four things specifically.
1. Encroachments. Anything crossing a property line is a problem. Most institutional lenders will not fund a deal with unresolved encroachments. The fix is usually one of: a registered easement, an encroachment agreement with the affected neighbour, removal of the encroaching structure, or title insurance that specifically covers the encroachment. None of those happen overnight. Flag encroachments to your underwriter immediately.
2. Easements. Common easements (hydro, utility, drainage) are usually fine. Unusual easements (a private right-of-way across the lot to reach a back property, a shared driveway, a sewer line crossing the building footprint) deserve a closer look. The location of the easement matters: an easement that runs through the area where a buyer wants to add a pool is a problem the buyer should know about before closing.
3. Setback compliance. Each municipality has zoning bylaws requiring minimum distances between structures and property lines. The SRPR shows the actual distances. If the house sits closer to the property line than the bylaw allows, you have a non-conforming structure. Most of these are grandfathered (existed before the current bylaw), and title insurance usually covers them, but verify.
4. Age of the survey. A survey doesn’t legally expire, but lenders and title insurers treat older surveys with caution. As a working rule, surveys older than 10 to 15 years typically need updating, particularly if visible changes have happened (additions, new sheds, new fences, pool installation). Many lenders accept an older survey paired with an owner’s declaration confirming no material changes since the survey date. Confirm with your underwriter.
Survey vs. title insurance
This is the question that comes up on almost every file. The short answer: they are different products that protect against different things, and one does not replace the other.
A survey shows physical reality on the ground. Title insurance is a contract that pays out if there’s a defect with the title or with the physical layout that creates a loss.
In practice, the Ontario market has shifted heavily toward title insurance as a substitute for a current survey. Most institutional lenders now accept a title insurance policy in lieu of an updated SRPR. The title insurer takes on the risk that an encroachment, setback issue, or other survey-related defect will cause a loss, and they pay the claim if it happens.
That doesn’t mean surveys are obsolete. Title insurance has limits. It pays you for losses; it doesn’t show you what’s actually on the property. If your client is planning to renovate, add a structure, or do anything that depends on knowing exact boundaries, a current survey is still the right tool. If the file is a straightforward refinance of a property the client has owned for ten years, title insurance is usually enough.
The practical workflow: ask the client for any existing survey. If one exists, read it. If it doesn’t exist or is very old, confirm with the underwriter whether title insurance alone is acceptable. For most institutional refinance deals, it is.
What an SRPR doesn’t tell you
Limits, same as the parcel register has.
- It doesn’t show you what’s registered on title. That’s the parcel register’s job. The SRPR shows easements approximately and references the instrument number, but for the actual easement language you need the registered instrument.
- It doesn’t show you what’s underground. Buried utilities, septic systems, underground oil tanks, foundations of demolished structures. None of that appears on a standard SRPR.
- It doesn’t show you municipal compliance unless the bylaw setbacks happen to be drawn on the plan. Zoning verification is a separate municipal inquiry.
- It doesn’t show you environmental issues. Contamination, flood plains, conservation authority restrictions. Other reports cover those.
- It doesn’t tell you the property’s market value. Lot size and dimensions affect value but the survey is not an appraisal.
- It’s a snapshot of one day. If the survey is from 2008 and the homeowner finished the basement, added a deck, and installed a pool in 2015, the survey is incomplete on its own.
How brokers actually use a survey
Three practical use cases.
- On a purchase file. Get the survey from the seller’s side if one exists. Read it. Note any encroachments, easements, or setback issues. Flag anything that could affect lender approval. If no survey exists or it’s old, decide with your underwriter whether title insurance is sufficient.
- On a refinance. Most refinance files run on title insurance now. Confirm with your underwriter. If the homeowner has an existing survey, it’s still worth reading for context, especially if there’s a future renovation or addition planned.
- When the client is planning changes. Renovations, additions, pools, sheds, new fences. Anything that depends on knowing exactly where the boundaries are. Recommend the client get a current survey. A few hundred dollars now saves disputes later.
What to do when you find a problem
- Encroachments: flag to your underwriter immediately. Likely fix is title insurance covering the specific encroachment, or an encroachment agreement registered on title.
- Easements you didn’t expect: cross-reference with the parcel register. Pull the actual easement instrument. Read the language to understand what’s permitted on the easement area.
- Setback violations: most are grandfathered and covered by title insurance. Verify with the lawyer or title insurer.
- Old survey, no current one: confirm the lender’s policy. Most accept title insurance. If the file requires a current survey, the buyer commissions one. Build the timeline into your closing schedule because a new survey takes one to three weeks.
- Suspect the survey is forged or altered: real SRPRs have a surveyor’s certificate signed by a licensed OLS and reference the underlying plans. If anything looks off, contact the surveyor whose name is on the document or contact AOLS to verify the surveyor’s licence.
The takeaway
Reading a survey is a skill that takes a few hours to develop and pays back on every transaction. The cost is small. The number of problems you’ll catch before they reach the underwriter is significant.
Build the habit on day one. Pull the survey. Look at the date. Find the encroachments and easements. Check the setbacks. Ask the questions before someone else asks them for you.
That’s the broker version of due diligence on the physical property. Combined with the parcel register, you’ve covered both what’s registered and what’s actually there.
