Do You Need a Survey When Buying a House in Ontario? Survey vs. Title Insurance Explained
Your offer got accepted. Great. Then your lawyer’s office sends over a list of things to sort out, and somewhere on it is a question: survey, title insurance, or both?
Most buyers have maybe a day or two to answer, and nobody has ever explained the difference to them. So let’s fix that.
So, is a survey required?
Usually not. A lot of people close on a house in Ontario without ever ordering a new one. Your lender or your lawyer might ask for one, and sometimes they’re happy with something else, but there’s no blanket rule saying every buyer must have a fresh survey.
That doesn’t mean it’s a waste of money, though. Whether it’s worth it depends on the house, and on how much uncertainty you’re comfortable carrying into your first few years of owning it.
What a survey actually tells you
A survey is a measurement. An Ontario Land Surveyor goes to the property, finds the boundary markers, measures what’s on the lot, and draws it all up. What you get back shows where your lot lines really run, where the house, garage, shed, and deck sit compared to those lines, and any easements crossing the land. If a neighbour’s fence or driveway has crept over, it shows that too. So does your own stuff creeping over theirs.
Think of it as seeing the property as it exists today, not as the paperwork describes it.
What title insurance does (and doesn’t)
Title insurance is a one-time policy that your lawyer usually sets up at closing. It’s there to protect you from certain legal problems with ownership, things like fraud, forged documents, or mistakes in the public records. If one of those problems turns up later, the policy can help.
What it isn’t is a measuring tool. It won’t tell you where your fence is. It won’t tell you the neighbour’s garage is two feet onto your side. And many policies carve out problems that an accurate survey would have caught, which surprises people. Coverage differs between insurers and between policies, so ask your lawyer to point out what’s excluded on yours. It’s a short conversation and a useful one.
The two side by side
| Survey | Title insurance | |
|---|---|---|
| What it is | A physical measurement of the property | An insurance policy |
| What it covers | Boundaries, buildings, easements, encroachments | Certain ownership and title risks |
| Who provides it | An Ontario Land Surveyor | An insurer, arranged by your lawyer |
| When it helps | Before you close, because you see real conditions | After closing, if a covered problem appears |
They overlap a little around the edges, but neither one replaces the other. A survey shows you what’s there. Insurance pays out if something goes wrong. Different jobs.
When a new survey makes sense
Some situations just call for one:
- There’s no survey, or it’s ancient. A drawing from the 1980s doesn’t know about the deck somebody added in 2015 or the fence replaced last spring.
- Things have been built or changed. Additions, garages, pools, and sheds all change the picture.
- You want to build something yourself. If a garage, an addition, or a walkout is in your plans, you’ll want to know what the lot really allows before you pay a designer.
- The lot looks odd. Hedges that wander, a driveway that seems too close to the neighbour’s, a fence that clearly isn’t straight. Trust that instinct.
- The property is rural, irregularly shaped, or has a murky history. Old severances and strange lot shapes are where surprises tend to hide.
And sometimes it’s simpler than all that. Some buyers just want to be sure before they sign. That’s a perfectly good reason.
When you can probably skip it
If the seller has a recent survey and nothing has been built or changed since, a copy of that survey, often paired with a statement from the seller confirming nothing’s changed, is frequently good enough for lawyers and lenders. Your lawyer will tell you whether it works in your case.

Watch the clock
Conditions periods are short and closing dates don’t move. Surveys need to be booked, measured, and drafted, which takes time. If you think you might want one, bring it up with your lawyer and your surveyor right away, not the week before closing. This breakdown of how long a land survey takes in Ontario will help you plan around your dates.
Cost is the other thing everyone wonders about, so here’s what a land survey costs in Ontario. Compare that number with what a boundary problem could cost you later and the decision usually gets easier.
What a survey can catch
The kinds of things that show up are rarely dramatic, but they’re annoying and sometimes expensive:
- A neighbour’s shed sitting partly on the lot you’re buying
- An easement running right through the spot where you wanted a pool
- A deck or addition that’s too close to the lot line
- A fence everyone treats as the boundary that isn’t
Plenty of homeowners don’t find any of this out for years, usually when they go to sell, build, or argue with the neighbour over a fence. Learning about it before closing gives you options: you can negotiate, ask the seller to fix it, or walk away.
A few questions to ask yourself first
- Is there a recent survey for this property?
- Has anything been built or changed since it was done?
- Am I planning work that depends on exact lot lines or setbacks?
- What will my lawyer and lender accept in place of a new survey?
- How many days until my conditions come off?
If you can’t answer most of these with confidence, that’s a decent sign you should talk to a surveyor.

Frequently Asked Questions
Do I need a survey to buy a house in Ontario? Usually it isn’t required by law, but plenty of buyers get one, especially when there’s no recent survey or the property has changed. Your lawyer and lender may have their own requirements.
Is title insurance enough on its own? It protects against certain ownership risks, but it doesn’t measure the property or show boundaries and encroachments. Policies differ in what they exclude, so check with your lawyer.
Can I use the seller’s old survey? Often, yes, as long as nothing has changed since it was done. Your lawyer can confirm whether it’s acceptable.
What does a survey show that title insurance doesn’t? Where the lot lines are, where buildings and fences sit, and whether any easements or encroachments affect how you can use the land.
When should I order one? As soon as possible after your offer is accepted. Surveys take time and conditions periods are short.
