The Seller Property Information Statement (SPIS) in Ontario: Should You Complete One?

At some point in the listing process, many Ontario sellers are handed a form called a Seller Property Information Statement, or SPIS, and asked to fill it out. It asks detailed questions about the property's history — past water damage, renovations, known defects, and more. It feels routine. It isn't required, and it isn't risk-free either.

Whether to complete an SPIS is a genuinely case-by-case decision, and it's one of the more common questions sellers bring to a real estate lawyer before listing. Understanding what the form is, and isn't, for helps you make that decision with your eyes open.

What an SPIS Actually Is

An SPIS is a standard-form questionnaire, commonly presented to sellers by their real estate agent, covering things like known structural issues, past flooding or leaks, renovations and whether permits were obtained, environmental concerns, and the age and condition of major systems. It is completed by the seller, not the agent, and it's meant to give a prospective buyer information that isn't otherwise obvious from a walkthrough or a home inspection.

Completing an SPIS is entirely voluntary under Ontario practice. Nothing in the law requires an Ontario seller to fill one out, and declining to complete one is a legitimate, common choice.

The General Legal Backdrop: Caveat Emptor

Ontario resale home sales operate under the general common law principle sometimes summarized as "buyer beware" (caveat emptor). In broad terms, a seller isn't automatically obligated to volunteer every flaw in a property — buyers are expected to do their own due diligence, including a home inspection where appropriate.

That general rule has real limits, though. A seller generally cannot actively conceal a known defect, especially one that isn't discoverable on a reasonable inspection and that could make the property dangerous or unfit for habitation. Silence is treated differently from a false statement — which is exactly why the SPIS raises its own separate risk.

Why Completing an SPIS Can Create Liability

Once a seller voluntarily makes statements about the property — in an SPIS or anywhere else — those statements need to be accurate to the seller's actual knowledge. If a seller completes an SPIS and states something that turns out to be false, a buyer who relied on that statement may later have a claim, even in situations where the seller would have owed no disclosure obligation at all if they had simply said nothing.

This is the core tension many real estate lawyers flag: an SPIS can convert silence (which the law may excuse) into an affirmative representation (which the law holds you to). A seller who genuinely doesn't know the answer to a question, or isn't sure, should never guess just to fill in a blank.

Why Some Sellers Complete One Anyway

An accurate, carefully completed SPIS isn't purely a liability trap. Some sellers — and their lawyers — see real upside:

• It can build buyer confidence and support a stronger offer in some markets.
• Disclosing a known issue upfront, accurately, can actually reduce the odds of a later claim, compared to a buyer discovering it after closing and alleging concealment.
• It creates a clear written record of what the seller did and didn't know at the time of sale.

A Practical Approach for Sellers

Before You Decide

• [ ] Ask your real estate lawyer whether completing an SPIS makes sense for your specific property and situation.
• [ ] Review your own knowledge of the property honestly — including things a past owner or tenant may have told you.
• [ ] Understand that "I don't know" is a valid, and often the safest, answer to a specific question.

If You Do Complete One

• [ ] Answer only from your actual knowledge — never guess or assume.
• [ ] Don't let anyone else (including your agent) fill in answers on your behalf.
• [ ] Keep a copy, along with any supporting documentation (permits, repair invoices), for your records.

If You Decline

• [ ] Understand that declining doesn't remove your obligation to avoid active concealment of known, dangerous, non-discoverable defects.
• [ ] Be prepared to answer direct questions honestly if a buyer or their inspector raises something during the transaction.
