Ontario does not have one universal home inspection contingency period. The deadline comes from the inspection condition in your signed Agreement of Purchase and Sale, including its wording, date, time, notice requirements, and stated consequences.
Ontario buyers may also hear this described as a home inspection condition or an offer conditional on a home inspection. Whatever phrase is used, the signed agreement controls. Once your conditional offer is accepted, treat the inspection deadline as a contract date, not a general estimate.
What Controls the Home Inspection Contingency Period in Ontario?
Your signed agreement controls the inspection condition. It may specify a calendar date, time of day, delivery method for notice, and what must happen before the condition is fulfilled, waived, or otherwise addressed. The exact effect depends on the wording and circumstances of your transaction.
Do not rely on a verbal statement that you have “about five days” or on a general online rule. Ontario’s home-buying guidance explains that inspection results may lead to several decisions, but your agreement determines how those decisions must be handled. Ask your own realtor or real-estate lawyer to interpret the clause.
What to Check in the Agreement of Purchase and Sale

Read the inspection condition as soon as the offer is accepted. If any wording is unclear, ask your realtor or lawyer rather than asking the inspector to interpret the contract.
- Condition wording: Identify what the buyer must be satisfied with and whether the clause refers to an inspection, report, or another requirement.
- Deadline: Record the exact date and time.
- Notice method: Check who must receive notice, how it must be delivered, and whether written confirmation is required.
- Required action: Determine whether you must provide notice, waive the condition, fulfill it, or take another step.
- Consequences: Ask what may happen if the deadline passes without the required action.
Keep the signed agreement, amendments, appointment confirmation, report, and professional contact details together. This reduces the risk of relying on an outdated draft or informal message.
A Practical Timeline After Your Conditional Offer Is Accepted
1. Review the condition immediately
Locate the executed agreement and highlight the inspection condition. Confirm the deadline with your realtor and ask what must be completed before it expires. Booking an inspection or receiving a report does not automatically satisfy the condition.
2. Book the pre-purchase inspection promptly
Provide the property address, type, access details, and contractual deadline when arranging the inspection. Ask about appointment availability and report timing, leaving enough time to read the findings and obtain advice.
ASM provides certified residential inspections across Toronto and the GTA, including pre-purchase inspections. Its published residential scope includes accessible structure, roofing, exterior, plumbing, electrical, heating, cooling, insulation, and interior components. Buyers comparing inspectors can also review these pre-purchase home inspection mistakes to avoid.
3. Understand what the inspection can and cannot establish
A residential home inspection assesses visible and accessible components within the agreed scope. It can document observed deficiencies, safety concerns, maintenance needs, and signs requiring further investigation. It cannot guarantee that every defect will be found or determine whether your contract permits a particular response.
An inspection does not replace legal, title, zoning, environmental, or specialist advice. If the report identifies a structural concern, specialized system, or inaccessible area requiring further evaluation, ask the appropriate professional about next steps.
4. Review the findings and ask focused questions
When the report arrives, separate findings into urgent safety or moisture concerns, significant defects, routine maintenance, and items needing specialist follow-up. Ask what was observed, where it was observed, what limitations applied, and whether further evaluation is recommended.
ASM states that its residential service includes a same-day PDF report. This can help when the decision window is short, but same-day delivery does not guarantee enough time to satisfy every contract requirement. The appointment, report review, advice, and required notice must still fit the written deadline.
5. Discuss your options before the deadline
Contact your realtor promptly and consult your lawyer when you need advice about contractual rights, wording, notice, or consequences. Depending on the agreement, possible responses may include asking the seller to make repairs, accepting a defect, requesting a price adjustment, or deciding not to buy. These are not automatic outcomes.
Who Handles Each Part of the Decision?
| Person | Primary role |
|---|---|
| Inspector | Assesses observed, visible, and accessible conditions within the agreed scope and explains the report. |
| Buyer | Reviews findings, identifies priorities, asks questions, and decides what property risk is acceptable. |
| Realtor | Helps communicate transaction decisions and discuss practical negotiation steps. |
| Real-estate lawyer | Advises on contract wording, notice, amendments, and legal consequences. |
The inspector should not tell you that a condition can be extended, waived, or terminated. Those questions concern the agreement and belong with your realtor or lawyer.
Home Inspection Deadline Checklist
- Locate the signed Agreement of Purchase and Sale and amendments.
- Highlight the condition, exact deadline, and notice method.
- Confirm what must be completed before the deadline.
- Book the inspection and provide timing details.
- Ask when the report is expected.
- Review safety concerns, moisture indicators, defects, limitations, and follow-up recommendations.
- Contact your realtor or lawyer before the final hours if you have concerns.
- Confirm that any required notice was delivered correctly.
Common Timing Mistakes to Avoid
Assuming a standard number of days: Use the written date and time in your transaction.
Booking too late: A late appointment leaves less time to read the report, obtain specialist input, or discuss options.
Relying only on a seller’s report: Existing documentation may be useful background, but it does not necessarily answer your questions about the property or your intended use.
Waiting until the final hours: Your realtor and lawyer need time to explain the available process. The inspector cannot extend the deadline or decide what notice is legally effective.
What Changes for New Construction or Firm Offers?
New construction still requires careful attention to the agreement and timing. An inspection can document accessible conditions and incomplete work, but it does not itself determine warranty rights or legal remedies. For more context, see this guide to new construction home inspections.
A firm offer does not contain the same inspection condition as a conditional offer. If you are considering an inspection after making or accepting a firm offer, do not assume it creates a right to renegotiate or withdraw. Ask your realtor or lawyer what options remain under the specific agreement.
Frequently Asked Questions
Is there a standard five-day home inspection contingency period in Ontario?
No. The signed Agreement of Purchase and Sale controls the condition, deadline, notice requirements, and consequences.
Can a buyer extend the deadline?
Do not assume an extension is automatic. Ask your realtor or lawyer whether a change is possible and how it must be documented.
What if the report arrives close to the deadline?
Review it promptly and contact your realtor or lawyer immediately. Ask the inspector about findings, but ask your legal or real-estate professional how the deadline applies.
Does a seller’s report replace the buyer’s inspection?
Not necessarily. Discuss its age, scope, limitations, and relevance before relying on it.
Who explains the legal consequences of missing the deadline?
Your real-estate lawyer should explain legal consequences and contract wording. Your realtor can help with communication, while the inspector explains property conditions.
Conclusion: Treat the Deadline as a Contract Date
The home inspection contingency period in Ontario is not a province-wide number. Your signed agreement sets the condition, deadline, notice process, and consequences. Identify those details immediately, arrange the right pre-purchase inspection, review findings promptly, and involve your realtor or lawyer before making a contract-related decision.
