Buying a newly built home or condominium in Ontario comes with statutory warranty protection, but that protection is only one part of your due diligence. You still need to review the purchase agreement, verify builder and warranty information, plan inspections, and keep clear records of anything incomplete or defective.
Ontario guidance explains that new homes and condominium units have warranties administered by Tarion. Protections are commonly described across one-year, two-year, and seven-year periods, covering issues such as poor workmanship, water penetration, and major structural defects. Exact eligibility and procedures depend on the circumstances, so use this guide as general information rather than legal, construction, mortgage, or claims advice. Review Ontario’s current new-home buying guidance before making decisions.
Quick summary
- Tarion administers Ontario’s new home warranty protection, while the builder remains central to correcting covered issues.
- The one-year, two-year, and seven-year periods address different types of problems.
- A warranty is not a guarantee that every concern will be repaired, and it does not replace an inspection or legal review.
- Before signing, check the builder, agreement, deposits, specifications, possession expectations, and warranty information.
- If a defect appears, photograph it, record dates and correspondence, notify the appropriate party, and check the current Tarion process promptly.
How the new home warranty works in Ontario
Ontario’s new home warranty is a legal protection connected to eligible newly built homes and condominium units. The builder has obligations to deliver the home in accordance with the agreement and applicable requirements, while Tarion administers the warranty protection and related process.
Warranty coverage does not make the purchase agreement unimportant. The agreement, schedules, specifications, upgrade selections, disclosure materials, and written communications may all help establish what you were promised and what you should expect at occupancy or possession. A real estate lawyer can explain contractual rights, while an inspector or other qualified professional can comment on technical conditions.
The 1-year, 2-year, and 7-year warranty periods
The table below is a practical overview, not a complete statement of eligibility, exclusions, claim requirements, or deadlines. Confirm the current rules for your home and situation through official sources.
| Period | Broad protection | Useful buyer action |
|---|---|---|
| One year | May address defects in workmanship and materials, subject to applicable requirements. | Keep a detailed list of visible deficiencies identified during inspections, occupancy, and early ownership. |
| Two years | May include specified concerns such as water penetration and other covered defects, depending on the issue. | Do not ignore leaks or moisture. Record where and when they occur and preserve builder communications. |
| Seven years | May apply to major structural defects, subject to the applicable definition and requirements. | Obtain appropriate technical advice when a concern could affect structural performance. |
These periods do not mean every problem discovered during that time is automatically covered. The defect must fit the applicable protection and process. Document concerns promptly rather than assuming the builder will accept every request.
What warranty protection does not replace
A new home warranty should be treated as one part of a larger buying plan. A newly built property can still have unfinished work, specification differences, installation concerns, or conditions requiring professional assessment.
Before signing, consider having a real estate lawyer review the purchase agreement. Before possession, consider a qualified home inspection where appropriate. Your lender or mortgage professional can address financing conditions, and the builder should explain construction-specific information that is unclear in the documents.
Separate three questions: what the agreement says, what the property physically shows, and what the warranty program may cover. A concern can involve one, two, or all three. A GTA home buying checklist can help organize the wider offer and due-diligence process, but it cannot replace specialist advice.
Before signing: a practical buyer checklist
- Identify the parties: Confirm the legal identity of the builder or seller, the project or property, and who will answer questions.
- Check warranty information: Ask how the home is enrolled for warranty protection and verify important details through current official sources.
- Read the agreement and schedules: Review price, deposits, included features, upgrades, allowances, specifications, timing, and termination terms with your lawyer.
- Keep deposit records: Save receipts, confirmations, amendments, and related correspondence.
- Clarify timing: Ask about estimated occupancy or possession dates, possible changes, notice procedures, and delays.
- Plan inspections: Determine whether an independent inspection can be arranged before possession and what access is available.
- Record promised finishes: Keep specifications, colour selections, appliance details, upgrade confirmations, and written changes together.
- List unanswered questions: Request written clarification rather than relying on informal statements.
For an agreement ready to be signed, focus on understanding its obligations rather than relying only on the warranty. Review what to review before signing an Ontario offer, then ask a lawyer to explain the specific document.
Inspections, pre-delivery review, and possession
A pre-delivery review lets you observe the home, compare visible work with the agreement and specifications, and identify items requiring attention. It cannot guarantee that every concealed condition will be found.
Bring your agreement, specifications, and upgrade list. Photograph visible damage, unfinished work, moisture concerns, damaged finishes, and items that differ from what was agreed. Record the date, location, description, and any discussion about the issue.
Keep emails, service requests, inspection reports, photographs, and builder responses. If a concern appears after possession, record when it was first noticed and whether it changes with weather, use, or location. This evidence helps explain the issue, although it does not by itself establish coverage.
What condominium buyers should know
Condominium buyers need to consider both the individual unit and the common elements. The Canada Mortgage and Housing Corporation’s Ontario fact sheet states that developers of new residential condominiums must provide home warranty protection and be registered with Tarion. It also distinguishes common areas, which are owned by the condominium corporation for warranty purposes. See CMHC’s Ontario condominium fact sheet for this distinction.
Before signing a pre-construction condominium agreement, review the disclosure statement, declaration, description, budget information, specifications, occupancy arrangements, maintenance responsibilities, and rules with your lawyer. Ask how unit deficiencies will be documented and how common-element concerns will be handled.
When a defect appears: what to do next
- Describe the issue: Note what happened, where it occurred, when you noticed it, and whether it is recurring.
- Document the condition: Take dated photographs or videos and keep reports, receipts, and correspondence.
- Notify the appropriate party: Use the builder’s documented communication channel and keep proof of delivery.
- Check the current process: Review current Tarion guidance for applicable forms, timing, documentation, and dispute procedures.
- Get specialist advice: A lawyer can discuss contractual rights, while an inspector, engineer, or other specialist can address technical concerns.
Do not assume an issue will be accepted simply because it appeared during a warranty period. The defect, evidence, agreement, applicable requirements, and timing can all matter.
Where a real estate professional fits into the process
A real estate professional can help identify suitable properties, organize showings or listing information, prepare offer questions, and coordinate communication among the buyer, builder, lender, inspector, and lawyer. This can be especially useful for first-time buyers comparing a resale home with a newly built property.

Frequently asked questions
Does every new home in Ontario come with a Tarion warranty?
Ontario guidance states that new homes and condominium units come with warranties and protections provided by the builder and administered by Tarion. Confirm that the specific property and transaction are eligible before signing.
Does a new home warranty cover poor workmanship?
Poor workmanship is among the issues Ontario guidance identifies as potentially covered. Coverage is not automatic for every imperfection, so document the concern and check the current official process.
Does the warranty cover a new condominium’s common elements?
Condominium warranty questions can involve both the unit and common elements. Ask your lawyer or condominium representatives how a particular concern should be reported.
Should I hire an inspector for a newly built home?
Consider an independent inspection where appropriate. Warranty protection does not replace technical observations, and an inspector may identify visible concerns that should be documented.
Can a Realtor review my purchase agreement?
A Realtor can explain transaction context, identify questions, and coordinate with other professionals. A real estate lawyer should explain the agreement’s legal effect.
Conclusion: treat warranty protection as one part of your buying plan
Ontario’s new home warranty provides important protection through commonly described one-year, two-year, and seven-year periods. The strongest approach is to understand the framework, verify the builder and documents, compare the completed home with the agreement, arrange appropriate inspections, and preserve a clear record of concerns.
