If you’re purchasing a pre-construction home in Ontario without a Realtor, the lawyer review period becomes your most important safeguard. Builder agreements are drafted by the builder’s legal team—not yours—which means the contract naturally favors the builder’s financial and legal interests.
To protect yourself, you must understand the key clauses, potential risks, and non-negotiable protections that should be in place before you sign.
This guide breaks down the essential items you and your lawyer must review to avoid costly surprises at closing.
1. Development Charge Caps: The Most Critical Financial Protection
Municipal development fees can increase significantly between the day you sign and the day your home is ready. Without a cap, you could be forced to pay thousands more at closing.
What to Ask Your Lawyer to Confirm
-
Your contract must include a Cap on Development Charges / Levies.
-
The cap should be a specific number, not vague language.
-
A reasonable cap is often between $3,000–$10,000, depending on the builder.
Why It Matters
Development fees in Ontario have jumped dramatically in recent years. A $5,000 levy at signing can easily rise to $20,000–$30,000 by occupancy. With no cap, every dollar of that difference becomes your responsibility.
2. Assignment Rights: Your Safety Valve If Life Changes
Over multi-year build periods, life happens—job changes, financial changes, moving provinces, growing families, or unexpected setbacks.
Having an Assignment Clause lets you sell your contract before the unit is complete.
What Your Lawyer Should Verify
-
Whether assignment is permitted at all.
-
The assignment fee (commonly $2,500–$5,000).
-
That the contract states:
“Consent to assign shall not be unreasonably withheld.”
Why It Matters
Without assignment rights, you are locked into the deal—even if your circumstances force you to move or sell.
Assignment flexibility protects you from:
-
Financial hardship
-
Relocation
-
Rising interest rates
-
Delays in construction
3. Tarion Critical Dates, Delays & Compensation
Every new-build contract in Ontario must include the Tarion Addendum, managed by Tarion. This addendum outlines your Critical Dates, including:
-
Firm Occupancy or Closing Date
-
Outside Closing Date
-
Extensions the builder is allowed
-
Eligibility for compensation
What Can Go Wrong
Some contracts include vague language allowing the builder to delay construction multiple times without penalty. This can leave you paying rent for months longer than expected.
What Your Lawyer Should Confirm
-
Exact dates and definitions of Firm vs. Outside Closing
-
Whether the builder can extend dates multiple times
-
Your eligibility to receive:
Delayed Closing Compensation (up to $7,500)
Why It Matters
If the builder fails to follow Tarion rules, you may be owed compensation. Knowing these timelines in advance prevents unpleasant surprises.
4. Hidden “Adjustments” on Closing: The Costs Most Buyers Miss
Builder agreements often include extra charges called Adjustments. These can add thousands to your final bill—unexpectedly.
Common Hidden Fees Your Lawyer Should Look For
-
Utility meter installation (Hydro, Water, Gas)
-
Tarion Enrollment Fee ($600–$2,000)
-
Education levies
-
Driveway paving charges
-
Tree planting fees
-
Landscape charges
-
“Administrative fees”
-
“Lawyer’s Blue Box Fee” (yes—some builders charge this)
Why It Matters
Many buyers budget only for their mortgage and down payment. But closing adjustments can easily add $5,000–$15,000 depending on the builder.
A good lawyer will try to:
-
Cap these charges
-
Eliminate unnecessary ones
-
Clarify vague cost descriptions
5. Appraisal Protection: Guarding Against Market Drops
Buying pre-construction means betting on the market 2–4 years into the future. If home prices fall, your lender may appraise the property below your purchase price.
This creates an Appraisal Gap, where the bank lends less and you must cover the difference in cash.
What Your Lawyer Should Explain
-
Builders rarely allow a financing or appraisal escape clause
-
You must be financially prepared for a market downturn
-
Your deposit structure and closing funds must be secure
Smart Buyer Strategy
Ask your lawyer whether it’s possible to add language supporting:
-
Mortgage pre-approval flexibility
-
Additional time for securing financing
-
The ability to assign the property if financing fails
Even if your builder refuses these clauses, understanding the risk helps you plan appropriately.
6. Builder Reputation & Warranty Coverage (Often Overlooked)
Not all builders are equal. Before signing, research the builder’s history with Tarion warranty claims, construction quality, and customer reviews.
What Your Lawyer Can Check
-
Past lawsuits
-
Homeowner disputes
-
Large numbers of warranty claims
-
Cancellation history (some builders cancel projects during downturns)
Why It Matters
A poor-quality builder can leave you with:
-
Deficiencies
-
Delayed construction
-
Poor workmanship
-
Warranty battles
Choosing a reputable builder saves money and stress.
7. Material Changes: Make Sure the Builder Cannot Alter Your Home Without Consent
Some agreements allow the builder to make substantial changes, such as:
-
Floor plan adjustments
-
Removing windows
-
Changing finishes
-
Reducing square footage
Your lawyer should ensure the contract restricts the builder from making material changes without buyer approval.
Your Lawyer Review Window Is Your Only Real Protection
When buying directly from a builder, the contract is written to protect the builder—not you. This is why the lawyer review period is the most critical stage of the entire purchase.
A strong legal review may help you:
-
Save tens of thousands
-
Avoid unfair surprises
-
Maintain flexibility
-
Understand your financial exposure
-
Protect your deposit and closing budget
