If you’re a real estate investor in Ontario, the difference between a conditional offer and a firm offer can mean the difference between a successful deal and a legal disaster. Whether you’re buying your first rental property or flipping your fifth house, understanding the legal implications of conditional vs. firm offers is non-negotiable. 

In this comprehensive guide, we’ll explain: 

• What conditional and firm offers mean in Ontario real estate 

• When and why investors use each 

• The legal risks and protections 

• What happens if conditions aren’t met — or worse, if a buyer or seller walks away 

1. What Is a Conditional Offer in Ontario Real Estate? 

A conditional offer is an Agreement of Purchase and Sale (APS) that is dependent on specific conditions being fulfilled within a stated period (usually 3–10 business days). 

Common Conditions in Real Estate Offers: 

• Financing Condition: The buyer must secure a mortgage or financing. 

• Home Inspection Condition: The property must pass a professional inspection. 

• Sale of Buyer’s Property Condition: The buyer must sell their existing home first. 

• Status Certificate Review (Condos): For condo purchases, the buyer’s lawyer must review the condo corporation’s financials and bylaws. 

Until the conditions are met and waived in writing, the deal is not legally binding. 

2. What Is a Firm Offer in Ontario? 

A firm offer is an unconditional agreement to purchase the property. There are no “outs.” Once accepted, the deal is binding and enforceable, regardless of financing, inspection issues, or changes in the buyer’s circumstances. 

Firm offers are typically used: 

• In competitive bidding wars 

• By experienced investors confident in the property’s condition 

• When financing is already secured 

3. Legal Status: Conditional Offers Are Not Binding — Until Conditions Are Waived 

Under Ontario law, a conditional offer becomes binding only when all conditions are waived or fulfilled by the deadline specified in the APS. 

For example: If you place a conditional offer pending financing approval within 5 days, and the lender declines you, the offer can be terminated without legal penalties. 

But if the condition isn’t waived or fulfilled on time, the offer automatically lapses — unless the deadline is extended by mutual agreement. 

4. Legal Status: Firm Offers Are Binding the Moment They Are Accepted 

There is no “grace period” or escape clause in a firm offer. Once signed and accepted: 

• The buyer is legally obligated to complete the transaction. 

• The seller has the right to enforce the contract through the courts. 

• Backing out could result in a lawsuit for damages or lost profits. 

Important for investors: You may still need financing or inspections — but with a firm offer, you assume all risk if problems arise later. 

5. Risks of a Firm Offer: When Things Go Wrong 

While firm offers make you a more attractive buyer, they come with serious legal exposure, especially if: 

• You fail to secure financing after making a firm offer. 

• You discover major defects after waiving inspection rights. 

• You can’t close on time, and the seller sues for breach of contract. 

Example Scenario: 

You make a firm offer on a triplex. After the deal is accepted, your bank declines the mortgage, and you can’t close. The seller sues you for the difference if the property later sells for less — plus legal fees and carrying costs. 

6. Risks of Conditional Offers: You Might Lose the Property 

Sellers generally prefer firm offers, especially in hot markets. By submitting a conditional offer: 

• You risk being outbid by a buyer with a firm offer 

• Your offer may be rejected outright 

• The seller may use your offer to leverage others 

For investors, this can mean missing out on time-sensitive deals — like below-market properties or power-of-sale listings. 

7. Waiving Conditions: It Must Be in Writing 

To firm up a conditional offer, you must waive each condition in writing, signed by all parties. This is often done using Form 123 – Notice of Fulfillment or Waiver. 

Verbal waivers are not legally binding. 

Pro tip: Always have your real estate lawyer review waivers to ensure they’re legally enforceable and protect your interests. 

8. Can You Back Out of a Firm Offer? Only With Legal Consequences 

Once a firm offer is accepted, you cannot walk away without consequences. The seller can: 

• Keep your deposit (typically 5% of the purchase price) 

• Sue for damages if the resale value is lower 

• Force the sale through specific performance (in rare cases) 

The courts in Ontario side heavily with contract enforcement in real estate. Judges are unlikely to sympathize if you made a firm offer without due diligence. 

9. Should Real Estate Investors Use Firm or Conditional Offers? 

Use a Firm Offer When: 

• You’ve already secured financing 

• You’ve done a pre-inspection or are buying as-is 

• You want to win a bidding war 

• You’re comfortable taking on risk 

Use a Conditional Offer When: 

• You need time to confirm financing or partners 

• You’re buying a unique or distressed property 

• You’re investing long-distance and need due diligence 

• You want a legal safety net to exit the deal 

Investor Tip: In slower markets, conditional offers are more likely to be accepted. In bidding wars, firm offers often win — but know your legal risk.
