Key takeaways
  • A condition must be waived or performed by the agreed time, and until then the deal is not binding on you.
  • Once every condition is waived, the agreement is firm and binding.
  • A seller with a conditional deal can keep looking at other offers, but the first buyer gets a set time to waive its conditions.

A condition is a term that must be dealt with before your offer becomes a firm deal. Buyers often use them to protect themselves while they arrange a mortgage or have the home inspected.

This article walks through the conditions people commonly use in Ontario, how deadlines and waivers work, and how a seller's escape clause can affect you. Your actual wording matters a great deal, so treat this as a guide to the questions to ask.

What a condition does

Conditions such as a satisfactory home inspection must be waived or performed by the agreed time before the deal becomes binding, and they must be used in good faith. Depending on how the condition is worded, if it is not met the buyer may terminate or the contract may end automatically, with the deposit returned.

A conditional agreement is not final and binding until all its conditions are met or waived. Once all conditions are waived, the agreement is firm and binding.

Conditions buyers commonly use

Which conditions make sense depends on the property and your finances. Each one should be written clearly, with what must happen, by when and who can waive it.

Permits and other things to check during the condition period

Use the condition period to look into the property, not just the building. A building permit is required before most construction, additions, renovations and changes of use, and the municipal building department can confirm what permits exist for a property. Finding out whether proper permits were obtained for any renovations is part of a sensible buyer's checklist.

If the home is rented, special rules apply to whether the tenant can be asked to leave. A seller may give an N12 notice only for a residential complex of no more than 3 units or a condominium unit, and the purchaser must in good faith need the unit for their own use or that of certain family members or a caregiver. Ask a lawyer before relying on a vacant-possession promise.

Deadlines, waivers and extensions

Every condition has a deadline in the agreement. If you do nothing, what happens next depends on the exact wording: you may be able to terminate, or the agreement may end automatically. If you are satisfied, you can waive the condition before the deadline, and once all conditions are waived the agreement is firm and binding.

Be careful with waivers. Once all conditions are waived, you are bound. If you need more time, for example because the lender or inspector is delayed, raise it early. Whether that is possible depends on the seller's agreement and the wording, so speak to your lawyer or agent before the deadline, not after.

Withholding your deposit while you wait for a condition can itself breach the agreement. In one RECO example, a buyer who held back a deposit due on acceptance until after an inspection may have given the seller grounds to terminate and seek damages.

How a seller's escape clause affects you

A seller who has accepted a conditional offer may still consider other offers. The seller protects itself with an escape clause that requires notice to the first buyer and gives that buyer a set time, for example 48 hours, to waive or satisfy its conditions.

If the first buyer waives or fulfils its conditions within the deadline, the seller must sell to that buyer on the original terms. A backup offer should therefore be made conditional on the first deal ending.

With competing offers, the seller may negotiate with one buyer while setting others aside and does not have to take the highest price. A buyer with a written offer is entitled to know the number of competing offers, but not their amounts or conditions.

What to do before you submit your offer

Frequently asked questions

What happens if my inspection condition is not satisfied?

Depending on how the condition is worded, you may be able to terminate or the contract may end automatically, with the deposit returned. Check your wording and act before the deadline.

Can the seller accept another offer while mine is conditional?

Yes. A conditional agreement is not final until the conditions are met or waived, so the seller may consider other offers, usually using an escape clause that gives you a set time, such as 48 hours, to waive or satisfy your conditions.

If I waive my conditions, can I still back out?

Once all conditions are waived, the agreement is firm and binding. Backing out after that may expose you to claims, so get advice first.

Can I get more time on a condition?

Whether you can get more time depends on the seller and the wording of your agreement. Conditions otherwise need to be waived or performed by the agreed time. Raise it with your lawyer or agent well before the deadline.
