Buying a share of a family cottage, a semi-detached duplex, or a lot carved out of a larger parcel sometimes comes with a clause you won't see in an ordinary resale deal: a right of first refusal. It sounds protective, and it can be — but it also changes how freely a property can be sold, and by whom.

A right of first refusal (sometimes shortened to ROFR) gives someone — a co-owner, a family member, a former owner, a tenant — the ability to step into a sale before it happens, on the same terms a third party has already agreed to. If you're buying a property with one attached, or negotiating to have one included, understanding what it actually does — and doesn't do — matters before you sign.

This article explains how a right of first refusal works under Ontario contract law, where it commonly shows up in a residential purchase, and what tends to go wrong when the clause is poorly drafted.

What a Right of First Refusal Actually Means

A right of first refusal is a contractual promise, not an automatic legal entitlement — it exists only because someone agreed to grant it, usually in a deed, a co-ownership agreement, a lease, or a family arrangement. It gives the holder the right to match a bona fide offer the owner has already received from someone else, within a set window, before the owner can sell to that third party.

Critically, a ROFR does not let the holder force a sale, and it does not set a price on its own. It only activates once the owner has decided to sell and has an offer in hand.

How It Differs From an Option to Purchase

People often use "right of first refusal" and "option to purchase" interchangeably, but they work differently.

FeatureRight of First RefusalOption to Purchase
Who triggers itThe owner, by deciding to sellThe option holder, by exercising the option
PriceUsually whatever a third party has offeredUsually fixed or formula-based in advance
Can the holder force a sale?No — only matches an existing offerOften yes, within the option period
Common contextCo-ownership, family transfers, severed lotsLand assembly, development deals, leases

A right of first offer is a third, related concept: the owner must offer the property to the holder before shopping it to the market — the sequence runs the opposite direction from a right of first refusal.

Where These Clauses Commonly Show Up

What Happens When the Clause Is Triggered

  1. The owner receives a bona fide, arm's-length offer from a third-party buyer.
  2. The owner gives the ROFR holder notice of the offer's material terms — usually price, closing date, and any conditions.
  3. The holder has a defined window to decide whether to match the offer on the same terms.
  4. If the holder matches within the window, the sale proceeds with the holder as buyer instead of the third party.
  5. If the holder declines, or the window passes without a response, the owner is generally free to complete the sale with the original third-party buyer — often only on the same or similar terms already disclosed.

Common Drafting Problems That Cause Disputes

Because these clauses are often drafted outside a standard resale agreement — inside a deed, a family agreement, or a separate contract — they don't benefit from the years of refinement that standard-form purchase agreements have had. A lawyer reviewing the clause before you buy, or before you agree to grant one, can catch these gaps.

Frequently asked questions

Does a right of first refusal show up on the title of my property?

It can, if it's registered against title as part of a formal agreement, easement, or restrictive covenant. In other cases it exists only as a personal contractual right in a separate agreement and won't appear on a title search — which is itself a risk, since it may not bind a future purchaser who has no notice of it. A lawyer reviewing your purchase should confirm which situation applies.

Can I refuse to grant a right of first refusal if a co-owner asks for one?

Yes. A right of first refusal only exists if you agree to it in writing; nothing in Ontario law requires an owner to grant one. It's a negotiated term, common in co-ownership and family arrangements but not standard in an ordinary resale purchase between strangers.

What if I hold a right of first refusal and the owner tries to sell without telling me?

That's generally a breach of the agreement that created the right, and you may have legal remedies — though what's available depends on how the clause is worded and what agreement it lives in. This is a situation worth raising with a lawyer promptly, since delay can affect your options.

Is a right of first refusal the same as a right of first offer?

No. A right of first offer requires the owner to offer the property to the holder before marketing it to anyone else. A right of first refusal only requires the owner to let the holder match an offer that's already been received from someone else.
