A share sale can leave the tenant corporation unchanged on paper and still activate a commercial lease restriction. The controlling question is not only whether the tenant named in the lease changes. It is whether the lease defines a change in ownership or voting control as a transfer, assignment, or other event requiring the landlord’s prior consent.
This distinction matters because a buyer can acquire the operating company while the lease remains one of the business’s most important assets. If the parties assume that a share transaction avoids the lease, they may discover late that consent, financial disclosure, additional security, or a new guarantee is required. The broader transaction may be ready to close while the right to keep operating from the premises remains unsettled.
The full transaction framework appears in the Counsel Note: Selling a business does not automatically transfer the commercial lease. The corresponding business-sale commercial-lease preparation checklist identifies the documents and decisions to assemble before the consent process begins. Both route markers are approval-stage placeholders and must be replaced before release.
What the clause may treat as a transfer
A transfer clause may cover more than a conventional assignment from one tenant to another. Depending on its wording, it may also capture a direct or indirect change in control, a sale of voting shares, a transfer of a material ownership interest, an amalgamation, a reorganization, or a sale of substantially all business assets. Defined terms can expand the clause beyond the everyday meaning of “assignment.”
The operative effect is therefore different from the apparent effect. The apparent effect is that the same corporation remains tenant after a share sale. The operative effect may be that the people controlling that corporation have changed, which the lease treats as a consent event. A transaction label such as “share purchase” does not override the lease definition.
Why the clause changes the real transaction
If consent is required, the seller and buyer need to know what the request must contain, how much time the landlord has to respond, which costs are recoverable, and what conditions the landlord may impose. The landlord may ask for buyer financial information, a covenant from the new controlling party, additional security, or payment of review costs. Whether a particular request is permitted depends on the lease and applicable law; it should not be assumed.
The clause also changes the purchase agreement. The parties may need a consent condition, a covenant assigning responsibility for the application, a deadline, an allocation of landlord costs, and a stated consequence if consent is refused or arrives with unacceptable conditions. Without those terms, the buyer may be required to close without secure occupancy, or the seller may promise an outcome it cannot unilaterally deliver.
The seller’s release is a separate result
Even where the landlord consents, that consent does not necessarily release an existing guarantor or extinguish obligations that arose before closing. The consent document, assignment or assumption agreement, purchase agreement, and guarantee must be read together. A clean business-sale closing does not by itself create a clean lease exit.
Ontario’s Commercial Tenancies Act includes provisions concerning assignments, subleases, and consent. Those provisions do not eliminate the need to interpret the particular transfer definition, consent procedure, and guarantee in the signed lease. See Commercial Tenancies Act, RSO 1990, c L.7, ss. 23–26 (accessed July 27, 2026).
The practical review
Put the lease beside the proposed ownership chart. Identify the tenant, current voting and beneficial owners, proposed owners, and every intermediate entity. Mark the words that define transfer and control. Then record the required notice, consent standard, supporting information, fees, security, and timing. The result should be a closing instruction, not a general observation that consent “may” be needed.
Before signing, decide who will approach the landlord, what may be disclosed, what conditions are acceptable, whether the seller requires an express release, and what happens if the answer is late or commercially unworkable. DRG Law can review the lease against the proposed transaction and help frame those decisions. Discuss a business transaction with DRG Law.
Frequently asked questions
Does every share sale require landlord consent?
No. The answer depends on the lease language and the proposed ownership change. The review begins with the lease’s definitions and consent provisions.
Can the purchase agreement be signed before consent is obtained?
It can, but the agreement should state whether consent is a closing condition, who controls the process, which landlord conditions are acceptable, and what happens if consent is not obtained.
Does consent release the seller’s personal guarantee?
Not automatically. An express release should be requested and documented if ending the guarantee is part of the seller’s required outcome.
