Commercial Lease Disputes

A commercial lease is a business contract with property at its centre, and disputes under it can threaten a tenant's business or a landlord's income quickly. We act for landlords and tenants in disputes about rent, defaults, termination, lockouts and the steps each side can take.

Common situations

  • Unpaid rent or additional rent, and the landlord’s response
  • Lockouts and disputes over the landlord’s right to re-enter
  • Distress (seizure of the tenant’s goods for rent)
  • A tenant leaving before the end of the term, or going bankrupt
  • Disputes over operating costs, repairs and the use of the premises
  • Assignment or subletting without the landlord’s consent
  • Claims against personal guarantors and indemnifiers
  • Urgent motions to restore or prevent possession

How these disputes work

Commercial leases in Ontario are governed mainly by their own terms, by the general law of contract, and by the Commercial Tenancies Act. Residential tenancy rules and the Landlord and Tenant Board do not apply. Two points come up often:

  • Remedies can be inconsistent with each other. A landlord may have to choose between treating the lease as continuing and ending it, and the choice affects what can be claimed later.
  • Self-help has rules. Re-entry and distress are available only in defined circumstances and must be carried out properly.

Urgent relief

When a lockout, a threatened termination or the removal of goods would cause harm that money cannot repair, either side can ask the court for an urgent injunction. The court considers whether there is a serious issue to be tried, whether irreparable harm would result, and the balance of convenience. The party asking usually must undertake to pay damages if the order proves unjustified.

What happens next

  1. Read the lease and any amendments, guarantees and default notices.
  2. Confirm the timeline: what is owed, what notices were given, and what each side has done since the default.
  3. Choose the remedy carefully, because some steps cannot be undone.
  4. Act promptly, especially where a business may close or goods may be removed.

Questions we are often asked

Can a commercial landlord change the locks?
In some circumstances. The Commercial Tenancies Act and the lease can give a landlord a right to re-enter for unpaid rent, but the steps must be taken properly, and an improper lockout can expose the landlord to a claim and to a court order restoring the tenant to the premises.
What is distress?
A landlord's remedy of seizing and selling a tenant's goods on the premises to recover unpaid rent. It is subject to strict rules, and a landlord who has already ended the lease generally cannot also use it. The choice between remedies matters.
The tenant has left before the end of the lease. What can the landlord claim?
That depends on how the landlord responds to the tenant's departure and on the lease. The options include keeping the lease alive, ending it and claiming damages, or re-letting on the tenant's account, and each has different consequences. Get advice before acting.
Is a personal guarantee of a lease enforceable?
Generally, yes, according to its terms. Whether a guarantor remains liable after the lease is amended, assigned or ended depends on the wording of the guarantee.
Can I get an urgent court order in a lease dispute?
Yes, in genuinely urgent cases. The court considers whether there is a serious issue to be tried, whether the party asking will suffer harm that money cannot repair, and which side would suffer more from the order being granted or refused.
