Why This Matters

For many businesses, a commercial lease is a core asset. Losing the right to renew a lease can mean losing a location, customers, financing opportunities, or even a planned sale.

This Insight explains how lease renewal disputes arise in real life, how courts deal with them, and how better drafting and internal processes can prevent costly litigation.

1. The Common Problem We See in Practice

Commercial lease renewal disputes often start the same way.

The business believes it has renewed its lease, but the landlord later takes the position that the renewal was never properly exercised. By the time the issue becomes clear, the renewal deadline has passed, and the business has lost the right to stay.

This usually happens because:

• The business misses the renewal deadline, often because key dates were unclear or tracked informally.
• Renewal terms are discussed by email, and the business assumes that the discussion is enough.
• The business waits to negotiate rent first, while the renewal deadline quietly expires.
• Small rent or expense disputes are treated as minor, without realizing the lease requires “no default” to renew.
• The business assumes that silence from the landlord means acceptance.

When this goes wrong, the consequences can be severe: loss of location, disruption to operations, reduced enterprise value, and failed financing or sale transactions.

2. A Real Case: What Happened in Court

2324702 Ontario Inc. v. 1305 Dundas W Inc., 2020 ONCA 353

A tenant operated a restaurant and event space in Toronto. The lease allowed the tenant to extend the lease for another five years, but only if the tenant gave clear written notice within a specific two-month window.

During that window, the tenant and landlord exchanged emails discussing renewal and rent. However, the tenant never sent a clear written notice formally exercising the renewal right, as the lease required.

The tenant later fell behind on rent. The landlord terminated the lease.

The courts ruled that:

• Discussing renewal by email was not enough.
• The lease required a clear and formal renewal notice, delivered on time and in the manner specified.
• The landlord’s silence did not amount to acceptance.

The court refused to grant relief, even though the outcome was harsh. The tenant lost the renewal right and could not rely on fairness or sympathy to undo the mistake.

3. Why This Happens

Most lease renewal disputes are not caused by bad intentions. They happen because informal business habits collide with strict legal rules.

Common causes include:

• No single person is responsible for tracking renewal deadlines.
• Renewal is treated as part of rent negotiations, rather than a separate legal right that must be exercised on time.
• Emails or discussions are mistaken for a formal renewal.
• Minor disputes are underestimated, even though they can legally block renewal.

In litigation, courts focus less on what the parties intended and more on whether the tenant followed the lease exactly.

4. How These Disputes Are Prevented in Practice

From a litigation perspective, prevention comes down to discipline and clarity.

Effective prevention typically involves:

• Treating renewal deadlines like hard legal cut-offs, not flexible business milestones.
• Sending a formal renewal notice early, exactly as required by the lease, even if rent discussions continue.
• Drafting leases so that renewal mechanics, notice methods, and default conditions are clear and workable.
• Aligning internal processes so legal, finance, and operations are not working in silos.

Once a renewal deadline is missed, legal remedies are limited and uncertain. Courts are generally reluctant to fix mistakes that could have been avoided with timely, clear action.

Final Thought

Most lease renewal disputes are avoidable. They arise when informal practices are applied to formal legal rights. Clear drafting and disciplined internal processes are the most effective ways to prevent these disputes before they reach court.
