Commercial Real Estate Disputes in Ontario: Your Legal Rights and Options

Common types of commercial real estate disputes in Ontario

Commercial lease disputes

Lease disputes are the most frequently litigated category of commercial real estate conflict. Commercial leases are complex documents that govern the relationship between landlord and tenant over periods that can span decades. Common issues that give rise to litigation include:

• Non-payment of rent or additional rent (operating costs, property taxes, insurance)
• Disputes over the landlord's right to terminate for breach
• Disagreements about the tenant's right to renew or extend the lease
• Disputes over permitted use, assignment, and subletting rights
• Landlord's failure to maintain or repair the premises
• Disputes over tenant improvement obligations and fit-out costs
• Exclusivity clause violations where a landlord permits a competing business in the same complex
• Disputes about what constitutes a default and whether proper notice was given

Ontario's Commercial Tenancies Act governs many aspects of commercial landlord and tenant relationships, but most rights and obligations are determined by the lease itself. The quality of the lease drafting and the specificity of its terms are often the most important factors in determining who prevails in a commercial tenancy dispute.

Construction disputes

Construction disputes arise at every stage of a commercial real estate development or renovation project. They are among the most technically complex real estate litigation matters, often involving multiple parties, expert evidence, and claims under Ontario's Construction Act.

Common causes of construction disputes include:

• Project delays that cause financial loss to the owner or other contractors
• Defective workmanship or materials that fail to meet the contract specifications
• Disputes over the scope of work and whether additional charges are properly owed
• Unpaid invoices and disputes about payment certification
• Termination of the construction contract by either party
• Mechanics lien claims by contractors, subcontractors, and suppliers

Ontario's Construction Act provides a specific and complex regime for construction disputes, including prompt payment obligations, adjudication, and mechanics lien rights. Strict deadlines apply to preserving lien rights, and missing them can be fatal to a claim. Anyone involved in a construction dispute in Ontario should obtain legal advice immediately to ensure their statutory rights are preserved.

Co-ownership and joint venture disputes

Commercial real estate is frequently owned jointly by investors, business partners, or development partners. When the relationship between co-owners breaks down, the property can become the subject of protracted and expensive litigation.

Common co-ownership disputes include disagreements about property management decisions, disputes over the distribution of rental income or development profits, deadlock between co-owners on whether to sell or develop the property, and allegations of breach of fiduciary duty or misappropriation of funds by one co-owner.

Where co-owners cannot agree on the future of the property, Ontario's Partition Act provides a remedy: any co-owner can apply to court for an order of partition or sale. Courts generally prefer sale over physical partition for commercial properties, and will grant an order for sale unless there are compelling reasons not to. This gives any co-owner a powerful exit mechanism, but it can also be used strategically by a co-owner who wants to force a sale at an inconvenient time for the other.

Purchase and sale disputes

Disputes arising from the purchase and sale of commercial real estate typically involve one party's failure or refusal to close the transaction, misrepresentation about the property's condition or income, disputes about whether conditions were properly waived or satisfied, and title defects discovered after closing.

Where a buyer or seller refuses to close a firm commercial real estate transaction, the innocent party's primary remedy is specific performance: a court order compelling the defaulting party to complete the transaction. Courts in Ontario regularly grant specific performance for commercial real estate transactions on the basis that every piece of real estate is unique and damages alone are not an adequate remedy. This is a more powerful remedy than is available in most other commercial disputes.

Landlord and tenant: rights and remedies in detail

Because lease disputes are so common, it is worth examining the specific remedies available to commercial landlords and tenants in Ontario in more detail.

Landlord remedies for tenant default: Under Ontario's Commercial Tenancies Act and at common law, a commercial landlord whose tenant is in default has several options. The landlord can distrain on the tenant's goods, meaning they can seize and sell the tenant's property on the premises to recover unpaid rent, subject to specific procedural requirements. The landlord can terminate the lease and recover possession. Where the tenant abandons the premises or the landlord terminates for cause, the landlord can claim damages representing the remaining rent owing under the lease term, subject to a duty to mitigate by re-letting the premises.

Tenant remedies for landlord default: A commercial tenant whose landlord fails to maintain the premises, interferes with the tenant's quiet enjoyment, or breaches other lease obligations has claims for damages, rent abatement, and in serious cases, the right to treat the lease as repudiated and vacate the premises. Tenants who face a landlord's wrongful termination attempt can seek injunctive relief to remain in possession while the dispute is resolved.

How to prevent commercial real estate disputes

The most effective approach to commercial real estate disputes is to prevent them from arising in the first place. Most commercial real estate litigation originates from one of three sources: ambiguous or inadequate contract drafting, failure to conduct proper due diligence before entering an agreement, and inadequate communication between the parties during the relationship.

Clear, detailed contracts

A commercial lease or purchase agreement that addresses every material contingency clearly is the most effective protection against future dispute. This means specifying each party's obligations in precise terms, addressing what happens when things go wrong (default provisions, notice requirements, cure periods), defining key terms that could otherwise be disputed, and including dispute resolution mechanisms that reflect the parties' preferences for how disagreements should be resolved.

Ambiguity in a commercial lease is almost always resolved through litigation at significant cost to both parties. The cost of having a litigation lawyer review a commercial lease before signing is a fraction of the cost of disputing an ambiguous term after a conflict arises.

Due diligence before committing

Proper due diligence before entering a commercial real estate transaction includes reviewing zoning laws and permitted use, conducting a title search and reviewing any encumbrances or restrictions on the property, reviewing existing leases if the property is income-producing, understanding environmental obligations and liabilities, and reviewing the financial position of the counterparty. Problems discovered through due diligence before signing can be addressed through negotiation. Problems discovered after closing typically become litigation.

Legal review before signing

Commercial real estate agreements are complex legal documents. Having a commercial litigation lawyer review the agreement before signing does not just identify legal risks: it creates an opportunity to negotiate better terms, ensure the agreement reflects the parties' actual intentions, and include dispute resolution mechanisms that will serve both parties well if the relationship breaks down. Many commercial real estate disputes could have been avoided if one or both parties had obtained proper legal advice before entering the agreement.

Alternative dispute resolution in commercial real estate

Not every commercial real estate dispute needs to go to court. Alternative dispute resolution (ADR) offers a faster, more private, and often less expensive path to resolution, and many commercial leases and construction contracts include mandatory ADR provisions.

Mediation

Mediation involves a neutral third party who facilitates negotiation between the disputing parties. The mediator does not impose a decision: their role is to help the parties reach a mutually acceptable resolution. Mediation is voluntary and confidential. It is particularly useful in commercial real estate disputes where the parties have an ongoing relationship (landlord and tenant, co-owners, developer and contractor) and want to preserve it, or where both parties want to avoid the cost and publicity of litigation.

In Ontario, mandatory mediation is required for most civil cases in Toronto, Ottawa, and Windsor before the matter can proceed to trial. For commercial real estate disputes in other jurisdictions, mediation can be agreed to voluntarily at any stage.

Arbitration

Arbitration is a more formal process in which a neutral arbitrator (or panel) hears evidence and arguments from both sides and issues a binding decision. Many commercial leases include mandatory arbitration clauses for specific types of disputes, such as rent review determinations or disagreements about the exercise of renewal options. Arbitration is private, typically faster than court proceedings, and the decision is generally final and binding with limited rights of appeal.

When litigation is necessary

In some commercial real estate disputes, litigation is the only appropriate response. Where urgent relief is needed, such as an injunction to prevent a landlord from wrongfully terminating a lease or to stop construction that is encroaching on your property, a court application is required. Where the other party is not acting in good faith and is unlikely to engage meaningfully in ADR, commencing court proceedings may be necessary to bring them to the table. Where the amounts involved are significant and the legal issues are complex, the discipline and procedures of litigation may produce a more reliable outcome than less formal processes.

Commercial real estate disputes in British Columbia

BC businesses face similar commercial real estate disputes to those in Ontario, but the legal framework differs in several important respects. Commercial tenancy in BC is governed by the Commercial Tenancy Act (RSBC 1996, c. 57) rather than Ontario's Commercial Tenancies Act. Construction disputes are governed by BC's Builders Lien Act rather than Ontario's Construction Act, with its own prompt payment and lien preservation rules. Co-ownership disputes and partition applications proceed under BC's Partition of Property Act.

The general principles of contract law, the availability of specific performance for real estate transactions, and the use of injunctive relief in urgent situations are consistent between Ontario and BC. However, the specific statutory provisions, deadlines, and procedural rules differ significantly. BC businesses involved in commercial real estate disputes should work with a lawyer familiar with BC commercial property law and BC Supreme Court procedure.
