A demolition clause gives the landlord the right to terminate your commercial lease early if they decide to demolish or substantially redevelop the building. In Ontario's rapidly developing urban centres, these clauses have become increasingly common — and increasingly dangerous for tenants who invest significant capital in leasehold improvements, build location-dependent customer bases, or operate businesses that can't easily relocate. The worst demolition clauses give landlords near-absolute discretion to terminate with minimal notice and no compensation. Better ones require substantial notice periods, relocation assistance, and compensation for unamortised improvements. Knowing what to look for — and what to negotiate — can mean the difference between an orderly transition and a business-ending disruption.
What is a Demolition Clause?
A demolition clause (sometimes called a redevelopment clause or demolition rider) is a provision in a commercial lease that permits the landlord to terminate the lease before its expiry date if the landlord intends to demolish the building or undertake substantial renovations that require vacant possession. The clause typically specifies the notice period, any compensation or relocation rights, and the conditions under which the landlord can invoke it.
Red flags to watch for
Relocating a commercial business takes significant time — finding new premises, negotiating a lease, fitting out, notifying customers. Anything less than 12 months' notice is commercially unreasonable for most businesses.
If you've invested $200,000 in fitting out your space and the landlord demolishes after 2 years of a 10-year lease, you should be compensated for the remaining value of those improvements.
Some clauses define demolition so broadly that replacing the HVAC system or updating the facade qualifies, giving the landlord a hair-trigger termination right for routine maintenance.
A landlord should only be able to invoke a demolition clause when they have genuine, approved plans. Without this requirement, the clause becomes a no-fault termination right they can exercise at will.
A blanket waiver means you can't claim for business disruption, moving costs, or lost goodwill even if the landlord terminates with inadequate notice.
Your legal rights
Ontario commercial lease tenants have limited statutory protection against demolition clauses. The Commercial Tenancies Act (Ontario) governs commercial lease relationships but does not specifically regulate demolition clauses, leaving them primarily to contract negotiation. However, the common law duty of good faith in contractual performance (Bhasin v Hrynew, 2014 SCC 71) requires landlords to exercise demolition rights honestly and not for an improper purpose. Municipal planning approvals under the Planning Act (Ontario) and building permits under the Ontario Building Code Act, 1992 are required before demolition can proceed, giving tenants some procedural protection. If the property is designated under the Ontario Heritage Act, additional restrictions on demolition apply. Tenants may also have rights under the Expropriations Act (Ontario) if the demolition is connected to a government taking.
