Many commercial tenants in Ontario are presented with documents prepared using forms published by the Ontario Real Estate Association (OREA). Because these forms are widely used by real estate agents and brokers, business owners often assume they are balanced agreements that protect both landlords and tenants.
In practice, however, OREA forms are frequently used as a starting point for commercial leasing transactions and may not address many of the legal and operational risks that affect business tenants.
Before signing an OREA commercial lease or agreement to lease, business owners should carefully review the document and understand the potential issues that may arise if important provisions are not negotiated or clarified.

What Is the OREA Commercial Lease Form?
The OREA Agreement to Lease Commercial is a standardized document commonly used in commercial real estate transactions across Ontario.
The form typically outlines basic business terms including:
• the lease term
• the base rent
• renewal provisions
• certain general responsibilities of the landlord and tenant
In many transactions the OREA document functions primarily as a framework for negotiating the final lease agreement rather than a comprehensive lease itself.
Because the form is designed to be broadly applicable to many types of properties, it may not address all issues that are important to a particular business.
For this reason, additional provisions are often negotiated and incorporated into the final lease documentation.
Standardized Forms May Not Address the Needs of Your Business
The OREA commercial lease form is intended to be used across a wide range of commercial leasing situations.
However, different businesses often require very specific provisions depending on the nature of their operations.
For example, a restaurant, medical clinic, retail store, or professional office may require detailed provisions addressing matters such as:
• permitted use of the premises
• renovation or improvement rights
• signage and exterior modifications
• regulatory or licensing requirements
If these issues are not clearly addressed in the lease documentation, disputes may arise regarding what activities the tenant is permitted to carry out within the premises.
Business owners should ensure the lease accurately reflects the operational needs of their business.
Maintenance and Repair Obligations May Be Unclear
Commercial leases typically allocate responsibility for maintenance and repairs between the landlord and the tenant.
In some cases tenants assume that certain building systems such as HVAC equipment or structural elements of the building will be maintained by the landlord.
However the wording of the lease may place responsibility for some of these costs on the tenant.
If these obligations are not clearly defined the tenant may face unexpected expenses during the lease term.
Reviewing the maintenance and repair provisions carefully can help ensure that responsibility for building systems, structural elements, and interior maintenance is properly allocated.
Additional Rent and Operating Costs May Be Significant
Many commercial tenants initially focus on the base rent stated in the lease agreement. However commercial leases frequently require tenants to pay additional rent representing their share of building operating costs.
These costs may include:
• property taxes
• building insurance
• maintenance of common areas
• building operating expenses
Depending on the terms of the lease these costs may fluctuate over time and can significantly affect the total cost of occupying the premises.
Tenants should review how these expenses are calculated and whether the lease provides transparency regarding the operating costs charged to tenants.
The Lease May Provide Limited Protection if the Property Is Sold
Commercial properties may change ownership during the term of a lease.
If the property is sold the new owner will generally assume the landlord’s rights and obligations under the lease. However the tenant’s protection ultimately depends on the wording of the lease agreement.
Business owners should ensure the lease clearly addresses the tenant’s right to remain in the premises if ownership of the building changes during the lease term.
Understanding how the lease will operate in the event of a sale of the property can help provide greater security for the tenant’s business operations.
Limited Flexibility if the Business Needs Change
Commercial leases often run for several years. During that time the needs of a business may change.
A business may wish to relocate, sell the business, or restructure its operations.
However many leases contain restrictions on assignment of the lease or subletting of the premises.
If these provisions are too restrictive the tenant may have limited flexibility to adapt to changes in the business.
Carefully reviewing these provisions before signing the lease can help ensure the tenant has reasonable flexibility if business circumstances change.
Why Legal Review of a Commercial Lease Matters
Commercial leases are detailed legal agreements that allocate financial and operational risks between landlords and tenants.
Before signing an agreement to lease or final lease documentation, business owners may wish to obtain legal advice to ensure they understand:
• the financial obligations created by the lease
• the allocation of maintenance and repair responsibilities
• restrictions affecting assignment or subletting
• renewal and termination provisions
Carefully reviewing these terms can help ensure that the lease supports the long term needs of the business.
