What Is an Offer to Lease in Ontario? Should You Have a Lawyer Review It Before Signing?

Finding the right commercial space is an exciting milestone for any business. Once you have identified a suitable location, the landlord may present you with an Offer to Lease rather than a full commercial lease agreement.

Many business owners assume this document is simply an expression of interest or a non-binding outline that will later be replaced by the formal lease. As a result, they often sign it without obtaining legal advice.

This can be a costly mistake.

An Offer to Lease frequently contains the key commercial terms that will form the basis of the final lease agreement. Once these terms are agreed upon, it may become significantly more difficult to negotiate changes later in the process.

Understanding what an Offer to Lease is and having it reviewed before signing can help protect your business and strengthen your negotiating position.

What Is an Offer to Lease?

An Offer to Lease is a document that outlines the principal business terms that the landlord and tenant intend to include in the formal commercial lease.

Although every document is different, an Offer to Lease commonly addresses:

• The premises being leased

• The lease term

• Renewal options

• Base rent

• Additional rent

• Tenant improvement allowances

• Rent-free periods

• Possession dates

• Permitted use of the premises

• Conditions that must be satisfied before the lease proceeds

Once accepted, the parties typically instruct lawyers to prepare the formal lease based on these agreed terms.

Is an Offer to Lease Legally Binding?

This is one of the most common questions business owners ask.

The answer depends on the wording of the document and the intentions of the parties.

Some Offers to Lease are expressly intended to be legally binding, while others state that they are subject to the execution of a formal lease agreement.

However, even where certain provisions are intended to be non-binding, other clauses may still create enforceable obligations.

For this reason, it is important not to assume that an Offer to Lease has no legal effect simply because it is not the final lease.

Why Reviewing the Offer Is So Important

Many business owners wait until the formal lease arrives before contacting a lawyer.

Unfortunately, by that stage, many of the key commercial terms have already been negotiated and accepted.

A lawyer reviewing the Offer to Lease can often identify issues before they become much more difficult to change.

Early legal review also allows your lawyer to recommend revisions while negotiations are still flexible.

Important Terms to Review Before Signing

Although every transaction is unique, an Offer to Lease should be carefully reviewed to ensure the proposed terms accurately reflect your business needs.

Particular attention should be given to:

• Lease length

• Renewal options

• Base rent

• Rent escalation provisions

• Additional rent obligations

• Tenant improvement allowances

• Repair responsibilities

• Personal guarantees

• Exclusivity rights

• Permitted use clauses

• Assignment and subleasing rights

• Conditions that must be be satisfied before occupancy

These provisions can significantly affect your business long after you move into the premises.

The Formal Lease Usually Expands on the Offer

The commercial lease itself is often much longer than the Offer to Lease.

While the Offer establishes the key business terms, the formal lease usually introduces additional legal provisions dealing with:

• Default

• Insurance

• Indemnities

• Maintenance

• Repairs

• Operating costs

• Environmental obligations

• Landlord remedies

• Tenant obligations

Because the lease expands upon the Offer, both documents deserve careful legal review.

Common Mistakes Business Owners Make

Business owners frequently:

• Sign the Offer to Lease without reading it carefully

• Assume the lawyer only needs to review the final lease

• Believe the Offer cannot be negotiated

• Focus exclusively on rent while overlooking other obligations

• Accept broad personal guarantees without discussion

These mistakes can reduce negotiating leverage and create unnecessary risk.

Why Having a Lawyer Review the Offer Can Save Time and Money

Reviewing an Offer to Lease before signing is often more efficient than attempting to renegotiate the final lease.

Identifying issues early may allow:

• Better commercial terms

• Clearer renewal rights

• More balanced repair obligations

• Reduced personal liability

• Improved flexibility for future business growth

Addressing these issues early often leads to smoother lease negotiations.

The Best Time to Obtain Legal Advice Is Before You Sign

One of the greatest advantages of early legal review is preserving your negotiating leverage.

Before the Offer to Lease is signed, both parties are still discussing the commercial relationship.

Once the key business terms have been accepted, landlords are often less willing to revisit them during preparation of the formal lease.

Obtaining legal advice early helps ensure your interests are protected before important decisions become more difficult to change.
