Commercial and Residential Tenancy Review for Mixed-Use Buildings in Ontario

Residential tenancies are subject to Ontario’s residential tenancy legislation and related requirements. The written lease is important, but it does not necessarily contain every right or obligation applying to the tenancy.

This distinction affects:

• Rent
• Deposits
• Rent increases
• Lease renewals
• Maintenance obligations
• Utility responsibilities
• Assignment and subletting
• Termination
• Tenant notices
• Vacant possession
• Renovation plans
• Owner occupancy
• Available remedies

A seller, listing agent or buyer cannot treat the entire building as though every occupant is governed by one commercial lease.

Each commercial space, residential unit, parking arrangement and other occupied area should be documented and reviewed separately.

Start With an Occupancy Schedule

Prepare an occupancy schedule identifying every person or business using the property.

For each space, record:

• Unit or space identifier
• Location within the building
• Occupant’s legal name
• Type of occupancy
• Written or verbal agreement
• Lease commencement date
• Lease expiry date
• Renewal or extension rights
• Current rent
• Additional rent
• Included utilities
• Parking and storage
• Deposits held
• Arrears
• Required possession
• Known disputes
• Seller or related-party occupancy

The schedule should cover more than the obvious storefront and apartments.

Investigate basements, garages, rear buildings, parking spaces, storage areas, patios, signage locations, shared rooms and any space used by the seller or a related business.

An undocumented occupant or side arrangement can affect possession, income, insurance, renovation and closing.

Documents to Request

Request complete records rather than summaries prepared for marketing.

These may include:

• Current rent roll
• Commercial leases
• Commercial lease amendments
• Renewal and extension agreements
• Assignments
• Subleases
• Indemnities and guarantees
• Estoppel certificates
• Residential tenancy agreements
• Rent ledgers
• Rent-increase notices
• Deposit records
• Payment history
• Notices served or received
• Settlement agreements
• Tribunal or court documents
• Maintenance requests
• Repair records
• Utility arrangements
• Parking agreements
• Storage agreements
• Property-management records
• Tenant correspondence
• Evidence of arrears
• Details of concessions or free rent
• Information about disputes
• Seller representations concerning occupancy

Documents should be compared with the actual layout, physical occupancy and financial records.

A rent roll should not be accepted as proof that the leases are complete, the rent is lawful or the occupants will leave when requested.

Review the lease with qualified legal counsel before relying on its income or possession terms.

Important commercial lease issues include:

• Correct landlord and tenant names
• Legal status of the tenant
• Description of the leased premises
• Lease commencement and expiry
• Renewal or extension options
• Base rent
• Additional rent
• Rent escalations
• Security deposits
• Prepaid rent
• Guarantees and indemnities
• Permitted use
• Exclusivity rights
• Operating covenants
• Assignment and subletting
• Repair obligations
• HVAC responsibility
• Utility responsibility
• Insurance requirements
• Signage rights
• Parking and loading rights
• Access rights
• Maintenance obligations
• Default provisions
• Termination rights
• Demolition or redevelopment clauses
• Restoration obligations
• Rights of first refusal or first offer
• Registration on title
• Outstanding disputes

The financial value of the lease depends on more than the stated rent.

A strong rent figure may be undermined by unrecoverable expenses, weak security, extensive landlord obligations, tenant termination rights or an approaching lease expiry.

Confirm the Commercial Tenant and Premises

Confirm that the business occupying the property is the same legal entity named in the lease.

A trade name displayed on the storefront may not be the tenant that signed the agreement. The operating business may have been sold, assigned or reorganized without complete documentation.

Review:

• Corporate tenant name
• Business or trade name
• Assignment history
• Subtenants
• Franchise arrangements
• Guarantors
• Related companies
• Actual space occupied
• Shared or additional space used

Compare the lease plan with the building.

A tenant may use a basement, rear storage area, parking spaces, rooftop equipment or signage location that is not clearly addressed in the lease. These arrangements can affect renovation plans and the buyer’s intended use.

Base Rent and Additional Rent

Determine exactly what the tenant is required to pay.

Commercial income may include:

• Base rent
• Property-tax recovery
• Insurance recovery
• Common-area costs
• Utilities
• Maintenance charges
• Management or administration fees
• Percentage rent
• Parking income
• Signage income

A lease described as net does not automatically make every property expense recoverable.

Review the lease wording and compare recoverable amounts with actual billings and payments. Determine which expenses remain the owner’s responsibility.

Check for:

• Caps on recoveries
• Excluded expenses
• Fixed additional rent
• Gross-up provisions
• Audit rights
• Reconciliation requirements
• Delayed billings
• Uncollected recoveries
• Disputed charges

Reported commercial revenue should be separated into contractual rent, expense recovery and other income.

Review:

• Current expiry date
• Renewal options
• Notice requirements
• Renewal rent formula
• Conditions attached to renewal
• Tenant termination rights
• Landlord termination rights
• Demolition clauses
• Relocation rights
• Early-access arrangements
• Overholding provisions

An expiry date does not always mean the buyer will receive possession on that date. Renewal rights, overholding, amendments, waivers or disputes may affect the outcome.

If the buyer needs the commercial space for its own business, legal counsel should confirm whether and when possession can be delivered.

Repair, Maintenance and Capital Obligations

Determine which party is responsible for the building and its systems.

Review responsibility for:

• Roof
• Structure
• Exterior walls
• Storefront
• Windows and doors
• HVAC
• Plumbing
• Electrical service
• Fire systems
• Sprinklers
• Commercial kitchen equipment
• Grease interceptors
• Exhaust and ventilation
• Snow removal
• Landscaping
• Waste removal
• Parking areas
• Signs
• Environmental conditions
• Accessibility work
• End-of-term restoration

A tenant may maintain its equipment while the owner remains responsible for replacement. A landlord may also retain responsibility for major capital work even under a net lease.

These obligations should be included in the property’s operating and capital budget.

Commercial Tenant Financial Strength

A lease is only as dependable as the tenant’s ability and willingness to perform.

Investigate:

• Payment history
• Arrears
• Returned payments
• Financial information where available
• Length of operation
• Business condition
• Corporate status
• Guarantees
• Security deposits
• Disputes
• Requests for concessions
• Temporary rent arrangements
• Dependency on the current owner
• Franchise or licence status

A high contractual rent does not create reliable income when the tenant is financially weak or already in default.

Related-party and seller-operated leases require particular scrutiny. Their terms may not reflect market conditions, and the tenant may not remain after closing.

The available process depends on the type of occupancy, documents, intended use and applicable law.

Do not assume that purchasing the property creates an unrestricted right to remove an occupant.

Before making an offer firm, obtain legal advice concerning:

• Who intends to occupy
• Which space is required
• Whether the proposed reason is legally available
• Required evidence
• Required notices
• Timing
• Compensation or other obligations
• Existing lease terms
• Closing conditions
• Risk of delay or dispute

The buyer should also confirm that zoning, building condition and permits allow the intended use once possession is obtained.

Sale of the Property Does Not End the Tenancies

The transfer of ownership does not automatically eliminate existing commercial leases or residential tenancies.

The buyer may acquire the property subject to existing occupancy arrangements.

Closing documentation may need to address:

• Assignment of commercial leases
• Assumption of landlord obligations
• Transfer of deposits
• Prepaid rent
• Rent adjustments
• Outstanding reconciliations
• Tenant notices
• Existing claims
• Security interests
• Guarantees
• Keys and access devices
• Tenant records
• Property-management transition

The buyer’s lawyer should determine which obligations transfer and what representations, deliveries and adjustments are required at closing.

Tenancies and Property Financing

Lenders may review commercial and residential income differently.

They may request:

• Commercial leases
• Residential rent roll
• Rent ledgers
• Tenant payment history
• Operating statements
• Estoppel certificates
• Vacancy information
• Lease-expiry schedule
• Renewal options
• Tenant financial information
• Details of arrears
• Evidence of lawful units
• Environmental reports
• Appraisal

Income may be discounted when leases are incomplete, tenants are related to the seller, rent is not being collected, units are not verified or possession is uncertain.

A financing condition should provide enough time for the lender to review the property’s tenancy documents—not merely the borrower’s financial position.

• Tenant termination rights
• Unrecoverable expenses
• Significant landlord repair obligations
• Arrears
• Informal agreements
• Uncertain vacant possession
• Related-party leases
• Unlawful residential units

Renovating an Occupied Mixed-Use Building

Renovation can affect commercial and residential occupants differently.

Before planning work, investigate:

• Landlord access rights
• Required notices
• Tenant safety
• Fire exits
• Noise and dust
• Utility interruptions
• Washroom access
• HVAC shutdowns
• Business interruption
• Residential habitability
• Temporary protection
• Insurance
• Contractor access
• Lease obligations
• Required permits
• Construction schedule

A contractor’s preferred schedule does not override lease terms or applicable tenancy requirements.

Renovation assumptions should be reviewed with the buyer’s lawyer, insurer, consultants and contractors before the purchase becomes unconditional.

Tenancy Due-Diligence Red Flags

Investigate further when you find:

• Missing leases or tenancy agreements
• Rent that does not match payment records
• Undocumented occupants
• Commercial assignments without landlord documentation
• Expired commercial leases with unclear overholding terms
• Unverified renewal options
• Residential increases without supporting records
• Deposits that cannot be reconciled
• Arrears excluded from the marketing package
• Side agreements disclosed late
• Seller-operated or related-party leases
• Tenant complaints concerning major repairs
• Vacant possession promised without legal support
• Existing notices treated as guaranteed outcomes
• Units not supported by municipal records
• Commercial tenants using more space than the lease describes
• Unrecorded parking, storage or signage rights
• Tenant improvement or repair commitments not shown in the operating statement

A red flag does not necessarily make the property unsuitable.

It means the issue should be documented, legally reviewed, financially measured and addressed before the buyer waives conditions.

Before committing to a tenanted mixed-use property, verify:

• Every occupied space
• Correct tenant and occupant names
• Complete commercial lease documents
• Complete residential tenancy records
• Current contractual rent
• Current lawful residential rent
• Actual payment history
• Additional-rent recoveries
• Deposits and prepaid rent
• Renewal and termination rights
• Repair and maintenance obligations
• Utility responsibilities
• Parking, storage and signage rights
• Arrears and disputes
• Side agreements
• Estoppel requirements
• Required vacant possession
• Closing assignments and adjustments
• Renovation effects on occupants
• Legal status of residential units

Five Mixed-Use Tenancy Facts

• Commercial leases and residential tenancies require separate document, financial and legal reviews.
• The expiry of a residential fixed term does not automatically guarantee vacant possession.
• A commercial lease described as net may still leave substantial expenses and capital obligations with the owner.
• Projected market rent should not be treated as current income when an existing residential tenancy limits what can presently be collected.
• A sale of the property does not automatically end the building’s existing tenancies.

Brokerage and Construction Experience

OntarioCRE combines commercial brokerage with practical construction and renovation experience to help buyers assess tenancy, occupancy and project risk before committing.

This can include preliminary review of:

• Commercial and residential configuration
• Rent rolls and occupancy schedules
• Required vacant possession
• Commercial build-out requirements
• Residential renovation plans
• Tenant access and interruption concerns
• Utility arrangements
• Building-condition issues
• Construction staging
• Total acquisition and renovation cost

This review does not replace legal advice, tenancy advice, lender review, municipal confirmation, accounting, appraisal or professional building investigations.

It helps buyers identify which tenancy issues require further investigation and whether the property can support the intended business, investment or renovation strategy.
