Unlike residential tenancy, where a landlord is legally required to guarantee the "habitability" of a property, commercial landlords in Manitoba face no such universal mandate. In commercial real estate, maintenance responsibilities are primarily defined by the language constructed within the lease agreement. The primary governing statute for commercial tenancies in the province is The Landlord and Tenant Act (C.C.S.M. c. L70), which has been in force since 1 February 1988. Additionally, The Real Property Act (C.C.S.M. c. R30) implies certain maintenance covenants under Section 93, such as the tenant's obligation to keep the premises in "good and substantial repair" unless specifically excluded by the lease agreement.

"As-Is" Commercial Properties

A hallmark of commercial leasing in Manitoba is that the tenant typically accepts the premises in an "as-is, where-is" condition:

  • The tenant is responsible for conducting structural inspections prior to signing the lease
  • The tenant cannot hold the landlord responsible for issues discovered post-occupancy
  • Exceptions: The landlord may be liable if they fraudulently concealed a known defect or made specific representations about the property's condition in the lease

Pre-Lease Due Diligence

Prudent tenants should conduct (and landlords should expect):

  • Structural inspection — Foundation, roof, walls, and building envelope
  • Environmental assessment — Phase I ESA for contamination (especially for former industrial/gas station sites)
  • Building systems review — HVAC, electrical, plumbing, fire suppression
  • Code compliance review — Verify the space meets current building code for the intended use

Maintenance Allocation by Lease Type

The distribution of maintenance responsibilities varies dramatically based on the lease structure:

Lease TypeLandlord MaintainsTenant Maintains
Gross LeaseEverything (structure, systems, common areas)Interior cleanliness only
Modified GrossStructure + specified systemsInterior + specified systems
Single Net (N)Structure + insurance + maintenanceProperty taxes only
Double Net (NN)Structure and maintenanceTaxes + insurance
Triple Net (NNN)Structure only (sometimes)Everything else
Absolute NNNNothingEverything, including structure

The Triple Net (NNN) Lease Standard

The most prevalent lease structure in Manitoba commercial real estate — particularly for free-standing buildings, retail plazas, and industrial parks — is the Triple Net (NNN) lease.

What the Tenant Pays

In an absolute NNN lease, the tenant is financially responsible for virtually everything:

  • Net 1 (Taxes) — All property taxes and municipal assessments
  • Net 2 (Insurance) — Both the tenant's commercial liability and contributing to the building's property insurance
  • Net 3 (Maintenance) — Complete interior and exterior maintenance, including capital repairs

Common NNN Modifications

In practice, NNN leases are frequently modified. The most common arrangement:

ComponentTypical Allocation
FoundationLandlord
Load-bearing wallsLandlord
Roof membraneLandlord (or shared with tenant)
Exterior walls and claddingLandlord
Interior walls and finishesTenant
HVAC systemsTenant (maintenance); Landlord (replacement — negotiated)
Plumbing

| Tenant (interior); Landlord (building mains) | | Electrical | Tenant (interior); Landlord (building mains) | | Parking lot | Landlord or shared | | Landscaping | Landlord or shared | | Snow removal | Landlord or tenant (depending on property type) |

Special Focus: HVAC Obligations

Disputes over Heating, Ventilation, and Air Conditioning (HVAC) systems are notoriously common in commercial leasing, particularly in Manitoba where extreme temperature swings stress mechanical systems.

Maintenance vs. Replacement

ObligationTypically Assigned To
Quarterly preventative maintenance contractsTenant
Filter replacementTenant
Minor repairs (belt replacement, thermostat)Tenant
Major component repair (compressor, condenser)Negotiated — often tenant
Full unit replacementOften landlord, but heavily negotiated

HVAC Best Practices for Leases

  • Require the tenant to maintain a quarterly preventative maintenance contract with an approved HVAC service provider
  • Specify who pays for emergency after-hours service calls
  • Define the useful life threshold (e.g., landlord replaces units older than 15 years)
  • Include a cap on tenant liability for capital replacements (e.g., tenant pays first $5,000; landlord covers the remainder)
  • Require the tenant to provide copies of service reports to the landlord quarterly

Manitoba-Specific HVAC Considerations

Manitoba's extreme climate creates unique HVAC concerns:

  • Heating systems must be capable of operating in temperatures below -40°C
  • Backup heating provisions may be advisable for critical commercial operations
  • Air conditioning demand during summer heat waves can stress aging systems
  • Landlords should ensure HVAC systems are winterized before each heating season

Common Area Maintenance (CAM) Charges

In multi-tenant buildings (strip malls, office towers, shopping centres), the landlord performs exterior and common area maintenance and bills tenants for their proportionate share.

What CAM Typically Includes

CategoryExamples
Exterior maintenanceParking lot repairs, line painting, curb maintenance
LandscapingLawn care, tree trimming, flower beds
Snow removalParking lot and sidewalk clearing, salting
SecurityPatrol services, cameras, lighting
CleaningCommon area janitorial, waste removal
UtilitiesCommon area lighting, water for landscaping
Management feesProperty management company fees (typically 3–5% of gross rent)

CAM Reconciliation Process

  1. Monthly estimates — Tenants pay monthly prepayments based on the landlord's budget estimate
  2. Annual reconciliation — The landlord compiles actual costs at year-end
  3. Adjustment — If actual costs exceed estimates, tenants pay the shortfall; if under, tenants receive a credit
  4. Audit rights — Well-drafted leases grant tenants the right to audit the landlord's CAM records

Disputes Over CAM Charges

Common disputes include:

  • Capital expenditures disguised as CAM — Tenants may challenge charges for capital improvements (new roof, parking lot repaving) being passed through as operating expenses
  • Management fee markup — Tenants may dispute management fees that seem excessive
  • Vacant unit allocation — Whether the landlord absorbs CAM costs for vacant units or passes them to remaining tenants
  • Statutory Forfeiture — Under Section 19 of The Landlord and Tenant Act, a landlord may seek to forfeit the lease for breach of maintenance covenants, though courts frequently grant "relief against forfeiture" if the tenant remedies the breach.

Best Practices for Landlords

  1. Clearly define maintenance responsibilities in the lease — Ambiguity leads to disputes
  2. Require preventative maintenance contracts — For HVAC, fire suppression, and elevator systems
  3. Conduct regular building inspections — Proactive maintenance prevents costly emergency repairs
  4. Maintain transparent CAM records — Provide tenants with detailed annual reconciliation statements
  5. Budget conservatively for capital expenditures — Set aside reserves for roof replacement, parking lot repaving, and major system upgrades
  6. Specify HVAC replacement thresholds — Define who pays for replacement based on the system's age
  7. Include audit rights — Offering CAM audit rights builds tenant trust and reduces disputes
  8. Winterize annually — Given Manitoba's climate, proactive winterization of all building systems is non-negotiable
