Commercial real estate in Markham is concentrated in three corridors: the Highway 7 office cluster anchored by IBM Canada, the Allstate Parkway employment district, and the industrial spine running east of Woodbine Avenue. Lease activity in the city tracked above 2.4 million square feet of new and renewed space in 2024, according to industry brokerage reports.
The leases driving that volume are not negotiated documents. They are landlord templates, drafted by counsel for institutional ownership groups, and presented to incoming tenants as final. Most tenants sign without striking a word. The cost of that decision compounds over the term.
The Net Lease Math Tenants Underestimate
Nearly all commercial space in Markham is leased on a triple-net basis. The tenant pays base rent plus a proportionate share of property taxes, building insurance and operating costs — known as additional rent or TMI. Operating costs cover maintenance, utilities for common areas, property management fees, snow removal, landscaping and structural reserves.
The standard form gives the landlord wide discretion over what counts as an operating cost. Capital expenditures, executive compensation, marketing for vacant space and the landlord’s own legal fees often appear in TMI reconciliations. A commercial real estate lawyer reviewing the lease before signing negotiates exclusions: capital costs amortized over useful life, caps on annual TMI increases, audit rights and a definition of base year that cannot be reset on assignment.
Demolition and Relocation Clauses
Several Markham office leases contain demolition clauses. The landlord retains the right to terminate the lease on six to twelve months’ notice if the building is to be redeveloped. For a tenant who has invested $200 per square foot in leasehold improvements, the clause converts those improvements into stranded capital.
Relocation clauses operate similarly. The landlord may require the tenant to move within the building or to another property. Both clauses are negotiable. Tenants with leverage — credit-rated covenants, strong rent roll history, willingness to walk — frequently strike them or limit their reach.
Personal Guarantees and Indemnities
Landlords routinely require personal guarantees from the tenant’s principals. The guarantee typically covers the full term plus any renewal, regardless of whether the corporate tenant later assigns the lease. A guarantee survives bankruptcy of the corporate tenant, sale of the business and resignation of the guarantor as a director.
A commercial real estate lawyer in Markham often negotiates a limited guarantee: capped to a fixed dollar amount, restricted to the first 24 to 36 months of the term, and released on hitting a performance threshold. Where the landlord refuses, the lawyer documents the exposure so the principal understands what has been signed.
Use Clauses, Exclusivity and Co-Tenancy
Retail tenants in Markham’s mixed-use developments require careful attention to use clauses. The clause defines the permitted business operation and the conditions for change. A narrow use clause prevents the tenant from pivoting the business model. A broad use clause without exclusivity allows the landlord to lease an adjacent unit to a direct competitor.
Anchor tenants in retail centres negotiate co-tenancy provisions. If an identified anchor leaves the centre, the tenant gains rent reduction rights or termination rights. The provisions are technical and rarely volunteered by the landlord. They require a tenant-side lawyer to insert.
Renewal Rights, Rent Reset and Estoppel
Most Markham commercial leases offer one renewal option of five years, with rent reset to fair market value as determined by appraisal. The standard form gives the landlord control of the appraisal process. A negotiated renewal provision specifies the appraisal mechanism, caps the rent increase to a percentage above the prior term, and requires the renewal to be exercised on a defined timeline.
Tenants assigning or subletting also encounter estoppel certificates — a document the landlord requires from the tenant confirming the lease terms for the benefit of a lender or purchaser. Inaccurate estoppel certificates create personal liability for the signing officer.

A lease is a 12-year obligation drafted by the landlord and presented as standard. It is not standard. Tenants who engage a commercial real estate lawyer in Markham before signing convert a one-sided document into a balanced one. Tenants who sign first usually discover the provisions only at renewal, dispute or exit.
