What is a Commercial Lease?

A commercial lease is a legally binding agreement between a landlord and a tenant for the rental of property used for business purposes, such as offices, retail, or industrial spaces.

Why Commercial Leases Matter in Real Estate

In Canadian real estate, commercial leases differ significantly from residential leases in terms of negotiation, customization, and legal complexity.



Common commercial lease types:
  • Gross lease: landlord pays most expenses
  • Net lease: tenant pays base rent plus some expenses
  • Triple net lease (NNN): tenant pays all operating costs



Commercial leases often involve longer terms, tenant improvements, and clauses for renewal, assignment, and termination.



Understanding commercial leases is critical for business owners, landlords, and investors managing risk, obligations, and occupancy rights.

Example of a Commercial Lease in Action

The business signs a five-year commercial lease with renewal options and tenant improvement allowances for their downtown retail store.

Key Takeaways
