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.

National average resale-price growth and housing-starts growth, smoothed over three months. The comparison illustrates the cycle; it does not establish how much a price change causes construction to change.
Trailing 12-month starts in centres of 50,000 or more remove the usual monthly seasonality. Ownership combines the homeowner and condominium categories; rental is shown separately.
Six-month averages of provincial starts, expressed at annual rates. The smoothing reduces the influence of individual apartment projects.
The same August benchmark compared with two different starting points. Three-month changes are not annualized.
Average sale prices show the difference in purchase costs across markets. They do not measure affordability relative to local incomes or construction costs.
Newfoundland and Labrador remains above its pre-pandemic sales pattern, but August activity was below last year. Historical lines retain their original release vintages.
Average and median describe different aspects of the same month’s transactions. Both are affected by the mix of homes sold.
Category averages compare different homes and locations; the gaps are not estimates of the cost to upgrade an otherwise identical property.
The five categories shown account for 5,000 of the board’s 5,057 sales. The remaining 57 transactions were in other housing categories.
Monthly observations are not seasonally adjusted. Active listings count properties available at month-end; they are not construction inventory.
Average and median prices share one dollar axis. These unadjusted transaction measures do not control for changes in the homes sold.
TRREB’s 416/905 categories compare the apartments sold in each area. The difference does not isolate a location premium for equivalent units.
