Leasing commercial space is the largest fixed cost most businesses take on, and the lease you sign will govern your operations for the next five to ten years. Deep Singh represents business tenants across Kitchener, Waterloo, Cambridge, Guelph, and the GTA — finding the right space, then negotiating the terms that sit underneath the headline rent.
Two spaces advertised at the same rent per square foot can cost wildly different amounts once you account for lease structure. This is the single most common place where first-time commercial tenants get caught out.
| Lease Type | Tenant Pays | Common For |
|---|---|---|
| Triple Net (NNN) | Base rent plus property taxes, building insurance, and common area maintenance | Retail plazas, industrial, standalone buildings |
| Modified Gross | Base rent plus some operating costs — split is negotiated deal by deal | Office, mixed-use buildings |
| Full-Service Gross | One all-in rent — landlord covers taxes, insurance, maintenance, often utilities | Multi-tenant office buildings |
A 2,000 sq ft retail unit at $18/sq ft NNN with additional rent of $9/sq ft costs $54,000 per year, not $36,000. The same unit quoted at $26/sq ft full-service gross costs $52,000 — cheaper, despite the higher advertised rate. Always ask for the additional rent figure before comparing anything.
Rent is the number everyone focuses on. It’s rarely where the most value sits.
Budget three to six months from starting the search to taking possession — longer if you need significant build-out or a zoning change. Starting early is the cheapest negotiating advantage there is.
Most Waterloo Region landlords will agree to around two months of free rent without much argument — it is close to standard, and tenants who stop there often think they have negotiated well. The real gains I have won for clients came from the two things landlords resist harder: improvement allowance and base rate. Landlords protect the headline rate because it is what their lender and any future buyer sees, which is precisely why pushing there is worth the effort. Ask for the free rent, then keep going.
A triple net lease means the tenant pays base rent plus their proportionate share of three additional costs: property taxes, building insurance, and common area maintenance. These extras are called additional rent or TMI, and in Waterloo Region they commonly run $6 to $14 per square foot on top of base rent. Always ask for the current additional rent figure and the last two years of history before signing.
A modified gross lease sits between triple net and full-service gross. The tenant pays base rent plus some — but not all — operating costs, with the split negotiated in each deal. A common structure has the landlord covering taxes and insurance while the tenant covers utilities and in-suite maintenance. Because there’s no standard definition, the specific split must be spelled out in the lease.
A full-service gross lease bundles everything into one rent figure. The landlord pays property taxes, insurance, maintenance, and usually utilities and janitorial out of the rent you pay. It’s most common in multi-tenant office buildings. The advantage is budget certainty; the trade-off is that landlords price in a risk buffer, and many such leases still allow costs above a base year to be passed through.
Five years is the most common term, with a five-year renewal option. Smaller retail and office units are sometimes available on three-year terms. Industrial and larger retail deals often run five to ten years. Longer terms give you more leverage on free rent and tenant improvement allowance, because the landlord is amortizing those costs over more years.
Yes. Commercial leases in Ontario carry none of the tenant protections that residential tenancies do — the Residential Tenancies Act does not apply, and the document you sign governs almost entirely. A commercial lease review typically costs a fraction of one month’s rent and routinely catches restoration obligations, guarantee terms, and demolition clauses that would cost far more later.
Leasing preserves capital and flexibility, which matters most if your space needs are likely to change within five years. Buying builds equity, fixes your occupancy cost, and can be financed with as little as 10% to 20% down for owner-occupied premises under the Canada Small Business Financing Program. As a rough guide, if you’re confident about your space needs for ten-plus years and have the down payment available, buying usually wins on total cost. See buying commercial property for the full comparison.
