Small Warehouse for Rent in Ontario: How Industrial Leases Are Priced, What the Smallest Units Look Like, and the Yard-of-Your-Own Alternative

Reading Time: 12 minutes

How an Ontario industrial lease is actually priced

An industrial lease in Ontario is quoted the way nobody outside the trade expects: as net rent, a number per square foot per year, that is not the rent. We sell steel boxes from a yard in Brantford and do not lease anything, so this page is the tenant’s briefing written by the other side of the fence. The tenant pays that number divided by twelve each month, plus additional rent, which is the landlord’s property taxes, building maintenance and insurance passed through per square foot, plus utilities, usually separately metered, plus HST on all of it. A listing that reads as one figure is the net figure; the cheque is the net figure plus the additional rent plus the hydro plus the tax, and on a small bay the additional rent can be a fifth to a third again on top of the net. That structure is why two units that look the same on a portal cost different money, and why the first question to ask a leasing agent is not the rate but what the rate includes. It is also the first thing a business owner should understand before deciding whether a warehouse is the answer at all, because the container against warehouse storage is a comparison that only works once the warehouse side is priced correctly. The numbers here are left as structure rather than dollars, because rates move by the quarter and by the block.

Additional rent: the TMI line and what it hides

Additional rent is the line tenants underestimate, and the leasing trade calls it TMI: taxes, maintenance and insurance. It is quoted as an estimate per square foot per year at signing, billed monthly, and reconciled at year end against what the landlord actually spent, so a tenant who budgeted the estimate gets a catch-up invoice the following spring if the property taxes rose or the roof was repaired. Maintenance in a multi-tenant plaza means the common areas, the parking lot, the snow, the landscaping and the management fee, and in a small bay the tenant’s share is proportional to floor area, so the smallest unit pays the same rate as the largest. The Q2 2026 GTA West market read puts additional rent as a separate weighted figure by submarket, with Mississauga the highest, which tells a small tenant two things: the line is real money, and it varies enough by municipality that the same net rent in two towns is not the same cheque. What TMI does not cover is the inside of the unit: the tenant’s own insurance, the hydro, the gas, the alarm, the racking, and the repairs to anything the tenant touches. Insuring a container on your own lot is the equivalent line on the other side of the comparison, and it is one line rather than four.

Term, escalations, deposits and the personal guarantee

A small industrial lease in Ontario is not a month-to-month arrangement. The GTA West read shows mid-market deals at 48 to 121 months and large-format commitments at 84 to 180, and a small bay in a plaza typically signs for three to five years with a renewal option, annual escalations written in, a deposit of first and last, and, for a young company, a personal guarantee from the owner, which means the lease survives the business if the business does not. The inducements the market offers in 2026 are worth reading carefully: the same read found six months of free rent on a 121-month term in Halton Hills and a seven-month fixturing period in Caledon, with the Oakville small-bay flex units asking the region’s top rates, and those inducements are real value but are paid for by the length of the commitment. A tenant who needs space for two seasons is signing for five years to get it, and the exit is a sublease or an assignment that needs the landlord’s consent and clears, in the current market, materially below the direct rate. A box bought outright has no term at all, and how long a container actually lasts is the only calendar on the other side of that comparison.

What the smallest units look like

The smallest industrial bay a tenant can lease in most Ontario plazas is around a thousand square feet, and fifteen hundred to twenty-five hundred is the common floor, because landlords do not demise smaller than the plumbing and the doors allow. A small bay is a rectangle with a drive-in door at grade, sometimes a dock, a man door, a small washroom, a mezzanine or an office box in one corner, a clear height of sixteen to twenty-two feet in the older plazas that hold most of the small units, three-phase power in some and single-phase in more than tenants expect, and a shared yard where the truck backs in. Zoning is municipal and a warehouse use in an industrial zone is straightforward, while a retail counter or a wash bay in the same unit is a conversation with the city. The bay is heated to keep the sprinklers from freezing, which is not the same as heated for a person, and the tenant fits out the rest: racking, lighting, the alarm, the second washroom. For the tenant whose stock is three pallets and a van’s worth of tools, the smallest bay is three times the room and four times the cheque, and the stock room built in a box is what that tenant usually ends up with instead.

The 2026 market: availability, subleases and inducements

The small tenant is shopping into a market that loosened after the 2022 peak and is tightening again. The Q2 2026 GTA West read has overall availability at 5.3 percent, lease availability at 4.0 percent, and a sublease pool of about one percent of inventory, the largest shadow supply in the region, concentrated in Bolton and Caledon at 1.6 percent and Brampton at 1.4 percent. Two things follow for a small tenant. First, the sublease market is where the value is, because sublease space clears materially below direct-lease benchmarks, and a tenant who can live with someone else’s remaining term and someone else’s fit-out gets the best rate in the market. Second, small-bay product under 25,000 square feet commands a premium in every submarket, because the demand for small units is deep and the supply is old, so the thousand-foot tenant is competing for the scarcest product with the least bargaining power. Landlords are responding with free rent and fixturing periods rather than lower headline rates, which flatters the effective rent on a long term and does nothing for a short one. The Mississauga overflow pattern is what the tenants who already have a bay do when it fills: a box in the yard rather than a second unit at the small-bay premium.

Who rents small warehouse space, and what they actually store

The small-bay tenant is rarely a warehouse business. It is the online seller who outgrew the spare room and holds forty pallets of inventory and a packing table; the contractor whose vans need a base, a parts wall and a place the trailer sleeps; the landscaper with mowers in winter and pallets of salt; the caterer with racks of rentals; the moving company with client goods; the retailer whose back room stopped being big enough. Each of them rents a thousand feet to use three hundred well and seven hundred as an aisle, and each of them is paying net rent, additional rent and hydro on the aisle. The honest sort is by what the space has to do beyond hold things: a business that needs a counter, a washroom, staff at a bench all day, a dock for a fifty-three-foot trailer or three-phase power needs a unit, and the lease is the price of those. A business that needs dry, locked, dense storage it visits daily needs a room, and a room is bought once. The HVAC and plumbing contractor’s parts store and the landscaper’s winter vault for mowers are two of those rooms built out by trade, and the trade setups hub has the rest.

The yard-of-your-own alternative, honestly

The alternative to the smallest bay is a yard the business already controls, the driveway of a home-based operation, the corner of a commercial lot the business owns or already leases for its counter, or the farm, with a steel box on it. A 20-foot container is 160 square feet, a 40-foot high cube is 320, and two or three of them racked properly hold more pallets than the thousand-foot bay’s usable floor, because a box is all floor and no aisle until the tenant chooses to leave one. It is bought outright, delivered in one to three days from our Brantford yards, sits on four blocks and a stone pad, locks behind cam doors and a shrouded padlock, and sells or moves when the business changes. What it is not is a unit: there is no washroom, no counter, no dock, no three-phase, no heat unless it is lined and wired, and a box on a lot the business rents for its storefront needs the landlord’s yes and the municipality’s, which is one conversation rather than a lease. The container against warehouse leasing is that comparison scored line by line, and the grade that suits a storage yard is wind-and-watertight for most of it. What moves the number is size, grade and distance, and the drivers behind a yard-box quote are the same list on every call. We sell outright, never rent; a business spreading the cost does it through its own bank with the invoice and the serial number we supply, and the box is an asset on the balance sheet rather than a line on the lease.

The math on one page

Here is the arithmetic without the dollars, because the structure is what decides it. The bay costs net rent times square feet, plus additional rent times the same square feet, plus hydro and tax, every month for the term, plus the deposit and the fit-out up front, plus whatever the guarantee costs if the business stumbles; divide the total by the months and by the square feet actually used and the true rate per useful foot is often double the headline. The box costs one number up front plus the pad and the lock, and then nothing monthly; divide by the months the business will use it, which for a bought box is as many as the business lasts, and the rate per useful foot falls every month it stays. The crossover is early, usually inside the first year of a small lease, and the box keeps a resale value the lease never has. The cases where the bay still wins are real and short: staff at a bench all day, a customer counter, a dock, three-phase, a use the yard cannot take, or a business with no yard at all. The self-storage locker against a box is the same sum at the small end, where the monthly meter is a locker rather than a lease, and buying the box cash or through the bank is the last line on the yard side.

The small-warehouse checklist

A business that runs that list ends up in the right place, and the right place is a unit more often than a container yard likes to admit and a box more often than a leasing agent does. The tenant who signs for five years to store three hundred feet of stock is the one this page was written for, and the container against every building and lease it competes with is the wider table when the choice is broader than bay or box.
