A warehouse can look operationally perfect during a tour and still create an expensive problem once the lease is signed. An industrial lease review is where a tenant confirms that the business plan, the building, and the contract actually fit together. It should happen before the letter of intent becomes too fixed and well before legal documents are executed.

For industrial tenants in Toronto and the GTA, lease terms affect more than occupancy cost. They can determine whether a company can run its equipment, store its inventory, receive shipments at required hours, expand into adjacent space, or leave without a damaging financial obligation. The asking rate matters, but it is only one part of the decision.

Start With the Real Occupancy Cost

Industrial leases are often quoted as net rent plus additional rent. That structure is common, but it requires careful review because the total cost is not clear until both figures and their assumptions are understood.

Net rent is the base rent paid for the premises. Additional rent commonly includes the tenant's share of property taxes, building insurance, common-area maintenance, management fees, utilities for common areas, and repairs to shared systems. In some buildings, it may also include costs that are less predictable, such as parking lot resurfacing, roof work, security upgrades, or administrative charges.

Ask for a detailed additional rent estimate and, where available, prior-year reconciliations. A low net rate can be offset by unusually high operating costs. A tenant should also determine whether the lease allows the landlord to recover capital expenditures and, if so, under what conditions and over what period.

HST should be included in cash-flow planning. So should direct utility costs, waste removal, racking, telecommunications, security, after-hours HVAC, and any special insurance required by the lease. The right question is not, “What is the rent?” It is, “What will this location cost us each month and each year under realistic operating conditions?”

Match the Lease to the Operation

A building's physical specifications and its permitted use need to support the operation from day one. This is especially relevant in a constrained GTA industrial market, where tenants may feel pressure to accept a space that is close enough. Close enough can become costly after move-in.

Confirm the Permitted Use

The use clause should be broad enough to cover the business as it operates now and as it may reasonably evolve. A narrowly written use clause can prevent a tenant from adding a related product line, light assembly process, showroom component, or distribution activity without landlord consent.

Zoning, fire code requirements, and site-specific restrictions should also be checked independently. The landlord's willingness to lease the space does not guarantee that every intended use is permitted. Businesses with outdoor storage, food-related operations, automotive uses, regulated products, hazardous materials, or high-power equipment need particularly careful diligence.

Review Loading, Access, and Hours

Loading doors, truck courts, clear height, shipping access, parking, and yard rights are operational terms, not minor details. A warehouse with the right square footage may still fail if trailers cannot maneuver safely or if the loading schedule conflicts with neighboring tenants.

The lease should identify any exclusive loading areas, shared access points, designated parking, and rules governing deliveries. If the operation requires early-morning or overnight activity, confirm that the lease and municipal rules do not restrict those hours. Do not rely on an informal statement that “other tenants do it.”

Identify Building Systems and Condition

Power capacity, sprinkler systems, HVAC, drainage, floor load, ventilation, and dock equipment should be assessed against the intended use. A tenant installing machinery, specialized racking, cooling equipment, or a significant electrical service may face major costs and approval requirements.

Document the condition of the premises before possession. Clarify who is responsible for repairs to the roof, structure, slab, mechanical systems, loading doors, and utilities. In a multi-tenant building, the landlord may retain responsibility for certain components, but lease language can shift meaningful costs back to the tenant.

Focus on the Clauses That Create Leverage or Risk

The economics of an industrial lease can change materially through clauses that receive less attention than rent and term. A careful industrial lease review should identify where flexibility is needed and where liability could outlast the tenant's use of the space.

The term and renewal provisions deserve close attention. A short initial term may preserve flexibility, but it can also expose a tenant to relocation risk in a tight market. A longer term may support investment in improvements and provide cost certainty, but it may become restrictive if the business contracts or relocates. Renewal options should state the notice deadline, rental-setting method, and whether the option is personal to the original tenant.

Assignment and subleasing rights are equally important. A business may need to sell, reorganize, downsize, or move before the lease ends. Landlord consent is normal, but the standard should be reasonable and the lease should address release conditions, recapture rights, and the landlord's ability to reject a replacement tenant.

Watch for personal guarantees and indemnities. Landlords often request them, particularly from newer companies or tenants with limited financial history. Their scope should be understood clearly. A guarantee tied to all lease obligations for the full term carries a very different risk than one capped by time or dollar amount.

Default provisions, remedies, and restoration obligations also require attention. Determine how much time the tenant has to cure a payment or non-monetary default. At the end of the term, the tenant may be required to remove leasehold improvements and restore the premises. That obligation can be expensive if it applies to electrical upgrades, office build-outs, racking, mezzanines, or specialized equipment.

Put Tenant Improvements in Writing

Industrial space is frequently delivered with some combination of existing office area, warehouse improvements, and a basic condition standard. Verbal promises about painting, dock repairs, lighting, office modifications, or landlord work should be converted into a written work letter or schedule.

The document should specify the scope of work, materials, approvals, timing, access before possession, and responsibility for cost overruns. If a tenant improvement allowance is offered, confirm what expenses qualify, when the allowance is paid, and whether unused funds can be applied to rent, furniture, cabling, or other costs.

Timing matters as much as budget. If the premises must be ready for a production launch or a move from an expiring facility, include clear delivery dates and consequences if landlord work is delayed. A rent commencement date tied to substantial completion may be more protective than a fixed calendar date, depending on the transaction.

Compare the Lease Against the Market, Not Just the Asking Rate

Lease negotiations are stronger when they are based on comparable alternatives and current market conditions. Rent is only one negotiating point. Free rent, fixturing periods, improvement allowances, annual escalations, renewal options, expansion rights, parking, signage, and repair obligations can all affect the long-term value of a deal.

The best structure depends on the tenant's priorities. A growing distributor may value expansion rights and assignment flexibility more than a modest rent concession. An established manufacturer investing heavily in a site may prioritize a long term, renewal certainty, and landlord contribution to building upgrades. A landlord, meanwhile, may place greater value on term length, credit quality, and certainty of occupancy than on a small increase in face rent.

This is where experienced brokerage and legal advice serve different but complementary roles. A commercial real estate advisor can assess market terms, property suitability, and negotiation strategy. Legal counsel can interpret and negotiate the enforceability of the lease language. Neither review should be treated as a substitute for the other.

Treat the Letter of Intent as a Business Decision

A letter of intent is often described as non-binding, but it can set the commercial framework that drives the final lease. Once the major points are accepted, changing them later becomes more difficult. The letter of intent should address the premises, term, rent, additional rent, deposits, use, improvements, possession, renewal options, assignment rights, conditions, and any brokerage arrangements.

It should also state which provisions are binding and which remain subject to lease negotiation, due diligence, and internal approvals. Vague language creates room for disagreement precisely when a tenant needs certainty.

A sound lease is not simply one with the lowest stated rent. It is one that gives the business a workable location, a clear cost structure, and enough flexibility to respond when operations change. Before committing, test the lease against the practical question that matters most: can the business operate here successfully for the full term, including the parts of the plan that may change?
