Commercial real estate in Ontario
The commercial side of Ontario real estate: how to specialize, what Course 4 covers, the licensing path, commission structures, and where commercial differs from residential under TRESA. With practice questions and exam prep aligned to the Humber curriculum.
Licensing path: same registration, different specialization
Ontario does not issue a separate "commercial real estate license." A registered salesperson under RECO can legally trade in any property class — residential, commercial, industrial, multi-residential, vacant land, and leasing. The licensing path is the same as for any other agent: complete the Humber pre-registration program (Courses 1-4 plus Simulations 1 and 2), pass the Salesperson Final Exam, register with a brokerage, and complete articling.
Specialization happens through brokerage placement and post-registration training, not licensing. Most commercial agents start at a generalist brokerage, then move to a commercial-focused team (CBRE, JLL, Colliers, Cushman & Wakefield, Avison Young, or boutique commercial firms) once they have basic deal experience. Some boutique residential brokerages also have small commercial divisions for cross-over deals (e.g. mixed-use multifamily).
What Course 4 covers
Course 4 (Commercial Real Estate Transactions) is the dedicated commercial course in the Humber sequence. It assumes you've completed Courses 1-3 and the residential simulations, then drops you into a different way of thinking about real estate: properties as cash-generating assets rather than primary residences, leases as multi-year commercial contracts, and valuation rooted in income approach rather than comparable sales.
Major topic blocks:
- Property types: office (Class A/B/C), retail (street-front, plaza, anchor-tenanted, regional), industrial (general-purpose, distribution, flex, manufacturing), multi-residential (apartment buildings), special-purpose (medical, hospitality, educational)
- Leasing fundamentals: gross leases, net leases (single, double, triple), modified gross, percentage rents, escalation clauses, common area maintenance (CAM), recoveries
- Valuation: capitalization rate (NOI ÷ purchase price), gross income multiplier (GIM), gross rent multiplier (GRM), discounted cash flow basics
- Financing: debt service coverage ratio (DSCR), loan-to-value (LTV), commercial mortgage terms, vendor take-back financing
- Due diligence: environmental site assessments (Phase I, II, III), zoning verification, title review, lease audits, estoppel certificates
- Documentation: commercial Agreement of Purchase and Sale forms, Commission Agreement (Form 200 series for commercial), confidentiality agreements, letters of intent
Course 4 is the most quantitatively heavy of the four. Math sections cover cap-rate calculations, NOI derivation, lease-rate problems with escalations, and DSCR scenarios. See the full Course 4 outline and practice question count on our course page.

Commercial leasing in Ontario
The commercial leasing market in Ontario is large and lease-driven. Most commercial brokerage activity is leasing rather than sales, especially in office and industrial. Lease commissions generate predictable per-deal income; sales generate larger but less frequent paydays.
Ontario's Commercial Tenancies Act (CTA) governs the landlord-tenant relationship for commercial leases. Unlike the residential RTA, the CTA gives parties wide latitude to negotiate; almost everything is contractual, with the lease document controlling. Common pitfalls in Course 4 questions include holdover rents, fixturing periods, demolition clauses, exclusive-use covenants, and assignment vs. sublet rights — all topics where the lease language usually overrides any default rule.
Net-lease structures dominate institutional-grade commercial. In a triple-net (NNN) lease, the tenant pays base rent plus property taxes, insurance, and CAM. Calculating the all-in occupancy cost requires breaking out base rent, property tax recoveries (often expressed as $/sf), insurance recoveries, and CAM (which varies by property and is capped or unbounded depending on the lease). Course 4 tests this regularly.
The path to commercial brokerage
Becoming a registered broker (vs. salesperson) is more relevant in commercial than residential. Many commercial firms structure compensation around broker-level registration so senior agents can supervise junior team members and run dedicated practice areas. The path: register as salesperson, gain at least 2 years of fully-registered experience (post-articling), complete the Humber Broker Pre-Registration Program, pass the Broker Final Exam, and re-register with RECO as a broker. See our complete licensing-path guide for the full timeline.
Most commercial agents stay non-managing brokers — registered as brokers but working under another brokerage's licence. This unlocks higher splits and the ability to handle more complex transactions (large investment sales, ground leases, joint ventures) without taking on the operational burden of running a brokerage.

Frequently asked questions
How do I become a commercial real estate agent in Ontario?
You complete the same Humber pre-registration program as residential agents (Courses 1-4 plus Simulations 1 and 2), pass the Salesperson Final Exam, register with RECO under a brokerage that handles commercial work, and complete the articling program. There is no separate "commercial license" in Ontario — Course 4 (Commercial Real Estate Transactions) is the dedicated commercial-content course in the registration path. After registration you specialize in commercial through your brokerage placement and continuing education.
Is there a separate commercial real estate license in Ontario?
No. Ontario uses a single registration framework under TRESA and RECO. A registered salesperson or broker can trade in any real estate (residential, commercial, industrial, leasing, investment) the moment they are registered. Specialization is a matter of training, brokerage focus, and continuing education, not a separate license class.
What does Course 4 cover?
Course 4 (Commercial Real Estate Transactions) covers commercial property types (office, retail, industrial, multi-residential, special-purpose), commercial leasing fundamentals (gross vs. net leases, percentage rents, common area maintenance), commercial AOP forms, due-diligence frameworks, capitalization rates and valuation, environmental site assessments, financing structures (debt service coverage, GRM/GIM/cap rate), and the regulatory differences between commercial and residential transactions under TRESA. It is the most numerically dense of the four salesperson courses.
How long does it take to specialize in commercial?
Most agents who go commercial join a brokerage with an established commercial team after registering as a generalist salesperson. The first 1-2 years are typically apprenticeship: shadowing senior commercial brokers, doing market research, building tenant/landlord relationships. By year 3-5, an agent with consistent commercial focus has a market segment (e.g., GTA industrial leasing, Mississauga retail, or downtown Toronto office) and a reliable deal flow.
How are commercial commissions calculated?
Commercial commissions are deal-by-deal and rarely follow a fixed percentage. Sales typically run 1-5% of the transaction price (lower percentages on larger deals — 1% on a $20M industrial sale is normal). Leases are often calculated as a multiple of one month's rent, a percentage of the total lease value, or a flat per-square-foot fee, with terms varying widely by brokerage and asset class. Co-op splits are negotiated each deal rather than published on MLS.
What is the salary range for commercial real estate agents in Ontario?
Highly variable because commercial is commission-based and deal cycles are long (3-12+ months from listing to close). First-year commercial agents often earn under $30,000 net while building a pipeline. Established commercial brokers in major markets clear $200,000-500,000+ per year. Top commercial brokers in institutional asset classes (industrial portfolios, downtown office) reach $1M+. Volatility is much higher than residential.
