Thinking about becoming a home inspector in Ontario? You're not alone. With a strong real estate market, flexible hours, and the ability to run your own business, home inspection is one of the better trades-adjacent careers available right now.
The good news: Ontario does not require a government-issued license to practice as a home inspector. The realistic news: if you want clients, referrals from real estate agents, and the ability to charge professional rates, you need education and certification.
Here's exactly how it works.
Is Home Inspection Licensed in Ontario?
As of 2026, Ontario does not have mandatory government licensing for home inspectors — unlike British Columbia and Alberta, where licensing is required by law. Anyone can technically call themselves a home inspector in Ontario without formal credentials.
In practice, this means the market self-regulates through professional associations. Inspectors who carry recognized credentials get real estate agent referrals and client trust. Those who don't, struggle to build a business.
Step 1: Complete an Accredited Training Program
Your first step is completing a recognized home inspection training program. The most widely accepted options in Ontario are:
Humber College / Carson Dunlop
The most recognized program in Ontario. Carson Dunlop is deeply embedded in the Ontario market and their curriculum is aligned with OAHI, ASHI, InterNACHI, CAHPI, and CSA standards. Humber College partners with Carson Dunlop to deliver the program. This is the route most Ontario inspectors take.
Durham College
Offers a home inspection program in partnership with Seneca College and Carson Dunlop. Courses are available monthly online, making it accessible for working adults.
InterNACHI School
Fully online, self-paced. Lower cost than college programs. Well-recognized internationally. Good option if you want to move faster or complement a college program.
Budget roughly $3,000–$5,000 for a full training program depending on the provider and format.
Step 2: Get Certified
After completing your training, you'll want certification from one of the major recognized associations:
OAHI (Ontario Association of Home Inspectors)
The Ontario-specific body. Being OAHI-registered carries strong credibility with Ontario real estate agents. Requires passing exams, completing field reports, and meeting experience requirements.
InterNACHI (International Association of Certified Home Inspectors)
Global certification, widely recognized. The Certified Professional Inspector (CPI) designation requires passing an online exam, completing coursework, and submitting mock inspection reports. Membership starts at $49/month or $499/year, which includes access to all training materials and CE courses.
Many Ontario inspectors hold both. You don't have to choose — they're complementary.

Step 3: Get Your Business Set Up
Before your first paid inspection, you'll need a few things in place:
- Business registration — Register as a sole proprietor or incorporate in Ontario. Sole proprietor is the fastest and cheapest to start.
- Errors & Omissions (E&O) insurance — Not legally required in Ontario but many real estate boards require it. InterNACHI members get discounted E&O coverage. Budget $1,000–$2,500/year.
- Equipment — Inspection tools (moisture meter, electrical tester, flashlight, ladder) typically run $500–$2,000 to start. You can upgrade over time.
- Report software — You'll need a way to write, deliver, and store professional reports. This is what clients and agents see — it matters more than most new inspectors expect.

Step 4: Write Your First Reports
Your first 50 inspections are where you build speed and confidence. Most new inspectors take 3–4 hours on site plus 2–3 hours writing the report. Experienced inspectors complete both in under 3 hours total.
Report writing software makes a huge difference at this stage. Software with pre-built narratives means you're not writing from scratch on every inspection — you're selecting and editing, which is dramatically faster.
Expert Check includes 1,300+ pre-built narratives aligned with Ontario inspection standards. New inspectors can complete a professional report in under an hour from their first day. At $29.99 CAD/month it's also the most affordable professional-grade option in Canada.

The majority of inspection business in Ontario comes through real estate agent referrals. Your first 6–12 months should include consistent outreach to local agents — presenting yourself, sharing sample reports, and staying visible.
Agents refer inspectors they trust to deliver a clear, professional report quickly. Your report software is part of your pitch.
How Long Does It Take?
From zero to first paid inspection: most people complete training and get certified in 3–6 months. Some move faster with online-only programs. The business-building phase — getting consistent agent referrals and regular bookings — typically takes 12–18 months.
