Ontario never proclaimed its 2017 home-inspector law — there is no licence to get. The real path: OAHI membership, training, and the RHI credential.
Applies in: Ontario
Ontario is the odd province out for home inspection. The Home Inspection Act, 2017 passed with Royal Assent, but it was never proclaimed into force — e-Laws still carries the note "THIS ACT IS NOT YET IN FORCE." That means there is no provincial licence to apply for, no mandatory exam, no required training, and no insurance rule. Anyone can legally call themselves a home inspector in Ontario today.
This guide follows the law as it stands now, because building your career on a licence that does not exist yet is how people waste a year.
With no government gatekeeper, the industry's credential is voluntary, and it runs through the Ontario Association of Home Inspectors (OAHI). OAHI became a self-regulating body by provincial law in 1994 (PR. 158) and is the only organization granted the right to issue the R.H.I. (Registered Home Inspector) initials.
OAHI's membership categories run from Student (non-practising) and Applicant up through Candidate and Associate to RHI, the highest level. Apply as a Student or Applicant member as early as possible.
There is no government-mandated curriculum, so the industry standard is the Carson Dunlop 10-subject home inspection certificate: roofing, structure, electrical, HVAC, plumbing, exterior, insulation, interior, communications, and professional practice.
Your options, all verified current:
Two more courses sit on the mandatory list for the top credential: the Ontario Building Code Part 9 courses (The House - Health and Safety, The House - Building Envelope), issued as Ministry of Municipal Affairs and Housing certificates with a 70% passing grade.
Membership tiers are the actual career path:
OAHI does not publish a single fixed duration. The binding constraint is 150 fee-paid inspections plus upgrades in set periods. Ask OAHI for the current period limits before enrolling.
Get your insurance in place before the first paid inspection. E&O plus CGL is the industry expectation even though Ontario law does not require it, and real-estate agents, who supply most of the referrals in this business, will not send clients to an uninsured inspector.
The Registered Home Inspector designation is OAHI's highest level: the highest educational requirements the association sets, a set number of paid inspections, and continuing education plus mandatory upgrading to keep it. This is the credential that lets you compete on something other than price in an unregulated market.
There is no provincial licence application to file. What you do need:
| Item | Verified figure |
|---|---|
| Carson Dunlop training | $3,934 (St. Lawrence) to $4,995 (direct) |
| OBC Part 9 courses | Ministry certificates; check MMAH for current fees |
| OAHI membership dues | Check oahi.com for current dues by tier |
| E&O + CGL insurance | Get quotes before your first paid inspection; BC requires $1M minimum each |
Training vendors quote the course price and stop there. Budget the dues and insurance too, or the first year will surprise you.
Indeed reports an $82,349 average in Ontario (5 salaries reported, updated August 10, 2026; typical range $62,469 to $108,556). Carson Dunlop puts the typical range at $40,000 to $70,000 in year one, $70,000 to $100,000 in years two to three, and $100,000-plus once established. Treat every salary figure as a small-sample snapshot: Indeed's Ontario average rests on five reported salaries, and self-employed income swings with the referral network, not the credential.
The honest version: the ceiling is referral-driven. Most inspections come through real-estate agents, so income tracks your agent network more than your credential. Employed inspectors trade ceiling for a steady pipeline; the self-employed keep more per inspection and build their own client base.
Ontario credentials do not transfer automatically, because both provinces actually licence the work:
| Carson Dunlop program, direct (10 online courses) | $4,995 |
|---|---|
| Same program at St. Lawrence College (part-time) | $3,934 |
| Same program at Sheridan College (part-time) | $4,211 |
No. Ontario passed the Home Inspection Act, 2017, but it was never proclaimed into force, so there is no provincial licence and no mandatory training, exam, or insurance requirement. Anyone can legally call themselves a home inspector in Ontario. That is exactly why the voluntary credential from the Ontario Association of Home Inspectors (OAHI) matters: it is the only thing that distinguishes a trained inspector from someone with a flashlight and a business card.
Training is self-paced: college programs allow up to three to five years to finish, and Conestoga requires all courses within four years of acceptance. A motivated student can complete the coursework in months. The slow rung is the OAHI Associate level, which requires 150 fee-paid inspections, realistically a year or more of active work. Plan on roughly 1.5 to 3 years from zero experience to the full RHI designation.
The industry-standard Carson Dunlop 10-course program costs $4,995 directly from Carson Dunlop (approved as a vocational program under the Ontario Career Colleges Act, 2005 for Ontario students). The same program through colleges lists lower: $3,934 at St. Lawrence College and $4,211 at Sheridan College. On top of training, budget for OAHI membership dues and errors-and-omissions plus general-liability insurance quotes before your first paid inspection.
Carson Dunlop's Home Inspection Training Program is the 10-subject certificate the Ontario industry treats as the baseline: roofing, structure, electrical, HVAC, plumbing, exterior, insulation, interior, communications, and professional practice. Ontario colleges including Conestoga, Sheridan, and St. Lawrence deliver it in partnership with Carson Dunlop, and completing it fulfils the OAHI baseline academic requirements. Courses typically need a 70% grade or better. Two Ontario Building Code Part 9 courses (Health and Safety, Building Envelope) from the Ministry of Municipal Affairs and Housing are also mandatory baseline accreditation courses for the RHI.
RHI stands for Registered Home Inspector, the highest credential from the Ontario Association of Home Inspectors, which was granted the right to issue those initials under provincial law (PR. 158) in 1994. The ladder runs: Student or Applicant member, then Candidate (core education, practical training, peer review), then Associate (150 fee-paid inspections plus academic upgrades), then RHI, which demands the highest educational requirements, a set number of paid inspections, and ongoing continuing education to keep.
Ontario law does not require it, because there is no licence to hold. You should still carry errors-and-omissions (E&O) and commercial general liability (CGL) insurance before taking any paid inspection: real-estate agents will not refer uninsured inspectors, and one missed defect can mean a lawsuit. For scale, British Columbia makes both mandatory at $1 million minimum each for its licensed inspectors.

No, and mixing them up costs people jobs. Municipal building inspectors are city employees who enforce the Ontario Building Code on construction sites and need OBC qualifications (BCIN). Home inspectors do private, visual, pre-purchase inspections for buyers and sellers, and in Ontario they answer to no regulator at all. They are different jobs, different employers, and different training paths.
Not directly: both provinces licence the work. British Columbia requires a Consumer Protection BC licence (150 hours of approved education, one of four approved exams, 50 hours shadowing a licensee, a peer recommendation letter, company registration, a municipal business licence, a criminal record check, and $1 million minimum E&O and CGL policies; the 2026 application fee is $1,461). Alberta licences both the business and the inspector through Service Alberta: approved training or an approved designation, a $10,000 security bond, E&O insurance, a criminal background check, and a Service Alberta-approved client contract. Alberta accepts a Consumer Protection BC licence as a qualifying credential.
