Beyond the LTB: What Ontario’s Rental Housing Enforcement Unit Can (and Can’t) Do

The LTB isn’t your only option. Ontario runs a second, enforcement-focused route that can put a landlord — or a tenant — in front of a judge. Here’s what it can and can’t do.

I’m Arthur Zhao, a broker in the GTA with 12 years in the business. When a tenant calls me after their landlord has changed the locks or shut off the heat, the advice they’ve already heard from friends is almost always the same: take it to the LTB. That isn’t wrong — but it’s only one of two doors. Ontario runs a second one that most renters, and plenty of landlords, have never heard of: the Rental Housing Enforcement Unit. It doesn’t settle your dispute or hand you a cheque. It does something the LTB can’t — investigate a breach of the law and prosecute the other side in court. Knowing which door to walk through, and when to use both, is the difference between venting and getting a result.

Most renters only know one door

The LTB — the Landlord and Tenant Board — is the body everyone hears about: you file an application, you get a hearing, you get an order. It’s a civil forum, and its job is to resolve the dispute between you and the other party and, where warranted, order a remedy. But some landlord (or tenant) conduct isn’t just a private disagreement — it’s an offence under the Residential Tenancies Act, 2006 (the RTA). Offences are handled by a different body entirely — one that answers to the government, not to you.

What the Rental Housing Enforcement Unit actually is

The RHEU is a unit of Ontario’s Ministry of Municipal Affairs and Housing. Its mandate is narrow and specific: it investigates conduct that breaks the RTA and, when the evidence supports it, lays charges and prosecutes the landlord or tenant before the Ontario Court of Justice. A conviction results in a fine — and here’s the part that surprises people — that fine is paid to the province, not to the person who complained. The RHEU is not a tribunal, it does not hold hearings, and it does not award you anything.

LTB vs RHEU: the difference that actually matters

What kind of conduct is actually an offence?

Not every landlord–tenant disagreement is an offence. The ones the RHEU can act on are specific breaches of the RTA. The most common include:

• Illegal lockouts — changing the locks or retaking the unit without following the Act;
• Cutting off a vital service — withholding or interfering with hot or cold water, fuel, heat, electricity or natural gas;
• Illegal entry — entering the unit without a proper reason, without notice, or at improper times;
• Harassment — threatening or interfering with a tenant to pressure them out;
• Illegal charges — overcharging rent, charging unauthorized fees, refusing to give rent receipts, or failing to return a deposit;
• Disobeying an LTB order — a separate offence on top of the original dispute;
• Suite-meter violations, plus specialized rules for care homes and mobile home parks;
• Giving false information to the enforcement unit.

How a complaint actually moves

The process is deliberately staged — it usually tries resolution first and reserves prosecution for conduct that isn’t fixed. Here is the path from start to finish.

If you’re a landlord, this is what draws a prosecution

The RHEU cuts both ways — tenants can be prosecuted too — but in practice most charges target landlord conduct. The behaviours that most reliably invite a file: locking a tenant out instead of getting an LTB eviction order, shutting off utilities to force someone out, charging illegal fees or deposits, entering without notice, harassing a tenant to leave, and — a big one — ignoring an LTB order you’ve already lost. With the maximum fine now up to $100,000 for an individual and $500,000 for a corporation, the cost of “self-help” enforcement is far higher than doing it the lawful way.

What the RHEU won’t do for you

Set your expectations honestly. It won’t get you compensation — there is no payout to the person who complained. It won’t restore your tenancy or reverse an eviction. It won’t take an anonymous complaint. And it won’t give you legal advice or predict whether charges will be laid or will succeed. If your housing is on the line right now, treat the RHEU as a slow, punitive lever rather than an emergency remedy — for urgent relief, an LTB application (and, in a genuine emergency, other authorities) will matter more.
