In Ontario, if your current lease includes “all-inclusive” utilities, your landlord cannot force you to start paying for a newly installed smart sub-meter. If you voluntarily agree to take on the utility bill, the landlord is legally required to permanently reduce your monthly rent using a specific Landlord and Tenant Board (LTB) formula.
Renting an all-inclusive apartment in cities like Toronto, Ottawa, or Mississauga used to be the golden standard for tenants. You paid one flat fee, and you never had to worry about the winter heating bill or the summer air conditioning costs. However, as electricity costs continue to rise across Canada, many property management companies and landlords are trying to shift this financial burden onto tenants by installing “smart sub-meters” (suite meters) for each individual unit.
While landlords are legally allowed to upgrade their buildings and install these sub-meters, they cannot simply rip up your existing lease and hand you a new hydro bill. The Residential Tenancies Act (RTA) heavily protects existing tenants from sneaky utility downloading. Whether you live in a high-rise in Brampton or a multiplex in London, understanding your rights regarding utility transfers is critical to protecting your wallet. In this guide, we will outline the step-by-step process a landlord must follow and what you can do if they break the rules. 📊
Step-by-Step Process for Switching to Sub-Metered Utilities
If a landlord wants to switch an existing tenancy from all-inclusive utilities to tenant-paid sub-meters, they must follow a strict, highly regulated legal process. Here is what should happen.
Step 1: The Landlord Must Seek Your Consent
The most important rule in Ontario is that a utility transfer must be completely voluntary for an existing tenant. Your landlord cannot force you to sign a new lease or agree to take on the hydro bill. They must present you with the option, and you have the absolute right to say “no.” If you decline, you keep your all-inclusive rent, and the landlord continues to pay the utility bill based on the sub-meter readings. 🗏️
Step 2: Receiving the Mandatory Information Package
If the landlord wants you to agree, they must give you a formal information package. This package must detail the contact information of the sub-meter provider, outline any administrative or billing fees the provider charges, and provide an estimate of what the electricity would have cost for your unit over the past 12 months. This transparency allows you to make an informed financial decision.
Step 3: Calculating the Mandatory Rent Reduction
If you agree to take on the utility bill, the landlord is not allowed to keep collecting the same amount of rent. Because they are no longer paying your hydro, they must permanently reduce your monthly rent. The LTB has strict formulas for this, usually based on the actual electricity usage of your unit over the previous 12 months.
Step 4: Signing the Agreement
Once you agree to the rent reduction and the new terms, both you and the landlord must sign a formal written agreement to alter the lease. Only after this document is signed can the sub-meter company begin billing you directly for your monthly usage. ✍️
Step 5: Filing a T3 Application if Rules are Broken
If your landlord installs a sub-meter, forces you to pay the bill without your consent, or refuses to reduce your rent, you should take immediate legal action. You can file a Form T3 (Tenant Application for a Rent Reduction) with the Landlord and Tenant Board. The LTB can order the landlord to refund you for the utility bills you illegally paid and officially reduce your rent going forward. ⚔️
How Much Does This Process Cost in Ontario?
Defending your rights against illegal utility downloading involves minor administrative costs, but the financial payoff of keeping your rent low is massive.
| Service / Expense | Estimated Cost in CAD (2026) | Details |
|---|---|---|
| LTB Form T3 Filing Fee | $53.00 | Fee to file a formal rent reduction application with the LTB. |
| Sub-Meter Admin Fees | $10 to $25 per month | Extra fees charged by third-party billing companies (if you agree to the switch). |
| Sub-Meter Setup Deposit | $50 to $200+ | Many hydro companies require a security deposit from the tenant to open an account. |
| Legal Representation | $1,000 to $2,500+ | Hiring a paralegal to represent you at the LTB hearing. |
Remember, if you win your case at the LTB, the adjudicator will generally order the landlord to reimburse you for the $53 filing fee. 💵
How Long Does the Process Take?
If you choose to file a T3 application because your landlord illegally downloaded the utility costs, you must act relatively quickly. You generally have exactly 12 months from the date the landlord stopped paying the utility to file your application. Once your Form T3 is submitted, waiting for a hearing date at the heavily backlogged LTB typically takes 8 to 14 months. You must continue to pay your legal rent while waiting for the hearing.
Frequently Asked Questions (FAQ)
Can the landlord cut off my power while installing the meter?
Yes, but only temporarily and with proper notice. A landlord can legally shut off the power for a short, reasonable period to perform the electrical upgrades, provided they give you at least 24 hours written notice detailing the exact time the power will be out.
What if I am a brand new tenant moving into the building?
The rules protecting all-inclusive leases only apply to existing tenants. If you are a new tenant signing a brand new lease, the landlord can legally require you to pay for the sub-metered electricity right from day one, as long as it is explicitly written into your Standard Ontario Lease.
Can I withhold my rent if they force me to pay hydro?
No. Under Ontario law, you should generally never withhold your rent, even if the landlord is breaking the rules. Withholding rent gives the landlord grounds to evict you for non-payment. Always pay your rent and file a Form T3 to get the money back through legal channels.
Does switching to a sub-meter affect my rent control?
No. Agreeing to lower your rent and take on the utility bill does not void your rent control protections. The building remains subject to the standard provincial annual rent increase guidelines, assuming it was first occupied for residential purposes before November 15, 2018.
Who pays to fix the sub-meter if it breaks?
The hardware belongs to the landlord or the third-party sub-metering company. As a tenant, you are not financially responsible for repairing or replacing the actual meter if it malfunctions, unless the damage was caused by your willful or negligent behaviour.
