Ontario Rent Control in 2026: What the 2.1% Guideline Means for Your Cash Flow

Ontario's rent increase guideline for 2026 is 2.1%, the lowest cap in four years and down from 2.5% in both 2024 and 2025. For tenants in eligible units, this is welcome relief. For landlords with rent-controlled units, it is one more year where the revenue side of the equation grows slower than costs. This post explains exactly how the guideline works, which units it applies to, and what the math looks like on a real property when costs are rising faster than 2.1%.

How the Guideline Works

The rent increase guideline is the maximum percentage a landlord can raise rent for most existing tenants in a calendar year without approval from the Landlord and Tenant Board. For 2026, that maximum is 2.1%. The guideline is set annually by the Ontario Ministry of Municipal Affairs and Housing based on the provincial Consumer Price Index measured from June to May of the prior year.

The guideline is capped at 2.5% by legislation, which is why it held at 2.5% for three consecutive years from 2023 to 2025 when inflation ran higher. The 2026 drop to 2.1% reflects cooling inflation in that measurement period.

Key procedural rules every landlord must follow: rent can only be increased once every 12 months per tenant; a minimum of 90 days written notice is required using the LTB Form N1; verbal or informal notice is not valid and an increase served incorrectly may be unenforceable. Above-guideline increases are available through an LTB application for specific circumstances such as major capital expenditures or significant municipal tax increases, but the process takes time and approval is not guaranteed.

Which Units Are Covered and Which Are Exempt

The guideline applies to most private residential rental units first occupied on or before November 15, 2018. This includes older apartments, houses, condos, and basement units where the tenancy began before that date.

Units first occupied after November 15, 2018 are exempt from rent control. For these units, landlords can increase rent by any amount with proper 90-day notice, and can reprice freely on turnover. New builds, additions completed after November 2018, and new basement apartments created after that date fall into this category.

This distinction matters enormously for investment decisions. A 2019 or newer condo in Toronto theoretically allows market-rate rent increases on turnover. But as CMHC data shows, Toronto purpose-built vacancy rates hit 3% in 2025 for the first time since the pandemic, and turnover rents have softened. The legal ability to reprice on vacancy is less valuable in a market where finding a replacement tenant at a higher rent takes longer and sometimes requires incentives.

The Cost Gap in Real Numbers

The core problem for landlords with rent-controlled units is not the 2.1% figure in isolation. It is the gap between 2.1% revenue growth and the actual rate of cost increases.

Consider a Toronto condo renting for $2,200 per month with a sitting tenant in a pre-2018 unit. The landlord can raise rent by $46.20 per month in 2026, bringing it to $2,246.20. Meanwhile:

• Property insurance has been rising 5% to 12% annually in many Ontario markets. On a $150/month insurance cost, a 7% increase is $10.50 more per month.
• Property taxes in Toronto increased 9.5% in 2024 and a further 6.9% in 2025. On $500/month in property tax, a 7% average is $35 more per month.
• Maintenance and CapEx costs track broadly with inflation and trade labour costs, which have run well above 2.1% in recent years.

A rough tally: the landlord gains $46 per month in rent while costs increase by $50 to $80 per month. The net cash flow position deteriorates by $4 to $34 per month in 2026 alone, even before any mortgage renewal impact.

Over five years at these relative rates, a property that started at $0 cash flow can drift to $200 to $400 per month negative purely from the compounding cost gap, with no renewal shock required. Add a renewal at 4.5% or 5.0% and the picture deteriorates much faster, as outlined in The Mortgage Renewal Wave Hitting Ontario Landlords in 2026.

What This Looks Like Over a 5-Year Term

Projecting the same Toronto condo with a sitting tenant forward five years, applying 2.1% rent growth annually and 4% annual cost growth (conservative):

The net operating income before mortgage payments erodes by $14 over five years from cost growth alone. Not dramatic in isolation, but this is the baseline before any mortgage cost increase. If the mortgage renews at a higher rate over this period, the total cash flow impact compounds significantly. The 30-Year View in Rental Analyst models this compounding over a full projection horizon so you can see where the trajectory leads before committing to a hold decision.

Turnover: The One Lever Rent-Controlled Landlords Have

When a sitting tenant vacates, the landlord can set any rent for the new tenant. There is no vacancy decontrol restriction in Ontario; the property does not become permanently exempt. The new rent simply starts a new rent control baseline for that tenancy.

In 2022 and 2023, this was a powerful lever. A unit turning over at $1,800 could be re-listed at $2,400 or more in a tight market. In 2025 and 2026, the repricing opportunity on turnover has narrowed. CMHC reported that average two-bedroom turnover rents declined in Toronto, Vancouver, Calgary, and Halifax in 2025 as vacancy rose and competition increased. Landlords in some areas are offering incentives, including one month of free rent, to fill vacant units.

For landlords with rent-controlled units that are significantly below market, turnover remains a meaningful financial event. But the assumption that any vacancy can be repriced sharply upward should be stress-tested against current comparable rents in the specific building and neighbourhood, not assumed based on 2022 conditions.

How to Model Your Rent Control Exposure

The most important thing a landlord with rent-controlled units can do right now is run the numbers forward. Specifically:

• Enter your actual current rent, not market rent. If your tenant is paying $1,900 and market is $2,300, model $1,900. The gap tells you the real exposure and what changes at turnover.
• Apply a realistic rent growth assumption. The 30-Year View lets you set a rental growth rate. At 2.1% (matching the guideline), you see the trajectory of a long-tenanted unit. At 0%, you see the worst case. At 3% or 4%, you see what turnover repricing could do.
• Model the renewal rate separately. Use the Renewal tab to layer in the mortgage renewal rate on top of the rent control projection. This is where most of the cash flow risk concentrates: a capped revenue trajectory meeting a step-change in mortgage costs at renewal.

The Units That Are Exempt and What That Changes

If you own a unit first occupied after November 15, 2018, the 2.1% guideline does not apply to your sitting tenant. You can raise rent by any amount with proper 90-day Form N1 notice, and you can reprice freely when the unit turns over.

In practice, raising rent aggressively on a sitting tenant carries tenant relations and vacancy risk. Most landlords with exempt units still apply moderate increases to avoid turnover costs. The real advantage of exemption is on vacancy: the freedom to price to current market without a regulatory ceiling.

If you are uncertain whether your unit is exempt, check your lease for an exemption clause, confirm the date the building was first occupied for residential purposes, and if in doubt, consult the LTB or a qualified paralegal before issuing any increase above 2.1%.
