For Markham landlords and real estate investors, the annual rent increase guideline is one of the most important numbers of the year, and the 2026 figure sends a clear signal. Ontario's rent increase guideline for 2026 is 2.1%, the lowest cap in four years, down from 2.5% in 2025.
Understanding what this means for your rental property returns, your investment strategy, and your tenant relationships is essential. Michael John Lau, top real estate agent in Markham Ontario and CPA/CMA, breaks down the 2026 rent guideline for landlords.
What the 2026 Guideline Actually Means
Ontario's rent increase guideline for 2026 is 2.1%, which is the maximum most landlords may raise rent without approval from the Landlord and Tenant Board. The guideline is calculated using the Ontario Consumer Price Index and is capped at a maximum of 2.5% by law. Which is why 2026's figure of 2.1% represents the lowest cap in four years.
In real dollar terms, for a Markham rental unit renting at $2,200 per month, the maximum legal increase in 2026 is $46.20, bringing the new rent to $2,246.20. For a unit at $2,800 per month, the maximum increase is $58.80.
The Rules Governing the Increase
A landlord must give at least 90 days' written notice using the official LTB Form N1 before any rent increase can take effect. Rent can only be increased once every 12 months for the same tenant, not once per lease renewal. Informal notices (emails, texts, verbal) are not legally valid.
Looking ahead, the guideline for 2027 has been set at 1.9%. Even lower than 2026, continuing the trend of modest guideline increases.
What This Means for Markham Landlords
The 2.1% guideline, the lowest in four years, has real implications for landlord returns and strategy.
Compressed Rent Growth
For landlords with sitting tenants in rent-controlled units, the 2.1% guideline caps annual rent increase well below the rate of increase in many operating costs. Property taxes, insurance, maintenance, utilities.
Vacancy Decontrol Dynamic
Rent controls apply only to existing tenancies. When a tenant voluntarily moves out, the landlord may set the new rent at market rate for the next tenant. Turnover allows a reset to market.
Post-2018 Exemption
Units first occupied after November 15, 2018 are often exempt from the guideline. For these newer units including many Downtown Markham condos, landlords can raise rent by any amount with proper notice.
Notice Compliance
90-day written notice via LTB Form N1, once per 12 months per tenant, no informal notices. Compliance is non-optional and non-tenant-specific rules do not shift.

The Strategic Picture for Rental Investors
The 2.1% guideline sits within a broader rental market context that Markham investors need to understand.
The rental market has softened. Immigration moderation has reduced rental demand across the GTA, and the completion of the 2021-2022 condo construction wave has added rental supply. This has softened rents in many segments. Meaning the gap between guideline-capped in-place rents and current market rents has narrowed, reducing the upside from vacancy decontrol in the current market.
The long-term supply picture supports rents. As discussed in the supply cliff analysis, the historic collapse in condo construction (lowest since 1996) is creating the conditions for a future rental supply shortage. As the current supply wave is absorbed and the construction collapse constrains future supply, rental demand meeting reduced supply supports rent growth over the longer term, benefiting patient rental investors.
Why Newer Units Offer More Flexibility
For investors purchasing Markham rental property, the post-2018 exemption makes newer units, including Downtown Markham condos near York University, attractive for the rent-setting flexibility they provide, alongside their appeal to the growing student and professional rental demand.
Unit Category | Guideline Application | Investor Implication |
|---|---|---|
Pre-November 15, 2018 units | Subject to 2.1% 2026 guideline | Compressed rent growth on sitting tenants, turnover unlocks market rent |
Post-November 15, 2018 units | Often exempt from guideline | Rent-setting flexibility with proper notice |
New construction Downtown Markham condos | Post-2018 exemption applies | Investor flexibility plus growing student demand |
Older detached rental homes | Subject to guideline | Long-term hold strategy with turnover reset opportunity |

Factor the 2.1% guideline and the vacancy decontrol dynamic into your return projections. And recognize that the current rental market softness sits against a longer-term supply picture that supports rents for patient investors. For those building or holding a Markham rental portfolio, the strategy should account for both the near-term guideline constraints and the long-term supply-demand fundamentals.
