Ontario’s Small Business Property Tax Subclass: Which Properties Qualify, Who Has to Apply, and Whether a Net-Lease Tenant Ever Sees the Saving

Quick Answer

The final tax bill: what class and rates were applied

The city’s approved list for this taxation year

MPAC class, property code and current value assessment

The lease: how Taxes and additional rent are defined

The municipality’s opt-in by-law and its conditions

Item 1 — The most recent final tax bill: read the class line, not just the total

Start with the most recent final property tax bill the seller or landlord can produce. The City of Toronto says inclusion in the subclass is reflected in the final property tax bill, and that included owners need to take no further action — so the bill is where the status should show up first.

Look past the total to the classification and the tax rates applied. In Toronto the subclass sits inside the Commercial and New Commercial tax classes, which the City identifies as CT and XT. Two reading rules:

• A bill showing the subclass is evidence for that taxation year only. Approval is made “for the relevant taxation year” (O. Reg. 282/98, s. 23.0.8(5)).
• A bill showing only the ordinary commercial rate is not proof the property fails the tests. It means it was not on that year’s list — which is what Item 2 checks.

Ask for more than one year of final bills. A pro forma that carries one year’s reduced tax figure forward is assuming the status repeats.

Item 2 — The city’s published list of approved properties

The regulation requires the Program Administrator to give MPAC the list of properties, or portions of properties, approved for each taxation year, and to make that list available for public inspection by electronic means (O. Reg. 282/98, s. 23.0.8(6)). According to the City of Toronto (2026), the 2026 list was made available on the City’s Open Data portal on January 2, 2026.

Two details matter when you are checking a specific deal:

• Portions count. Because the list can approve part of a property, confirm which part is on it before applying the reduction to the whole building’s tax figure.
• Match by assessment roll number. It is the identifier the City asks for in any reconsideration request, and it avoids mistakes when a street address covers more than one listing entry.

The City’s subclass page also has an address search that tells you whether a property is inside the designated area used in Item 3.

Item 3 — MPAC classification, property code and current value assessment

Toronto’s tests for the 2026 taxation year turn on the property’s tax class, its CVA (current value assessment for 2026), and — depending on where it is — its lot size, floor area or MPAC property code. Every path requires Commercial or New Commercial classification (CT or XT). Figures below are from the City of Toronto’s page for the 2026 taxation year.

Path	CVA (2026 taxation year)	Other tests
Anywhere in the city	$10,000 to $1,000,000	None beyond class and exclusions
Inside Downtown and Central Waterfront, Growth Centres or Avenues (City map)	$10,000 to $7,000,000	Lot of 7,500 sq ft or less, or gross floor area of 2,500 sq ft or less (the GFA test applies only to commercial condominiums)
Strip plaza, anywhere in the city	$10,000 to $7,000,000	MPAC property code 425, 429 or 430; two or more attached retail establishments with shared or common parking; site area and gross floor area each 25,000 sq ft or less

The three strip-plaza codes are, in the City’s words, 425 Neighbourhood Shopping Centre with anchor, 429 Community Shopping Centre, and 430 Neighbourhood Shopping Centre without anchor — so the MPAC code on the assessment, not the listing’s marketing description, decides which row applies.

Excluded whatever the numbers: properties in the office building, shopping centre, parking lot and vacant land classes; land already in the Creative Co-location Facility subclass or the Vacant Land subclass; property with no affixed building or structure; and land for which a demolition permit has been issued. The regulation itself adds that the land must not be vacant land and must be used by the owner or a tenant for a small business as the municipal by-law defines it (s. 23.0.9(1)(a), (d)).

Item 4 — The lease: how Taxes and additional rent are defined

No statute or regulation moves this reduction from landlord to tenant. Part III.0.2 of O. Reg. 282/98 says nothing about rent, and the City of Toronto’s only guidance is that tenants of eligible properties “should speak to their landlord about receiving this reduction.” Whether a tenant’s costs fall is therefore a contract question, answered by the lease. Read these clauses together:

• The definition of Taxes or Realty Taxes. Is the tenant paying a share of the taxes actually levied, or a fixed or estimated amount?
• The additional rent or TMI mechanics. Are monthly estimates reconciled against the actual bills at year-end, and on what timetable?
• The base of the share. Is the tenant paying the bill for its own roll number, or a proportionate share of a building-wide bill?
• Who acts if the listing is wrong. The regulation gives the reconsideration request to an owner of land (s. 23.0.11(2)), and Toronto states that tenants cannot dispute. Whether the lease obliges the landlord to pursue one is, again, only a lease question.

Where the clause passes through the actual bill, a smaller bill means a smaller base for the pass-through. Where the lease sets some other method, that method governs. For a buyer, the same clauses tell you the other direction: if the property later leaves the subclass, whether the higher bill can be recovered from tenants or comes out of your income.

💡 If the saving is part of your numbers — a buyer underwriting income, or a tenant budgeting occupancy costs — confirm it in both columns: this year’s list, and the lease clause that says where the bill goes.

Item 5 — The municipality’s opt-in by-law (outside Toronto, check this first)

Provincially, the subclass is an option a municipality has to take up. It applies for a property class only if the single-tier or upper-tier council has passed a by-law opting in (O. Reg. 282/98, s. 23.0.8(2)). That by-law can:

• limit the subclass to part of the municipality, and set different requirements in different parts (s. 23.0.8(3)–(4));
• add eligibility conditions of its own, including what counts as a small business (s. 23.0.9(1)(a), (e));
• decide whether owners must apply at all. An application is needed only if the by-law requires one (s. 23.0.10(1)); where it does, land approved for the previous year that still qualifies may be approved without a fresh application (s. 23.0.10(4)).

The size of the municipal reduction is set by provincial regulation, or by a by-law choosing a percentage within a range the regulations set (Municipal Act, 2001, s. 313.1(1); City of Toronto Act, 2006, s. 278.1(1)). The education portion follows: Education Act s. 257.7(3) reduces it in the same manner, and O. Reg. 400/98 s. 12(3) applies that rule to small business subclasses from the 2023 taxation year on.

Outside Toronto, whether the subclass exists, where, on what terms and at what percentage is decided by each municipality’s by-law — so Items 1 to 4 only make sense once you have read it. Toronto’s thresholds above do not carry over. In Toronto itself, the City states owners do not need to apply.
