Municipal taxation – Overview
Property taxation is the primary way that Municipalities raise funds to provide services. In Ontario, property taxation is regulated through the Municipal Act, 2001 and supporting regulations. Municipalities are required to levy property taxes on all real property, which includes land and improvements.
Property tax classes are assigned to properties or portions of a property based on the property's use as defined in Section 3 of the Assessment Act.
Ontario has eight mandatory tax classes that all Municipalities must have at a minimum:
- Managed forest
There are an additional six optional classes that Municipalities can choose to adopt to define property use further:
- Shopping centre
- Parking lots and vacant land
- Office building
- Large industrial
- New multi-residential
- Professional sports facility
There are eight optional subclasses that Municipalities can choose to adopt even further to define property use:
- Commercial excess land
- Industrial excess land
- Industrial vacant land
- Commercial small scale on-farm business
- Industrial small scale on-farm business
- Farmlands pending development class I
- Farmlands pending development class II
- Small business
Ottawa has adopted all six optional classes and eight optional sub-classes to have the highest property use definition and promote property taxation equity. Council can make changes to the optional classes adopted through the annual tax policy.
What is a tax ratio?
Municipalities in Ontario have the authority to apply differential taxation rates to different property classes through tax class ratios. A tax ratio is the proportion by which a class or sub-class tax rate compares to the residential class tax rate, which has a base ratio of 1.0. For example, a property with a tax ratio of 2 would pay twice the municipal tax amount as a similarly valued residential property. These ratios allow different tax burdens between the different property classes.
Why do tax ratios exist?
Ratios allow municipalities to manage the shifting of the property tax burden between classes. Annual tax shifts happen between classes due to different rates in property assessment values across different classes. The City historically adopts ratios that mitigate tax shifting and keep the tax burden the same in each class.
What are the current tax ratios?
Below are the 2023 tax ratios as approved by Council:
|Property class||Tax ratio|
|Parking Lots and Commercial Vacant Land||1.30|
|Professional Sports Facility||1.92|
Provincial legislation allows the City to set the optional and mandatory subclass tax ratios as a percentage of the applicable class tax ratio. Council has approved the adoption of the following tax ratios for the property subclasses:
|Property subclass||Tax ratio|
|Commercial Excess Land||100% of the applicable commercial property class tax ratio|
|Industrial Excess Land||100% of the applicable industrial property class tax ratio|
|Industrial Vacant Land||65% of the applicable industrial property class tax ratio|
|Small Business Subclass||85% of the applicable property class tax ratio|
|Small Scale On-Farm Business||25% of the applicable commercial/industrial property class tax ratio|
|Farmlands pending Development Class I||75% of the residential property class tax ratio and the corresponding tax rate percentage reduction for the awaiting residential, commercial and industrial property tax classes|
|Farmlands pending Development Class II||No tax rate|
Property tax distribution by class
While there are eight broad tax classes, more than three-quarters of Ottawa's property value is in the Residential tax class, accounting for 67% of total property tax revenue. The Residential, Commercial and Multi-Residential broad classes make up 98% of the total taxes levied. The table below outlines the proportion of property assessment and property tax by broad class:
How are my property taxes calculated?
There are three components used to calculate the amount of property taxes you pay:
- Assessed value of property
The assessment value of a property is determined by the Municipal Property Assessment Corporation (MPAC). The City does not determine assessment values.
- Municipal tax rate
Tax rates are determined through calculations, which involve the budgetary tax levy requirement approved in the budget setting exercise, the total current value assessment by class, and tax policy effects.
- Education tax rate
The annual education tax rates for all Ontario properties are set by the Province and reflect the overall provincial reassessment changes by class.
Your residential property taxes are calculated using this formula:
- Assessed value x municipal property tax rate = amount of municipal property tax
- Assessed value x education tax rate = amount of education property tax
- Municipal property tax + education property tax = your property taxes *
*Please note that, if applicable, other charges such as local improvements, municipal drains or business area improvement charges might be added to the tax bill.
Will the significant rise in real estate prices increase my property taxes?
To determine a property's assessed value, MPAC conducts a province-wide reassessment every four years to update the assessed value of all Ontario properties. The last assessment was carried out in 2016, in which all property owners received a Property Assessment Notice. The assessed property value is then phased in over the four-year cycle, with the last cycle being 2017 to 2020. The Ontario government has postponed the planned reassessment that was scheduled in 2020 to 2023. This means that assessments for the 2022 and 2023 taxation years will continue to be based on the same valuation in effect for the 2021 taxation year unless there have been any physical changes to the property.
A significant increase in property value does not automatically translate to a property tax increase. Municipalities cannot benefit from market value increases. The City of Ottawa adjusts the baseline tax rates downward to account for overall assessment increases and collect the same revenues. If a property's annual assessment value increase is higher than the average of all properties in the same class, the property will see a higher than normal tax increase. Conversely, if a property's assessment value increase is less than the average of all properties in the same class, the property will see a lower than normal tax increase. If all properties were to increase the same amount, there would be no difference in their property tax amount, outside of the annual increase approved by Council if there have been no changes to the property.

What you get for your property taxes
The City of Ottawa provides many vital services to residents each day, which directly impacts the quality of life that residents expect. One-quarter of a residential property tax bill is effectively set or mandated by the Province. Education taxes are set by the Province and collected by the City. Also, the City is required to administer Provincially mandated programs such as employment and financial assistance (Ontario Works), long-term care and affordable housing.
See below to where your property taxes went for every $100,000 in assessment in 2023:

|Provincially Mandated Programs||$97||$97||$97|
|Transit & Para Transpo||$199||$59||$14|
|Roads & Traffic||$99||$99||$99|
The provincial government sets the rates that fund the education system in Ontario.
Provincially mandated programs:
The Province requires the City to pay for social service programs such as: social assistance, child care services, social housing, public health and long-term care, and to pay for assessment services provided by MPAC.
The City funds three watershed Conservation Authorities (Rideau Valley, Mississippi Valley and South Nation).
Transit and Para Transpo:
Funds public transit services based on your service delivery area.
