Property Tax in Ontario and Legal Considerations

Real Estate Law

Updated on 

Owning property in Ontario entails various financial obligations, including property tax. This levy is vital for financing municipal infrastructure maintenance, public education, and emergency services. However, the complexities surrounding property tax and associated legal considerations often confuse homeowners and potential buyers. This article aims to elucidate the essential aspects of property tax in Ontario and highlight some of the legal considerations.

Understanding Property Tax Calculation

Property taxes in Ontario are calculated based on the assessed value of the property as determined by the Municipal Property Assessment Corporation (MPAC). MPAC evaluates properties based on several factors, including location, lot dimensions, and living area.

The Formula

Property taxes are calculated using the Current Value Assessment of a property, as determined by the Municipal Property Assessment Corporation (MPAC), multiplying it by the combined municipal and education tax rates for the applicable property class.

  • Municipal Tax Rate: Set by the local municipal government, this rate varies depending on the type of property and the municipality.
  • Education Tax Rate: This rate is set by the provincial government and is standard across Ontario.

The MPAC Assessment

MPAC conducts property assessments every four years. However, due to the COVID-19 pandemic, the 2020 assessment update has been postponed.

  • Notice of Assessment: Property owners receive a Notice of Assessment from MPAC detailing the current assessed value of the property, which serves as the basis for calculating property taxes.
  • Request for Reconsideration (RFR): If you disagree with the MPAC valuation, you can file an RFR.

Ownership Structures

Different property ownership structures can have distinct legal and tax implications.

  • Sole Ownership: Property owned by a single individual or entity will have straightforward tax implications, with the property tax being the sole responsibility of the owner.
  • Joint Ownership: Legal complications can arise if the property is jointly owned and there is disagreement on how property taxes are allocated among the owners.

Property Tax Liens

Failing to pay property taxes can lead to a tax lien against your property. The municipality can eventually sell the property to recover the unpaid taxes.

  • Notice: Before a sale can happen, the municipality must provide notice to the property owner.
  • Redemption Period: The property owner usually has a redemption period during which they can pay the overdue taxes to avoid the sale of the property.

Municipal Tax Policy Changes

Local governments occasionally revise property tax policies, which can have legal implications.

  • By-Laws: Municipalities might introduce new by-laws affecting property tax rates, and it’s essential to understand how these changes impact your tax obligations.


Understanding property tax in Ontario involves grasping how it’s calculated, the role of MPAC assessments, and the legal considerations that come into play, particularly regarding ownership structures, tax liens, appeals, and municipal policy changes. Given the complexities of the associated legal landscape, consulting with professionals in the field, including real estate lawyers and tax consultants, is highly advisable to ensure that you are both compliant with the law and adequately protecting your financial interests.

If you plan to purchase real estate in Ontario, it is essential to seek legal advice to ensure that you know all the current rules and regulations. A real estate lawyer can guide and advise you before you make a purchase decision and help you understand the legal implications of buying pre-construction.
