How MPAC assesses properties

MPAC’s job is to accurately classify and value properties in Ontario in compliance with the Assessment Act and regulations established by the Ontario Government.

To establish your property’s assessed value, MPAC’s assessment professionals analyze property sales in your area. These sales provide the basis for assessed values. Our experts work in our 33 offices located across the province.

We continually collect and update detailed information for every property in Ontario to ensure that similar property types are valued consistently within the market area.

This method is called Current Value Assessment. It is used by most assessment jurisdictions in North America.

Property Information

In addition to sales, our experts regularly analyze property information through a number of sources, including:

  • land title documents;
  • building permits;
  • on-site property inspections and communication with property owners; and
  • income and expense information (for apartment buildings, hotels and others).

MPAC's database contains over two billion pieces of data, and is one of the most detailed in the world. Like all assessing authorities, MPAC is able to determine accurate values for large groups of properties based on common data and mass appraisal techniques.

In addition to recent sales, MPAC looks at the key features of every property. Although as many as 200 different factors are considered when assessing the value of a residential property, there are five major factors that account for 85% of the value:

Property Classification

In addition to valuing your property, MPAC also classifies your property. There are seven major property classes: Residential, Multi-Residential, Commercial, Industrial, Pipe line, Farm and Managed Forests. There are also several sub-classes for properties with specific or unique characteristics.

Some properties may belong to more than one class. For example, if a small business is being operated out of the home, the property would fall into two classes (Residential and Commercial).

A Simple Test

To find out if your assessed value is accurate, simply ask yourself this question – could you have sold your property for its assessed value on the valuation date listed on your Property Assessment Notice?  If the answer to this question is yes, then your assessed value is probably correct.

We want to make sure the classification and assessed value of your property are accurate.  If you don’t think they are, call us.

Property Taxes

When your municipality/local taxing authority sets property tax rates, they are applied to the assessed value of your property to determine your property taxes.  Questions about your local tax rate should be directed to your municipality/local taxing authority.  Education tax rates, which are set by the Ontario Government, are also applied to the assessed value when determining property taxes.
