Understanding an MPAC Property Assessment

About MPAC 

The Municipal Property Assessment Corporation (MPAC) is an independent corporation and carried out the assessment and classifications of all properties, as mandated by the Government of Ontario. Every four years, MPAC updates properties' assessed values. The most recent valuation was completed for January 1, 2016.

MPAC is one of the most important bodies in establishing how much taxes property owners pay each year. While the City of Toronto establishes a rate annually, the value that rate is applied to, is determined by MPAC. Consequently, a home that is valued at a new, lower rate, by MPAC may pay less in taxes, even when municipal property tax rate in increased. Conversely, a rise in the municipal property tax rate may be inflated significantly in total dollar amounts by MPAC assessing a property at a new, higher value.

If you have concerns or questions about the assessed value of your property, there are several steps you can take.

For Property Owners

First, check for any factual errors in your Property Assessment Notice. MPAC can correct these.

Second, determine if the value is accurate. If you do not believe your property could be sold for the assessed value, you may have grounds to seek a reconsideration.

Third, you can compare your property's assessment against comparables. www.aboutmyproperty.ca can be accessed with the Roll Number and Access Key provided by MPAC in your most recent notice. This site allows you to compare your property to neighbours' and use an interactive map to create a detailed report for any reconsideration.

Fourth, you can contact MPAC directly by one of the hotlines, fax numbers, or contact forms hosted on the MPAC website.

Fifth, you can file a Request for Reconsideration. This free of charge service is available to property owners and a form can be found here.

Sixth, MPAC will send you a confirmation and review your file – typically in 180-240 days.


For Concerned Communities

Sometimes MPAC will assess a property on the basis of possible use that conflicts with its current use and the principles of local planning policies. It is important that property owners contact MPAC directly, as per the steps above. However, there are also practices and legislation that impact how the assessment process takes place.

In cases of social enterprise being valued according to commercial or residential development scenarios (and similar situations), residents should contact their Member of Provincial Parliament. Municipal policies allow for one-time project-related grants and tax rebates for qualifying heritage buildings, for instance, but the longer term assessment rates are entirely established by MPAC via the direction of the Provincial Legislature.

Where the above steps are being taken, it may also be helpful for property owners to investigate any area planning policies that might conflict with the assessments they have received. An interactive zoning bylaw map can be found on the Toronto website here. Where there are outstanding questions regarding the implications of those bylaws, or to understand what additional policies may apply to their property, owners may also wish to contact Planning staff directly via the staff phone numbers and emails listed on that page.
