Media Kit

MPAC is committed to providing the media with timely, accurate and comprehensive information about property assessment in Ontario.

MPAC is the largest assessment jurisdiction in North America, assessing and classifying more than five million properties with an estimated total value of $2.78 trillion.

Our role is to accurately assess and classify all properties in Ontario in compliance with the Assessment Act and regulations set by the Government of Ontario.

We are an independent, not-for-profit corporation funded by all Ontario municipalities, accountable to the Province, municipalities and property taxpayers through a 13-member Board of Directors.

  • MPAC’s province-wide Assessment Updates of property values have met international standards of accuracy.
  • Our assessors are trained experts in the field of valuation and apply appraisal industry standards and best practices. More than 300 of our valuation staff hold one or more designations from recognized accrediting bodies.
  • MPAC delivers innovative products and value-added services to banks, insurance companies, the real estate industry and a number of other assessment jurisdictions across Canada.
  • MPAC completes a province-wide Assessment Update every four years based on a set valuation date.
  • In 2016, MPAC updated the assessed value of every property in Ontario based on a legislated valuation date of January 1, 2016.
  • These 2016 assessed values will be used by municipalities as the basis for calculating property taxes for the 2017-2020 property tax years.
  • Under the phase-in provisions in the Assessment Act, an increase in assessed value is introduced gradually over four years. A decrease in assessed value is introduced immediately.
  • MPAC continues to review properties during non-Assessment Update years as new homes are built, owners renovate, structures are demolished and properties change use. MPAC also mails Notices to property owners to reflect changes in ownership, value, classification or school support.
  • The next province-wide Assessment Update will take place in 2020 based on a January 1, 2019 valuation date.
