property taxes are based, who plays what role in the process leading from the creation of
taxation policy to your tax bill, and many other tax questions.

the Province of Ontario (Education). Each level of Government is responsible for its own tax
Assessment and Tax Legislation - Province of Ontario
The Provincial Government sets the legislative framework for assessment and taxation in
Ontario. It does this by creating legislation, called Provincial Statutes. The Government also
creates regulations, which are authorized under the Statutes. The principal ministry involved
in setting assessment and taxation policies is the Ministry of Finance, through the Assessment
and Municipal Acts. These laws may be viewed at www.eLaws.ca.
Assessed Value - Municipal Property Assessment Corporation
The Municipal Property Assessment Corporation (MPAC) is responsible for assessing all
property in Ontario. It operates under the authority of the Municipal Property Assessment
Corporation Act. Every municipality in Ontario is a member of the Corporation. The Corporation
is governed by a Board of Directors who are appointed by the Minister of Finance. MPAC does not
set assessment policy but it does administer these policies. Its main responsibility is to
calculate assessment values and to classify properties according to their use, for each of the
over four million properties in Ontario. These values are also provided to municipalities on an
annual assessment roll. The City, Region and the Province use these values when they calculate
property taxes and education taxes.
Additions and improvements to your property will create a change to the market value. For
questions concerning assessment and property valuation, please contact the Municipal
Property Assessment Corporation office (MPAC). Call 1-866-296-6722 or visit the MPAC web site
