The Revenue Division is responsible for the billing of interim, final and supplementary property taxes; tax, provincial offences and miscellaneous receivables; payment processing and cashiers; review and appeal of property assessment information received from the Municipal Property Assessment Corporation (MPAC); and property tax policy.

This site will explain who sets property taxes, where the information comes from upon which 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 City collects property taxes on behalf of the City of Mississauga, Region of Peel, and the Province of Ontario (Education). Each level of Government is responsible for its own tax rates.

Assessment & Tax Legislation

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 - MPAC

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.

MPAC completed the last province-wide reassessment in 2012 based on a market valuation date of January 1, 2012 with municipalities using 2012 property assessment values for the 2013, 2014, 2015 and 2016 taxation years.

To provide an additional level of property tax stability and predictability, the market increases in the assessed value of your property between 2008 and 2012 will be phased-in over four years.  The phase-in program does not apply to decreases in assessed value.  If there has been a decrease in your property's assessed value compared to 2008, it will be reflected immediately in the 2013 tax year.  The change in assessed value and phased-in assessment values for the 2013 to 2016 property tax years are listed on your 2012 Property Assessment Notice.

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, www.mpac.ca .
