Assessment information

The assessed value of a property is commonly referred to as the current value assessment or CVA. The CVA is an estimate of the market value of a property at a fixed point in time (the valuation date), or the amount the property would sell for in an open market on a given date (i.e. what a willing buyer would pay a willing seller for the property).

In Ontario, the Municipal Property Assessment Corporation (MPAC) assigns the assessed value and tax class to all properties every four years. Municipalities have no authority to assign, alter or change the assessed value or tax class of property.
