MPAC has revised the assessments of all pit and quarry properties in Ontario to reflect the Divisional Court’s decision on the long-standing pit and quarry Assessment Review Board (ARB) appeals.  
 
As part of this update, changes to classification and methodology have been made in order to reflect the approach outlined in the ARB decision.   
 
Property owners received a Property Assessment Notice in November, updating their property’s assessed value and classification for the 2024 property tax year. 
 
All assessed values reflect the January 1, 2016 valuation date. If property owners disagree with their property’s assessed value and/or classification, they can file a Request for Reconsideration (RfR) with MPAC, free of charge, by April 2, 2024.
