The Municipal Property Assessment Corporation (MPAC) assesses all properties in Ontario.

The chances for errors are built into the system. MPAC uses a sophisticated computer program, which takes into account elements such as the size of a home, where it is located, the number of bathrooms, bedrooms, and other features, whether it has been recently renovated and what similar properties sold for recently.

ArGil will appeal the assessment on your home or seasonal property if the “Current Value Assessment” is over $4,000,000.  Please call us or fill out the form on our Assessment Quote page.

ArGil analyzes your current tax bill and reviews comparable properties to determine whether or not an RFR should be filed with MPAC. We present our findings to you and obtain your approval to move forward with an RFR.


As your representative, ArGil negotiates with MPAC to achieve a reduction. If negotiations are unsuccessful, we litigate the appeal at the Ontario Assessment Review Board.

Filing the Appeal

We file a Request for Reconsideration (RFR) with the Municipal Property Assessment Corporation (MPAC), as is mandated by the Ontario Assessment Act. If the RFR is not successful with MPAC, and if deemed appropriate, we file a complaint with the Ontario Assessment Review Board.


Upon the completion of the reassessment, you are provided with a report that clearly outlines the new assessment value and the savings you will receive over the entire four-year period.

Is Your Reassessment Too High?
