In order to deal with the volatility inherent in a system based on real estate values, it is necessary to place a limit on individual property value increases resulting from each new assessment. That limit or ceiling should relate to the historic increase in Ontario real estate values which have, over extended periods of time, been roughly double the rate of inflation. The government could quickly develop a logical and easily implemented ceiling on assessment increases. This simple step will stabilize the system and bring about a predictable and more equitable property tax regime in Ontario. This reform should be implemented before the devastating impact of the 2008 assessment hits Ontario property owners.
