The Teranet-National Bank House Price Index(tm) is estimated by tracking observed or registered home prices over time using data collected from public registries. All dwellings that have been sold at least twice are considered in the calculation of the index. This is known as the repeat sales method, a complete description of the method is given at www.housepriceindex.ca. The Teranet-National Bank House Price Index(tm) is an independently developed representation of average home price changes in six metropolitan areas: Ottawa,Toronto, Calgary, Vancouver, Montreal and Halifax. The national composite index is the weighted average of the six metropolitan areas. The weights are based on aggregate value of dwellings as retrieved from the 2006 Statistics Canada Census. According to that census, the aggregate value of occupied dwellings inthe metropolitan areas covered by the indices was $1.168 trillion, or 53% of the Canadian aggregate value of $2.207 trillion. All indices have a base value of 100 in June 2005. For example, an index valueof 130 means that home prices have increased 30% since June 2005.
