The agency says the combined metropolitan region of Toronto and Oshawa, as well as the Montreal region, were the top contributors to the increase.
Toronto and Oshawa prices were up due to market conditions, while higher material and labour costs and new building code requirements pushed prices up in Montreal.
Monthly prices declined 0.2 per cent in Charlottetown and were down 0.1 per cent in the combined metropolitan region of Sudbury and Thunder Bay, Ont.
Prices were unchanged in 11 of the 21 metropolitan regions surveyed in October.
On a year-over-year basis, the index was up 2.4 per cent compared with October 2011.
