Changes are a comin to the New house price index

"On March 9, 2017, with the release of the January 2017 NHPI data, a number of important changes will be introduced to increase the relevance of the index series. The NHPI basket will be updated with new weights for the 2017 series and its coverage will be expanded to include four new census metropolitan areas (CMAs): Kelowna, British Columbia; Guelph, Ontario; Trois-Rivières, Quebec; and Sherbrooke, Quebec. The weights used for the 2017 series will be based on a price-adjusted three-year average of the value of building completions for each metropolitan area for 2014 to 2016.

Data for periods prior to January 2017 will be obtained by linking the new NHPI series, where possible, with indexes in CANSIM table 327-0046.

For the first time, separate series will be published for Toronto, Oshawa, Ottawa-Gatineau (Ontario part), Ottawa-Gatineau (Quebec part) and Greater Sudbury. The new indexes for Toronto, Ottawa and Greater Sudbury will be linked to those previously published for the following combined cities: Toronto-Oshawa, Ottawa-Gatineau (Ontario/Quebec) and Greater Sudbury and Thunder Bay respectively. Thunder Bay will no longer be included in the NHPI.

The index base period, for which the NHPI equals 100, will become December 2016.

CANSIM tables 327-0046 and 327-0050 will be archived and replaced by tables 327-0056 and 327-0057 respectively."

Got all that? No excuses for not knowing what's going on come March ;-)
