Regional highlights

Prices rose in every province on a year-over-year basis in October.

Increases in the property tax and other special charges index (priced annually in October) were larger in Newfoundland and Labrador, Prince Edward Island and Nova Scotia compared with the previous year, but smaller in Ontario and Western Canada. Property tax rates decreased in New Brunswick (-0.1%) and in Quebec (-1.7%), where Bill 166 harmonized Quebec's provincial school taxes and introduced a property owner's exemption.

Prices for fuel oil and other fuels rose at a faster rate in Atlantic Canada in October, as colder temperatures set in.

Canadian consumers paid 3.9% less for natural gas compared with October 2017.

In Ontario, energy prices fell 2.4% on a month-over-month basis, following the termination of the carbon cap and trade program introduced in January 2017. Prices for gasoline (-4.0%) and natural gas (-1.0%) declined month over month in October.

  Note to readers

Upcoming methodology change

The release of the November 2018 Consumer Price Index will reflect changes in methodology for the telephone services index, as well as the introduction of new data sources for pricing smartphones, to improve the overall quality and relevance of the index.

Users should note that changing methodological elements of any index may result in variations in the series. As such, the interpretation of the 12-month price change indicator should be made with caution, particularly in the year following the implementation of a new methodology.

Real-time data tables

Real-time data table 18-10-0259-01 will be updated on December 10.
