    Description:

    Households in Canadian municipalities often have options when choosing the type of water they drink at home and whether they treat it prior to drinking it. The reasons why they might choose to treat their water could be aesthetic or there might have been problems in the past that are influencing their decisions today. Using data from the 2007 Households and the Environment Survey, the author explores some of the factors governing these decisions for households in a selection of Canadian municipalities.

    Description:

    In this paper, we present the methodology developed by Statistics Canada to calculate the average annual water yield for Canada. Water yield, for the purposes of this paper, is defined as the amount of freshwater derived from unregulated flow (m3 s-1) measurements for a given geographic area over a defined period of time. The methodology is applied to the 1971 to 2000 time period.

    This research was conducted to fill data gaps in Statistics Canada's water statistics program. These gaps exist because estimates of freshwater flow for Canada have not been calculated regularly and have been produced using a variety of methods that do not necessarily generate comparable results. The methodology developed in this study produced results that are coherent through space and time. These results will be used in the future to investigate changes in water yield on a more disaggregated basis.

    To achieve the water yield estimate a database of natural streamflow observations from 1971 to 2000 was compiled. The streamflow values were then converted to a runoff depth and interpolated using ordinary kriging to produce spatial estimates of runoff. The spatial estimates were then scaled to create a National estimate of water yield as a thirty-year average. The methodology and results were then validated using a stability analysis and several techniques involving uncertainty. The result of the methodology indicates that the thirty-year average water yield for Canada is 3435 km3.

  • Technical products: 16-256-X
    Description:

    This report presents details on the data sources and methods underlying the freshwater quality indicator as it was reported in the Canadian Environmental Sustainability Indicators, 2007 (16-251-XWE). The national freshwater quality indicator provides an overall measure of the suitability of water bodies to support aquatic life in selected monitoring sites in Canada.

    Details on this indicator reported after 2007 can be found on Environment Canada's site: www.ec.gc.ca/indicateurs-indicators/

  • Technical products: 21-601-M2007087
    Description:

    This paper describes the efforts and results of Statistics Canada to produce comparable agricultural water use estimates at the national, provincial and sub-sub-drainage area level for reference year 2001.

    Release date: 2007-11-13

  • Technical products: 16-505-G
    Description:

    Part of Statistics Canada's Econnections: linking the environment and the economy statistical series, this publication describes in detail the conceptual frameworks, data sources and empirical methods used to compile the Canadian System of Environmental and Resource Accounts (CSERA). Designed to be compatible with the accounting frameworks of the System of National Accounts, the CSERA allows users to easily analyze the linkages between economic activity and the environment in terms of material and energy flows, environmental expenditures and natural resource stocks. This publication will be of interest to researchers in both the economic and environmental fields who want to familiarize themselves with the accounting concepts of the CSERA. It is a companion volume to Environment-economy indicators and detailed statistics (catalogue no. 16-200-XKE), another product in the Econnections series.
