    Operation and maintenance (O&M) costs associated with the acquisition and treatment of water will vary by treatment technology, annual production volumes and the type of source water processed. This study analyzes the data collected by the 2007 Survey of Drinking Water Plants to illustrate how O&M costs vary by these factors.

    This analytical article "Freshwater Supply and Demand in Canada", provides information on Canada's freshwater supply as well as the demands placed on it. New research done within Statistics Canada is complimented by information from other sources, including other federal government departments, international bodies and scientific journals.

    Section 1 of this article compares Canada's renewable water resources to those of other countries, introduces key highlights and presents a short water primer. Section 2 quantifies Canada's renewable water resources (annual water yield), shows how water yield has changed from 1971 to 2004, and presents graphs of water yield by month for four regions of the country. Section 3 quantifies economic and residential water use in Canada and concludes with an analysis of the relationship between supply and demand. A glossary of terms used in the publication is available in Section 4.

    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.

    Water is essential for crop production, whether it is provided by rain or irrigation. Although relatively few farms in Canada irrigate, this use of water can represent a significant portion of water use in some areas of the country. This article presents information on the use of irrigation in 2007.

    Quantifying how Canada's water yield has changed over time is an important component of the water accounts maintained by Statistics Canada. This study evaluates the movement in the series of annual water yield estimates for Southern Canada from 1971 to 2004. We estimated the movement in the series using a trend-cycle approach and found that water yield for southern Canada has generally decreased over the period of observation.

    In 2008, Statistics Canada conducted the first Agricultural Water Use Survey. This pilot survey is part of the Canadian Environment Sustainability Indicators initiative and collects information on volumes of water used for irrigation, irrigated areas, irrigation practices and the quality of water used for agricultural purposes. This technical paper describes the methodology used for the pilot survey and includes recommendations for future cycles of the survey. The validation process seems to indicate that the method used to estimate the volumes of water used and the irrigated areas calculated underestimates the results. The report gives recommendations to minimize this bias in the next iterations of the survey. First, it is recommended to simplify the level of information collected by the survey; to review the sampling methodology; and to examine other means of collecting information on volumes of water used for irrigation. This pilot version of the survey remains a reliable source for consistent data on agricultural water use.

    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.

    The objective of the present study is to understand and explain how the Canadian Council of Ministers of the Environment (CCME) Water Quality Index (WQI) behaves, and at the same time determine its limitations to make a better use of it in the future. In order to do so, four data sets were made available to us thanks to participation of the following provinces: Newfoundland, Ontario, British Columbia and Quebec.

  • Surveys and statistical programs – Documentation: 5128
    Description: The purpose of this survey is to obtain information on the quality of surface water in Canada on an annual basis. Data are obtained from water quality monitoring programs managed by Environment Canada, provincial departments, or under federal-provincial agreements. At present, the freshwater quality indicator is presented as a national histogram of three consecutive years worth of results of the water quality index, calculated at individual monitoring sites across the country. The histogram groups values into five categories: poor, marginal, fair, good and excellent.
