Description: The article "Freshwater in Canada" provides up-to-date statistics on freshwater supply and demand. The report includes includes maps, charts and tables for each of Canada's 25 drainage regions. It also provides data on some of the factors that influence the supply and quality of freshwater.

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.

Description:

Data from the Census are mapped, showing how Canada's population changed from 1981 to 2006.

Description:

This annual report provides supporting information to the main Canadian Environmental Sustainability Indicators report, which presents indicators for water quality, air quality and greenhouse gas emissions. This report provides contextual information on the human activities that have influenced the environmental indicators. Socio-economic information is divided into three broad categories: land, population and economy. Selected data from the Censuses of Population and Agriculture are also provided in the form of regional profiles for major drainage areas and sub-drainage areas of Canada. The indicators are intended to assist those in government responsible for developing policy and measuring performance, while also helping individual Canadians who want to know more about the trends in their environment.

The indicator reports from 2005 to 2007 can be found below. All later indicator reports can be found on Environment Canada's site: www.ec.gc.ca/indicateurs-indicators/.

Description:

Data from the Industrial Water Survey are mapped, showing how the cost of acquiring water varies across the country.

Description:

This bulletin extends the analysis to present selected socioeconomic characteristics of the population by type of watershed. This analysis is based on Statistics Canada's 2001 Census of Population data tabulated according to drainage sub-basins.

Description:

The objective of this study was to estimate and map livestock manure production by the environmental geography unit known as the Sub-Sub-Drainage Area (SSDA) in 2001 and to calculate the change in manure production over the 1981-2001 period.

Description: This bulletin groups watersheds according to the share of their population that is designated as "census rural" in order to profile the rural versus urban demographic structure of watersheds across Canada.
