Significance
• In some countries, fresh water is a scarce resource; however, in Canada, there is an abundance of fresh water.
• The fact that Canada has vast quantities of this precious resource does not, however, justify wastefulness.
• Comparing average daily flow of water per capita will show which communities are saving fresh water and which are not.

Core Indicator
• Total average daily flow of water is measured by the relationship between the total water residential use and the population served water.
• Residential use specifies water that was used by individuals, not for commercial or other use.
• Of all the water used in Canada 53.5% is used residentially (as opposed to commercial use).

National Trend Since 2001
• Since 2001, residential water use per capita has been decreasing in Canada (see following chart).
• The largest decrease was between 2006 and 2009 (a decrease of 16.2%).
• Environment Canada suggests that this decline may be due to a number of factors including: climatic variables, socioeconomic variables, higher rates of metering and increasing water and sewer prices.

Canada’s Major CMAs
• In 2009, water use per capita in St. John’s (710.0L) was the highest among Canada’s major CMAs and over twice the national average (274.0L) (see following chart).
• Second highest was Montréal (434.9L).
• London had the lowest residential water use per capital at 160.1 litres per person per day, followed by Edmonton at 180.8 litres.

CMA Trends (1999 to 2009)
• The absolute change in water consumption within the last decade for major CMAs has varied a lot between regions, however, 9 of the 15 communities followed the national trend of decreasing water use (see following chart).
• St. John’s had the highest water use growth of 71.5 litres, followed by Montréal (up 48.6L).
• Québec (down 306.7L) and Hamilton (down 196.5L) had the greatest decreases in water consumption.

The Impact of Billing
• Environment Canada suggests that the method for billing water has a large effect on the amount of water consumed per capita.
• Residents in Nova Scotia, for example, consumed more than double the amount of water when they were billed a flat rate.
• Canadians who are charged a meter rate based on volume seem to use much less water.
