In 2004, Canadians, on average, used 329 liters of water per person per day.
Information from Environment Canada
Municipal water use, including residential, commercial, and public uses, and the water lost from reservoirs and pipes amounted to about 9.5% of all withdrawals in Canada in 2006.
This figure does not include rural areas where water use is not measured. If rural domestic uses were included, this figure would rise to about 11.5%
