POPULATION: As of July 1, 2013, the population of Canada was estimated at 35,158,300 inhabitants, an increase of 404,000 inhabitants last year, which is equivalent to that observed on July 1 2011 to July 1, 2012., and for 30 years similar to average annual earnings. The population growth rate, except for the period between 1986 and 1990, showed little variation over 30 years, ranging from 0.8% to 1.2%. The population estimates released today are now based on 2011 Census counts adjusted to account for census net undercoverage and incompletely enumerated Indian reservations. For the year ending June 30, 2013, population growth was higher in the Western provinces, while it was generally lower in the Atlantic provinces and negative in Nova Scotia (-0 .5%) Population growth exceeds the national level by more than 1.2 percent, in Alberta more than 3.4 percent, in Nunavut more than 2.5 percent and in Saskatchewan more than 1.9 percent. In Alberta, strong growth is explained by record levels of international migration and interprovincial migration to the province. Low natural increase and interprovincial migration losses, which reached a six-year high, explain the weak growth in the Atlantic provinces.

In order to provide municipalities with a clean, safe and reliable drinking water supply, the guidelines define the basic parameters that every water system (public, semi-public and private) should aim to achieve. In addition to federal guidelines, provincial and territorial water authorities impose water quality and drinking water standards. Municipal water utilities are responsible for meeting provincial water quality regulations and targets are met. In order to ensure the supply of safe drinking water, stricter water quality regulations have been adopted and the costs of maintaining water quality standards have increased significantly. For example, capital costs have been estimated at over $800 million to meet Ontario's water quality regulatory requirements...
