The 5-year mobility measures the percentage of the population aged five years or older who moved (changed address) in the five years preceding Census Day, 1996. The values are generally low. Three-quarters of the places have a figure below the Canadian average and the median for the entire set of...

This map indicates the degree of reliance of each of the 298 communities on forest-related industries. The index range spans the complete range from 50% up to 100% with most communities having values in the lower half of this range. Even though there are two widely-separated zones of these...

The income index compares the average employment income value of each community to that for Canada. The value for Canada as a whole is set at 1.00. The range of the index is from 0.12 to 1.65, with the median value for these communities being 0.73. Income index values are generally higher in...

The education index is a measure of the proportion of the population 15 years of age and over who have post-secondary qualifications compared to the Canadian proportion meeting the same criteria. The index values are generally lower than the Canadian average. The median value is 0.78, and 88% of...

This map shows the distribution of land cover types across Canada, based on satellite data obtained in 1995. The land cover map contains 31 classes: 12 forest; 3 shrubland; 7 tundra/grasslands; 7 developed land types including cropland, mosaic and built-up areas; and 2 water cover types.

The geologic time scale divides the 4.6 billion years of earths history into hierarchy of time periods. Every layer of rock corresponds to a specific time in the history of the formation of the Earth. The Precambrian era began with the formation of the Earth; it was followed by the Paleozoic,...

Rocks are divided into three main categories according to how they were formed: igneous, sedimentary or metamorphic processes. Rocks differ in their texture, mineral and chemical composition, and bedding characteristics depending on which of these three processes that formed them. Igneous rocks,...

Surficial hydrogeological materials show the distribution of sediment deposited in glacially influenced environments. Most drinkable groundwater resources in Canada occur in shallow surficial-sediment aquifers. Surface sediments, such as gravel, sand, silt and clay, or mixed sediments, are an...

Moisture regions illustrate moist (water surplus) and dry (water deficient) climate areas. The regions are a general guide to moisture surplus or deficit to be factored with seasonal timing of moisture availability for the hydrological system, including fluxes to runoff and groundwater infiltration.

This map shows a simplified distribution of land cover types across Canada interpreted from satellite data obtained in 1995. Land cover has an important role in the water cycle as it significantly affects evapotranspiration and the amount of water leaving a watershed. Evapotranspiration is the...

Hydrogeological regions are areas in which the properties of sub-surface water, or groundwater, are broadly similar in geology, climate and topography. Hydrogeology is the branch of geology that deals with the distribution and movement of water beneath the earth’s surface. This map shows Canada’s...

The map shows 3172 hydrometric stations, 1491 active and 1681 inactive, located on rivers and lakes across the country. All the stations on the map are situated in a drainage area of 200 square kilometres or more. For 1200 stations shown on the map, surface water level measurements are recorded...

A drainage basin is an area that drains all precipitation received as a runoff or base flow (groundwater sources) into a particular river or set of rivers. Canada’s major drainage regions are the Atlantic Ocean, Hudson Bay, Arctic Ocean, Pacific Ocean and Gulf of Mexico. Rivers are organized into...

Apart from a source of drinking water, the water resources in watersheds supply water for irrigation and the production of hydroelectricity, and are a primary mode of transportation. Major water consumers are municipalities, agriculture, mining, manufacturing and thermal power generation. The...

The physical components of a watershed are rivers, lakes, ponds and reservoirs, groundwater aquifers, snowpacks, glaciers, ice fields, wetlands and precipitation. This map shows the different hydrological components of a watershed, some physical components that affect watersheds and some...

A watershed is an area that drains all precipitation received as a runoff or base flow (groundwater sources) into a particular river or set of rivers. The easiest way to describe the network of rivers and lakes on a small-scale map is to show the watersheds. In Canada, there is a detailed...

Permafrost occurs when the ground remains at or below a temperature of 0oC for a minimum period of two years. Permafrost occurs not only at high latitudes but also at high altitudes. Almost all of the soil moisture in permafrost occurs in the form of ground ice, which in turn occurs in several...

This map shows the location of the Arctic physiographic regions which include the Innuitian Region, the Arctic Lowlands and the Arctic Coastal Plains.
