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...

In Canada, there are 20 ecozones, consisting of 15 terrestrial and 5 marine units. The vegetation varies from one ecozone to another. Forests cover totally or partially nine ecozones: Pacific Maritime, Montane Cordillera, Boreal Cordillera, Taiga Plains, Boreal Plains, Prairie, Boreal Shield,...

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.

Nine zones indicate the areas where various trees, shrubs and flowers are most likely to survive. These zones are calculated based on average climatic conditions and altitude of each area. The harshest zone is 0 and the mildest is 8. Each major zone is divided into subzones a and b (for example...

Ecozones are broad ecological zones on the earth's surface and cover a large range of ecosystems such as temperate forest, mountain ranges, grassland, taiga, arctic tundra, extensive river systems, coastline and farmlands. Each ecozone has its own climate, relief, soil, fauna and flora and...

This map shows the number of tree species by ecoregion.There are about 180 species of trees in Canada. More tree species are found in Southern Ontario and along the St. Lawrence River. The highest number of tree species is found in the Lake Erie Lowlands ecoregion.

Wetlands are areas characterized by relatively shallow water. These areas play an extremely important role in Canada's ecology. Canada has one of the largest areas in the world with wetlands covering more than 1.2 million square kilometres. They occur across most of the country, and their...

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...

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...
