Yellowjacket

Yellowjacket is the common name for wasps in the genera Vespula and Dolichovespula. They belong to the insect family Vespidae in the order Hymenoptera, which also includes other types of wasps such as hornets, as well as bees and ants. Worldwide, there are about 50 recognized species of yellowjacket, 17 of which are native to Canada. These native species include the common (Vespula alascensis), Eastern (V. maculifrons), Western (V. pensylvanica) and aerial (Dolichovespula arenaria) yellowjacket. One species, the German yellowjacket (V. germanica), is introduced to Canada and is especially common in Ontario and Quebec.

Whale Species in Canada

Whale is the common name for large marine mammals of the order Cetartiodactyla (formerly Cetacea). They are subdivided into the Mysticeti, or baleen whales, and Odontoceti, or toothed whales. Smaller kinds of toothed whales are called dolphins or porpoises. Thirty-five whale species are found at least occasionally in Canadian waters — 9 species of baleen whales, and 26 species of toothed whales (mostly dolphins and porpoises). The commercial pursuit of whales was significant in early European exploration of Canada (see Whaling). Since the end of commercial whaling in Canada in 1972, whale watching has become popular. Whales found in Canada range in size from about 60 kg for the harbour porpoise to well over 100 tonnes for the blue whale, making it the largest animal ever known.

Water

Worldwide, over two-thirds of precipitation falling on land surfaces is evaporated and transpired back into the atmosphere. In Canada less than 40% is evaporated and transpired; the remainder, called the water yield, enters into streamflow.

Hurricane Hazel

Hurricane Hazel struck the Toronto area on 15-16 October 1954, with devastating results. It was Canada's worst hurricane and Toronto's worst natural disaster. During the storm, winds reached 124 km/h and over 200 millimetres of rain fell in just 24 hours. This horrific storm left 81 dead, nearly 1900 families homeless, and caused between $25 and $100 million in damages (modern-day cost has been estimated at over $1 billion).

Rupert's Land

Rupert’s Land was a vast territory of northern wilderness. It represented a third of what is now Canada. From 1670 to 1870, it was the exclusive commercial domain of the Hudson’s Bay Company(HBC) and the primary trapping grounds of the fur trade. The territory was named after Prince Rupert, the HBC’s first governor. Three years after Confederation, the Government of Canada acquired Rupert’s Land from the HBC for CAD$1.5-million (£300,000). It is the largest real estate transaction (by land area) in the country’s history. The purchase of Rupert’s Land transformed Canada geographically. It changed from a modest country in the northeast of the continent into an expansive one that reached across North America. Rupert’s Land was eventually divided among Quebec, Ontario, Manitoba, Saskatchewan, Albertaand the Northwest Territories.

North-West Territories (1870–1905)

The North-West Territories was the first Canadian territory. It was Established on 15 July 1870. As a territory, the region became part of Canada. But it lacked the population, economic and infrastructure resources to attain provincial status. It thus fell under the jurisdiction of the federal government. It covered a vast area, stretching west from a disputed boundary with Labrador, across the northern portions of present-day Quebec and Ontario, through the Prairies to British Columbia, and north from the 49th parallel to the Arctic Ocean. The territory was subject to numerous boundary changes before 1905. At that time, the provinces of Saskatchewan and Alberta were carved out of the southwest portion of the region. In 1906, the remaining territory was renamed the Northwest Territories.

Snake Species in Canada

A snake is a long, slender reptile of the suborder Serpentes, within the order Squamata (which also includes lizards). There are 25 species of snake currently found in Canada. In addition, one species, the timber rattlesnake, and one subspecies, the Pacific gophersnake, are extirpated. This means that, while they continue to live in other parts of their range, they are no longer found in Canada. Snake species in Canada belong to one of three taxonomic families: Boidae, Viperidae or Colubridae. Most species live in the southern part of the country; however, the common gartersnake can be found as far north as the 60th parallel, near Fort Smith, Northwest Territories.

Common Gartersnake

The common gartersnake (Thamnophis sirtalis) is a relatively small, striped, non-venomous snake. It is one of the most widespread snake species in North America and its range extends farther north than any other North American snake. In Canada, it is found in every province except Newfoundland and Labrador, and as far north as James Bay and into the southernmost Northwest Territories. The common gartersnake is broken into five subspecies across Canada: the Maritime gartersnake (Thamnophis s. pallidulus; PEI, NS, NB, QC), the Eastern gartersnake (Thamnophis s. sirtalis; QC, ON), the red-sided gartersnake (Thamnophis s. parietalis; ON, MB, SK, AB, BC, NWT), the valley gartersnake (Thamnophis s. fitchi; BC), and the Puget Sound gartersnake (Thamnophis s. pickeringii; BC).

Physiographic Regions

Canada may be divided into seven physiographic regions. The Canadian Shield is the largest and oldest of these regions. The other six physiographic regions are younger and form two concentric rings around the Canadian Shield. The outer, older ring contains the Western Cordillera, Canadian Arctic and Appalachian Region. The second, younger ring contains the Interior Plains, Hudson Bay Lowlands and the St. Lawrence Lowlands. These regions may be further sub-divided based on their structure, relief and the presence or absence of permafrost and forest cover (see Natural Regions).

Areas quoted for these regions are the land areas and do not include adjacent continental shelves or bodies of ocean water within Canada's territorial limits. Readers should also note that the abbreviation “masl” stands for “metres above sea level.”

Rocky Mountain Trench

The Rocky Mountain Trench is a long and deep valley extending approximately 1,500 km from the Bitterroot Valley in northwest Montana through British Columbia to the Liard Plain just south of the Yukon Territory. Its predominantly flat floor is 3–20 km wide and ranges in elevation between 600 m and 1,000 m above sea level. With walls made of sedimentary, volcanic and igneous rock, the Trench is sometimes referred to as the “Valley of a Thousand Peaks” because of the towering mountain ranges on either side: the Rocky Mountains to the east and the Columbia, Omineca and Cassiar mountains to the west. Humans have relied on the rich resources provided by this distinctive landscape from pre-colonial times to the present.

Reserves in Saskatchewan

Saskatchewan is home to at least 70 First Nations and various Métis communities. It contains 782 reserves, settlements and villages, many of which are located in the southern half of the province. Reserves in Saskatchewan were created between 1874 and 1906 by Treaties 2, 4, 5, 6, 8 and 10. As of 2016, 47.5 per cent of the province’s 114,570 self-identified First Nations peoples live on reserves, a percentage comparable to the province of Manitoba. Most of the remaining 47 per cent who reside off-reserve in Saskatchewan live in the cities of Saskatoon, Regina and Prince Albert.

National Parks of Canada

Canada’s national parks are protected areas established under federal legislation to preserve Canada’s natural heritage. They are administered by Parks Canada, a government agency that evolved from the world’s first national parks service, the Dominion Parks Branch, established in 1911. The National Parks System Plan, developed in 1970, divided Canada into 39 natural regions and set the goal of representing each region with at least one national park. Canada now has 48 national parks and national park reserves in 30 of these regions. In total, the parks cover more than 340,000 km2, which is over 3 per cent of Canada’s landmass. They protect important land and marine habitats, geographical features and sites of cultural significance. National parks also benefit local economies and the tourism industry in Canada.

Toad Species in Canada

Toad is a common name for frogs belonging to the family Bufonidae. The distinction is not firm, but the word toad is generally applied to frogs with relatively short legs and thick bodies, dry, often “warty” skin and reduced webbing between the toes. Five toad species are found in Canada, living in drier habitats than most other frogs. In Canada, other frogs commonly called toads are the Plains and Great Basin spadefoots (family Scaphiopodidae). For more general information about frogs (including toads) see Frog Species in Canada.

Agriculture in Canada

Agriculture is the practice of growing crops and rearing animals mainly for food. Farmers also produce other items such as wool from sheep and CBD oil from hemp plants.

In Canada, agriculture is an important industry. Only about 7 per cent of Canada’s land can be farmed. Other marginal (poorer) land can be used to ranch cattle. Aquaculture operations are found on the East and West Coasts and in the Great Lakes. Some crops such as tomatoes, cannabis and flowers are grown in greenhouses in urban centres. Canadian agriculture faces many challenges. Some of these challenges concern crop protection, soil conservation, labour, climate change and health.
