Information: - Toronto is the most populous city in Canada, the provincial capital of Ontario, and the centre of the Greater Toronto Area, the most populous metropolitan area in Canada. Growing in population, the 2011 census recorded a population of 2,615,060. As of 2015, the population is now estimated at 2,826,498, making Toronto the fourth-largest city in North America based on the population within its city limits. Toronto trails only Mexico City, New York City, and Los Angeles by this measure, while it is the fifth-largest (behind also Chicago) if ranked by the size of its metropolitan area . An established global city, Toronto is an international centre of business, finance, arts, and culture, and widely recognized as one of the most multicultural and cosmopolitan cities in the world. - Nickel is a chemical element with symbol Ni and atomic number 28. It is a silvery-white lustrous metal with a slight golden tinge. Nickel belongs to the transition metals and is hard and ductile. Pure nickel, powdered to maximize the reactive surface area, shows a significant chemical activity, but larger pieces are slow to react with air under standard conditions because an oxide layer forms on the surface and prevents further corrosion (passivation). Even so, pure native nickel is found in Earth's crust only in tiny amounts, usually in ultramafic rocks, and in the interiors of larger nickeliron meteorites that were not exposed to oxygen when outside Earth's atmosphere. - Hydrogen is a chemical element with chemical symbolH and atomic number1. With an atomic weight of , hydrogen is the lightest element on the periodic table. Its monatomic form (H) is the most abundant chemical substance in the Universe, constituting roughly 75% of all baryonic mass. Non-remnant stars are mainly composed of hydrogen in the plasma state. The most common isotope of hydrogen, termed "protium" (name rarely used, symbol H), has one proton and no neutrons. - Montreal officially Montreal in both Canadian English and French, is the most populous municipality in Quebec and the 2nd-most populous in Canada. Originally called "Ville-Marie", or "City of Mary," it is named after Mount Royal, the triple-peaked hill in the heart of the city. The city is on the Island of Montreal, which took its name from the same source as the city, and a few much smaller peripheral islands, the largest of which is Ile Bizard. It has a distinct four-season continental climate with warm to hot summers and cold snowy winters. - The Rocky Mountains, commonly known as the Rockies, are a major mountain range in western North America. The Rocky Mountains stretch more than from the northernmost part of British Columbia, in western Canada, to New Mexico, in the southwestern United States. Within the North American Cordillera, the Rockies are somewhat distinct from the Pacific Coast Ranges and the Cascade Range and Sierra Nevada which all lie further to the west. - Canada's geography is divided into administrative divisions known as provinces and territories that are responsible for delivery of sub-national governance. When Canada was formed in 1867, three provinces of British North America New Brunswick, Nova Scotia and the Province of Canada (which, on the formation of Canada, was divided into Ontario and Quebec) were united to form a federated colony, which eventually became a sovereign nation in the next century. Over its history, Canada's international borders have changed several times, and the country has grown from the original four provinces to the current ten provinces and three territories. The ten provinces are Alberta, British Columbia, Manitoba, New Brunswick, Newfoundland and Labrador, Nova Scotia, Ontario, Prince Edward Island, Quebec, and Saskatchewan. Several of the provinces were former British colonies, Quebec was originally a French colony, while others were added as Canada grew. The three territories are Northwest Territories, Nunavut, and Yukon, which govern the rest of the area of the former British North America. Together, the provinces and territories make up the world's second-largest country by area. - Ottawa is the capital city of Canada. It stands on the south bank of the Ottawa River in the eastern portion of southern Ontario. Ottawa borders Gatineau, Quebec; the two form the core of the OttawaGatineau census metropolitan area (CMA) and the National Capital Region (NCR). The 2011 census reported a population of 883,391, making it the fourth-largest city in Canada; and 1,236,324 within the CMA, making it the fourth-largest CMA in Canada. The City of Ottawa reported that the city had an estimated population of 960,754 as of December 2015. - Quebec City (pronounced or ) officially Quebec) is the capital city of the Canadian province of Quebec. In 2015 the city had a population estimate of 545,485, and the metropolitan area had a population of 806,400, making it Canada's seventh-largest metropolitan area and Quebec's second-largest city after Montreal, which is about to the southwest. - Greater Sudbury, commonly referred to as Sudbury, is a city in Ontario, Canada. It is the largest city in Northern Ontario by population, (2011 census population 160,274,) and is the 24th largest metropolitan area in Canada. By land area, it is the largest city in Ontario and the seventh largest municipality by area in Canada. It is administratively a single-tier municipality, and thus not part of any district, county, or regional municipality. - Heavy water (deuterium oxide) is a form of water that contains a larger than normal amount of the hydrogen isotope deuterium (or D, also known as "heavy hydrogen"), rather than the common hydrogen-1 isotope (or H, also called protium) that makes up most of the hydrogen in normal water. The presence of deuterium gives the chemical different nuclear properties, and the increase of mass gives it different physical and chemical properties compared to normal "light water". - The Northwest Territories (also known as NWT; French: "les Territoires du Nord-Ouest", "TNO"; Athabaskan languages: "Denendeh"; Inuinnaqtun: "Nunatsiaq"; Inuktitut: ) is a territory of Canada. At a land area of approximately and a 2011 population of 41,462, it is the second largest and most populous of the three territories in Northern Canada. Its estimated population as of 2016 is 44,291. Yellowknife became the territorial capital in 1967, following recommendations by the Carrothers Commission. - Nunavut (from Inuktitut: ) is the newest, largest, northernmost, and least populous territory of Canada. It was separated officially from the Northwest Territories on April 1, 1999, via the Nunavut Act and the Nunavut Land Claims Agreement Act, though the boundaries had been contemplatively drawn in 1993. The creation of Nunavut resulted in the first major change to Canada's political map since the incorporation of the province of Newfoundland and Labrador in 1949. - Deuterium (symbol ' or ', also known as heavy hydrogen) is one of two stable isotopes of hydrogen. The nucleus of deuterium, called a deuteron, contains one proton and one neutron, whereas the far more common hydrogen isotope, protium, has no neutron in the nucleus. Deuterium has a natural abundance in Earth's oceans of about one atom in of hydrogen. Thus deuterium accounts for approximately 0.0156% (or on a mass basis 0.0312%) of all the naturally occurring hydrogen in the oceans, while the most common isotope (hydrogen-1 or protium) accounts for more than 99.98%. The abundance of deuterium changes slightly from one kind of natural water to another (see Vienna Standard Mean Ocean Water). - Edmonton is the capital city of the Canadian province of Alberta. Edmonton is on the North Saskatchewan River and is the centre of the Edmonton Capital Region, which is surrounded by Alberta's central region. - Winnipeg is the capital and largest city of the province of Manitoba in Canada. It is located near the longitudinal centre of North America, at the confluence of the Red and Assiniboine Rivers. - Creighton Mine is an underground nickel mine, owned and operated by Vale (formerly known as INCO) in the city of Greater Sudbury, Ontario, Canada. It is currently the deepest nickel mine in Canada. - FOREST (short for "Freedom Organisation for the Right to Enjoy Smoking Tobacco") is a United Kingdom political pressure group which campaigns against tobacco control activity. - Calgary is a city in the Canadian province of Alberta. It is situated at the confluence of the Bow River and the Elbow River in the south of the province, in an area of foothills and prairie, about east of the front ranges of the Canadian Rockies. In the 2011 census, the City of Calgary had a population of 1,096,833 and a metropolitan population of 1,214,839, making it the largest city in Alberta, and the third-largest municipality and fifth-largest census metropolitan area (CMA) in Canada. - In physical geography, tundra is a type of biome where the tree growth is hindered by low temperatures and short growing seasons. The term "tundra" comes through Russian ("tundra") from the Kildin Sami word "tndar" "uplands", "treeless mountain tract". There are three types of tundra: Arctic tundra, alpine tundra, and Antarctic tundra. In tundra, the vegetation is composed of dwarf shrubs, sedges and grasses, mosses, and lichens. Scattered trees grow in some tundra regions. The ecotone (or ecological boundary region) between the tundra and the forest is known as the tree line or timberline. - Isotopes are variants of a particular chemical element which differ in neutron number. All isotopes of a given element have the same number of protons in each atom. The term isotope is formed from the Greek roots isos ( "equal") and topos ( "place"), meaning "the same place"; thus, the meaning behind the name is that different isotopes of a single element occupy the same position on the periodic table. - Rats are various medium-sized, long-tailed rodents of the superfamily Muroidea. "True rats" are members of the genus "Rattus", the most important of which to humans are the black rat, "Rattus rattus", and the brown rat, "Rattus norvegicus". Many members of other rodent genera and families are also referred to as rats, and share many characteristics with true rats. - The Sudbury Neutrino Observatory ( SNO ) was a neutrino observatory located 2100 m underground in INCO 's Creighton Mine in Sudbury , Ontario , Canada . The detector was designed to detect solar neutrinos through their interactions with a large tank of heavy water . The detector was turned on in May 1999 , and was turned off on 28 November 2006 . The SNO collaboration was active for several years after that analyzing the data taken . The director of the experiment , Art McDonald , was co-awarded the Nobel Prize in Physics in 2015 for the experiment 's contribution to the discovery of neutrino oscillation . The underground laboratory has been enlarged into a permament facility and now operates multiple experiments as SNOLAB . The SNO equipment itself is currently being refurbished for use in the SNO + experiment . - Vancouver, officially the City of Vancouver, is a coastal seaport city on the mainland of British Columbia, Canada, and the most populous city in the province. - Canada (French: ) is a country in the northern half of North America. Its ten provinces and three territories extend from the Atlantic to the Pacific and northward into the Arctic Ocean, covering , making it the world's second-largest country by total area and the fourth-largest country by land area. Canada's border with the United States is the world's longest land border. The majority of the country has a cold or severely cold winter climate, but southerly areas are warm in summer. Canada is sparsely populated, the majority of its land territory being dominated by forest and tundra and the Rocky Mountains. About four-fifths of the country's population of 36 million people is urbanized and live near the southern border. Its capital is Ottawa, its largest city is Toronto; other major urban areas include Montreal, Vancouver, Calgary, Edmonton, Quebec City, Winnipeg and Hamilton. - Ontario, one of the 13 provinces and territories of Canada, is located in east-central Canada. It is Canada's most populous province by a large margin, accounting for nearly 40 percent of all Canadians, and is the second-largest province in total area. Ontario is fourth-largest in total area when the territories of the Northwest Territories and Nunavut are included. It is home to the nation's capital city, Ottawa, and the nation's most populous city, Toronto.
