The Dominion Arboretum (French: Arboretum du Dominion) is an arboretum part of the Central Experimental Farm of Agriculture and Agri-Food Canada in Ottawa, Ontario, Canada. Originally begun in 1889, the Arboretum covers about 26 hectares (64 acres) of rolling land between Prince of Wales Drive, Dow's Lake and the Rideau Canal. Carleton University is located at the opposite side of the Canal. At a latitude of 45°, it can experience extremely hot and humid summers and extremely cold winters. It displays a wide range of well-established trees and shrubs with the intention of evaluating their hardiness, including 1,700 different species and varieties. The arboretum is open from dawn to dusk and the admission is free. Although the climate of the Ottawa area is Zone 5a, the topography of the Arboretum produces a microclimate and is warmer by one zone. This has allowed for a collection of magnolias, azaleas, and several other fringe trees including Metasequoia and Liriodendron. One of the favourite attractions for tourists is the Ornamental Gardens. In this area are located the annual plant display, perennial borders, lilac walks, roses and hedges. The hedge collection was planted between 1966 and 1968 and contains a variety of species suitable for use as a hedge.

Carleton University
Carleton University

Carleton University is an English-language public research university in Ottawa, Ontario, Canada. Founded in 1942 as Carleton College, the institution originally operated as a private, non-denominational evening college to serve returning World War II veterans. Carleton was chartered as a university by the provincial government in 1952 through The Carleton University Act, which was then amended in 1957, giving the institution its current name. The university is named for the now-dissolved Carleton County, which included the city of Ottawa at the time the university was founded. Carleton County, in turn, was named in honour of Guy Carleton, 1st Baron Dorchester, who was Governor General of The Canadas from 1786 to 1796. The university moved to its current campus in 1959, growing rapidly in size during the 1960s as the Ontario government increased support for post-secondary institutions and expanded access to higher education. Carleton offers a diverse range of academic programs, and is organized into six faculties and more than 65 degree programs. It has several specialized institutions well-regarded in their fields, including the Arthur Kroeger College of Public Affairs, the Norman Paterson School of International Affairs, the Carleton School of Journalism, the School of Public Policy and Administration, and the Sprott School of Business. As of 2021, Carleton yearly enrolls more than 27,000 undergraduate and 4,000 graduate students. Carleton has a 150-acre campus located west of Old Ottawa South, close to The Glebe and Confederation Heights. It is bounded to the North by the Rideau Canal and Dow's Lake and to the South by the Rideau River. Carleton has more than 165,000 alumni worldwide, producing 7 Rhodes Scholars, 2 Pulitzer Prize awardees, 8 Killam Prize winners, and several recipients of the Order of Canada. Additionally, the university is affiliated with 53 Royal Society Fellows and members and 3 Nobel laureates. Carleton is also home to 28 Canada Research Chairs, 1 Canada 150 Chair, 13 IEEE Fellows and 10 3M National Teaching Award winners.Carleton competes in the U Sports league as the Carleton Ravens. The Carleton Ravens are nationally renowned for their men's basketball team; a team which has won 16 of 19 national championships since 2003.

Dominion Observatory
Dominion Observatory

The Dominion Observatory was an astronomical observatory in Ottawa, Ontario that operated from 1902 to 1970. The Observatory was also an institution within the Canadian Federal Government. The observatory grew out of the Department of the Interior's need for the precise coordinates and timekeeping that at that time could only come from an observatory. For several years they had used a small observatory on the Ottawa River for this purpose. In 1902, it was decided that Canada needed a larger national observatory similar to the Royal Greenwich Observatory in Britain. Chief Dominion Architect David Ewart designed the Dominion Observatory in 1902.The new building was then erected near Dow's Lake on the Agriculture Department's Central Experimental Farm land. This Romanesque Revival building was completed in 1905. Its main instrument was a 15-inch refracting telescope, the largest refracting telescope ever installed in Canada, although it was not a particularly large telescope for this period. While the building and institution were primarily dedicated to astronomical timekeeping in support of surveying, a number of other activities took place here. The Dominion Observatory was Canada's leading institution in Geophysics for many decades, which included the operation of Canada's national seismometer network. The facility did important work, but with this bridgehead into the world of astronomy and the growth of the field of astrophysics, Canadian astronomers quickly demanded a facility designed for the new scientific age. In 1917, the Dominion Astrophysical Observatory was opened in Victoria, B.C. and it supplanted the Dominion Observatory as Canada's foremost astronomical observatory. For many years, the Dominion Observatory was best known to Canadians as the source of Canada's official time signal. The observatory continued in operation until 1970 at which time Canada's science institutions were reorganized. The national time-keeping and astronomical activities were transferred to the National Research Council of Canada, while the geophysics, surveying and mapping were transferred to the Department of Energy Mines and Resources. The Geophysics work was later merged into the Geological Survey of Canada, now part of Natural Resources Canada. Astronomical timekeeping observations at the Dominion Observatory had ceased many years prior to this, when crystal oscillator clocks and, later, atomic clocks were found to be superior to astronomical timekeeping. The building became home to NRCan offices. The telescope had been open for public viewing from 1905 until 1970. In 1974, the telescope was moved from the Dominion Observatory to the Helen Sawyer Hogg Observatory at the Canada Science and Technology Museum where it remained until 2016.As of 2008, the building is the home to the Office of Energy Efficiency, a part of the Energy Branch, Natural Resources Canada.
