A doh mini-on astronomical observatory (Dominion Observatory) is the astronomical observatory which there was in Ottawa, Canada. It was managed as an astronomical observatory from 1902 through 1970. In the facilities of the Canadian federal government, I was established for the management in longitude, a standard of the latitude and the standard. It was said by 1902 what was observed at an observatory of the Ottawa River that real National Astronomical Observatory such as British Royal Greenwich Observatory was necessary, and the establishment was decided till then.

A central experiment farm of the Ministry of Agriculture nearly Dow gap Iku was chosen, and the place of the new astronomical observatory was completed in 1905. The main observation facilities were maximum telescopes at the time of in a reflecting telescope of 15 inches in Canada. The purpose of the astronomical observatory was a standard of management and the land surveying in the standard, but much observation was carried out for the purpose of others. I played a key role of the geophysical study in Canada including the administration of the Canadian seismometry network for a long time. The need of new facilities increased to cope with astrophysical development, and doh mini-on heavenly bodies physics astronomical observatory was built in Victoria in 1917.

The doh mini-on astronomical observatory was managed until the organization of the research institute of Canada was reorganized in 1970. Management and the astronomy observation in the standard were put into national study mechanism (National Research Council: NRC) in Canada, and the earth science, the geological survey, the cartography duties were moved to energy, mine, resources province. The duties of the earth science are unified by a geological survey place in Canada and belong to the Canadian natural resource station now. The management in the standard was abolished by the use of the atomic clock. The building of the doh mini-on astronomical observatory was used as the headquarters of the national study mechanism in Canada. The telescope was opened to the public from 1905 through 1970. The telescope is moved to Helen Sawyer Hogg astronomical observatory of Canadian Museum of Science and Engineering in 1974 and is saved now. As of 2008, a building is the headquarters of the energy consumption efficiency secretariat of the ministry of natural resources.
