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,

Located on 4 square kilometres (1.5 sq mi) of land, the farm is a National Historic Site of Canada and most buildings are protected and preserved as heritage buildings. The CEF's original intent was to perform scientific research for improvement in agricultural methods and crops. While such research is still being conducted, the park-like atmosphere of

288-475: The Minister of Agriculture, and William Saunders , the first director of the research branch, the "Act Respecting Experimental Stations" came into force in 1886. The land owned by local Ottawa farmers including John Mulligan (1799–1886) was sold to the government to create the experimental farm. The CEF started out with 188 hectares, chosen because of their proximity to Parliament Hill but (at that time) outside

312-822: The city. Over the next few years the site was prepared by improving the land, building the facilities, and planting the Arboretum and forest belt. Early research projects focused only on entomology , botany , and horticulture .
