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

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.
