Dominion Observatory

[1] The new building was then erected near Dow's Lake on the Agriculture Department's Central Experimental Farm land.

While the building and institution were primarily dedicated to astronomical timekeeping in support of surveying, a number of other activities took place here.

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.

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.
