The observatory's original purpose was precise timekeeping and measurement of geographical co-ordinates to assist surveying. Eventually, astronomy, astrophysics and seismography were added to the mandate of the observatory.

In addition to the 15-inch refracting telescope, the observatory included a transit telescope (to measure precise longitude) and coelostat (to study the Sun).

After the observatory was retired, the 15-inch telescope was moved in 1974 to the campus of the Canadian Museum of Science and Technology where the telescope continues to be used at the Helen Sawyer Hogg Observatory.
