National Observatory was cancelled on August 29, 1968. The unfinished 150-inch mirror for the Queen Elizabeth II Telescope was stored until sold in 1986. It is believed that the mirror blank was melted down and recycled. The 16-inch telescope remained on the site until 1981, when it

The criteria for the selection of an observatory site were several. The site had to have an elevation of at least 4,000 feet (1,200 m) (in order to keep atmospheric turbulence to a minimum), not be subject to rapid changes in weather or extreme temperature, and be distant from industrial and

Canadian astronomical community grew, as it was felt by some that a site of much higher quality could be obtained outside of Canada.

proposed the construction of a national observatory, with a 3.81 m (150 inch) telescope as the primary instrument. Upon completion, this would have been the second largest telescope in the world, the only larger telescope being the 5.08 m (200 inch)
