9 O'Clock Gun
The 9 O'Clock Gun is a cannon located in Vancouver, British Columbia that is shot every night at 21:00 (9 p.m.) PT. The gun is a 12-pound muzzle-loaded naval cannon, cast in Woolwich, England in 1816. Seventy-eight years later, in about 1894, it was brought to Stanley Park by the Department of Marine and Fisheries to warn fishermen of the 18:00 Sunday close of fishing. On October 15, 1898 the gun was fired for the first time in Stanley Park at noon.
The 21:00 firing was later established as a time signal for the general population and to allow the chronometers of ships in port to be accurately set. The Brockton Point lighthouse keeper, William D. Jones, originally detonated a stick of dynamite over the water until the cannon was installed. The cannon is now activated automatically with an electronic trigger which was installed by the Parks Board electrical department. It is still loaded daily with a black powder charge. The fluorescent lights illuminating the gun from overhead go out exactly ten seconds before it fires, and turn back on a few seconds afterward.
