The name for Gourley Park was taken from a man named Colonel William Gourlay (1794-1867), a farmer and part-time soldier who fought in the Rebellion of 1837. The neighbourhood where his farm was located was named after him, even though it was spelled with an "e" instead of an "a". On July 29, 1975, the Board of Education traded Gourley Park for some land from the City.
Gourley Park was also the location of a very special birthday party on July 1, 1991, as Hamiltonians gathered to celebrate Canada Day. Festivities included a "media" baseball game, featuring local radio and television personalities, as well as, face painting, a treasure hunt, games, races and lots of hot dogs!
In 1992 approval was given for some improvements to the park, including the installation of two tennis courts and some fencing.
