The first known name for the area was Third Crossing, as it was situated at the third crossing of a prairie trail over the Whitemud River. When settlement became significant in 1872 the community was renamed to Palestine.[1]
In 1879, the community was renamed a third and final time to Gladstone, after the British Prime Minister of the time William Ewart Gladstone. On 18 July 1882, the community was incorporated as the Town of Gladstone.[1]
In the 2021 Census of Population conducted by Statistics Canada, Gladstone had a population of 928 living in 407 of its 443 total private dwellings, a change of 4.4% from its 2016 population of 889. With a land area of 2.39 km2 (0.92 sq mi), it had a population density of 388.3/km2 (1,005.7/sq mi) in 2021.[3]
Gladstone is often referred to as "Happy Rock", a play on the community's name: "happy" being another word for "glad", and "rock being another word for "stone".[4][1]
This is the name given to the community's monument located along Highway 16, acting as the symbol and mascot of the community. The Happy Rock monument also acts as the visitor information centre and is a vital part of tourism in the community. On July 5, 2010, Canada Post made a commemorative stamp of the Happy Rock as part of its Roadside Attractions collection.[5]
