Paul Kalmring's family ran a corner store and gas station for most of the time between 1916 and 1983 in the tiny community, named after federal senators of the day when the community was created in 1914. Kalmring's family moved to the area when Paul was two, and his father soon purchased a convenience store and gas station.

Senate's population peaked at 63 in the 1940s and was a stopping point for the Canadian Pacific Railway. For a few years, Senate even had its own train ticket agent.

The west had just been opened up to waves of European settlers seeking prosperity, and at first, the future appeared promising for Senate and several others along Highway 13.

During Senate's best years, the community had two elevators, a five-room hotel and restaurant, blacksmith shop, lumberyard and Kalmring's general store and gas station. For leisure, the citizens of Senate also built a tennis court and a baseball diamond across the train tracks.

But as in most other locales along southwest Saskatchewan, Senate's fortunes declined after the 1940s. Regional farm consolidation, drought and rural depopulation ended all hope for any lasting life at Senate.

By the early 1980s, Kalmring sold his store and moved to his farm, three kilometres north of Senate. And by 1983, the community was empty. In 1994, with the railway and elevators also gone, rural municipality officials brought in the bulldozers and levelled Senate's remaining dilapidated buildings and dumped part of the debris into a nearby landfill.

Most cities in Canada and throughout the world have their antipodes in the ocean. In the 1940s, Senate was one of only a handful of communities in Canada that has not only land, but a similar size village, in this case Port-aux-Français on the Kerguelen Islands, within 10 kilometres (6.2 mi) of its antipode.

Prior to January 1, 1994, Senate was incorporated as a village, and was dissolved into an unincorporated community under the jurisdiction of the Rural municipality of Reno on that date.
