Grand Valley was located on the northern side of the Assiniboine, opposite the side of the river where present-day Brandon sits.
Grand Valley was originally settled by two brothers John and Dougal Mc Vicar, and their families.
During the 1870s it was believed by most that the transcontinental railway would take a northwesterly direction from Portage la Prairie.
Many thought that the route would most likely go through either Minnedosa or Rapid City, Manitoba because they were both located at natural river crossings.
