The Warner elevator row is a group of four historic wood-cribbed grain elevators standing in a row from south to north alongside the Canadian Pacific Railway line from Great Falls, Montana to Lethbridge, Alberta at the east entrance of the village of Warner, Alberta, Canada.

[5] The structure and history of each elevator was influenced by developments in the grain industry and its companies from before World War II to the 1980s.

A small number of late-1930s elevators remain in Alberta, a reminder that few were built for some time after 1934.

The United Grain Growers elevator and annex were built between 1957 and 1960, and the complex was licensed for 134,000 imperial bushels (4,900 m3) in 1960.

The elevator was upgraded during the late 1980s, including the installation of a new leg which required raising part of the cupola; the metal bin annexes on the south side and drag auger date from that time.

A cyclone dust collector and truck-loading spout have been installed, and a roofed track-side warehouse on the north side was probably built at the same time as the elevator.

Before its demolition, it was one of the two oldest examples of standard Alberta Farmers' Elevator Company 1913–1917 design.

In 1917 the companies merged to form the United Grain Growers, headquartered in Winnipeg, Manitoba.

In 1940 a 35,000-imperial-bushel (1,300 m3) balloon annex, built by the F. W. McDougall Construction Company, was added to the elevator and later removed.

It measured 34 × 35 × 62 feet (10 × 11 × 19 m); a balloon annex built on the south side in 1940 was removed in 1995.

The 1968 65,000-imperial-bushel (2,400 m3) Federal Grain elevator measures 38 × 44 × 66 feet (12 × 13 × 20 m), with an electronic scale and an exterior loading spout for trucks.
