Description du lieu patrimonial

The Alberta Government Telephones Exchange Building in Mannville is a one-storey, brick-clad building with a hipped roof, wide eaves, and exposed rafters. The main part of the building was constructed in 1917. The hipped roof and rear kitchen extension were added in the 1920s and modern bathroom facilities were added in 1954. In 1965, a modern telephone exchange building was constructed behind the 1917 structure. This newer building is not included in the designation. The Alberta Government Telephones Exchange Building occupies the western portion of a subdivided lot on the corner of 50th Street and 51st Avenue in the Village of Mannville's main commercial district.

Valeur patrimoniale

The heritage value of Mannville's Alberta Government Telephones Exchange Building lies in its association with the expansion of telephone service into rural Alberta and the role played by mutual telephone companies. It is also a significant example of telephone exchange buildings built to an evolving standardized plan.

Telephones were introduced in Alberta in 1885 and began to spread across the province after the Bell Telephone Company established itself in Calgary in 1887. Bell refused to extend services to rural areas believing them to be unprofitable. Consequently, the provincial government began to build rural telephone lines in 1907 and, in the following year, took over Bell's provincial infrastructure to establish a department that would become Alberta Government Telephones (AGT). Later in 1908, a telephone line was extended to Mannville and a switchboard was set-up in a local drug store. In 1917, a stand-alone telephone exchange was built to meet the growing demand for telephone service. It was operated by the government until 1934 when it was turned over to local mutual telephone companies (MTCs). These co-operative organizations, under which local residents built local telephone networks connected to the main government network, were created in 1915 to both reduce government expenses and to hasten the process of extending service into rural areas. During the 1930s, AGT had difficulty maintaining its infrastructure due to falling revenues exacerbated by unpaid bills. The agency began divesting itself of its rural networks by handing them over to the MTCs. By the end of 1936, 600 MTCs had been formed, which increased to over 1,000 by the early 1960s. In 1934 and 1935, five Mannville-based MTCs were formed; two others followed in the early 1960s. By the late 1960s it was realized that the MTCs could not afford to implement new automatic dialling technology and they were ultimately amalgamated back into the AGT network. The first to do so were in the Mannville area. As part of that process, this exchange building was replaced with a more modern facility, which was built on the same lot (now subdivided), immediately to the rear of the old exchange.

Built in 1917, the Alberta Government Telephones Exchange Building in Mannville is an excellent example of a standardized plan used by the Crown corporation. Standardized plans were popular as they allowed for consistency in construction and cost-savings as materials could be made-to-order in bulk. Telephone exchanges of this same relatively simple plan - one-storey, brick-clad buildings with two bays - were constructed in numerous communities of similar size across Alberta, including Bashaw, Carstairs, Cochrane and Innisfail. The front bay was a public area and housed a pay telephone, service counter and the telephone switchboard. Customers gained access through the asymmetrically placed front door. The rear bay was used as living quarters for the telephone agent. These buildings originally had a flat roof with a parapet, giving them a distinctly industrial look. This design was likely adopted by AGT to foster a business-like image befitting an important public utility. In the 1920s, AGT changed its architectural preferences and adopted a more domestic image, possibly as a way of integrating their services and agents into the everyday life of the communities they served. AGT also sponsored beautification contests and frequently funded employee-initiated landscaping and gardening activities around telephone buildings. In 1927, as part of this image change process, the Mannville exchange's flat roof was replaced by a hipped roof with exposed eaves and a wooden canopy was installed over the main door. Similar changes had already been made to the other exchanges of the same standard plan.
