In the 1800s, the region that would become Saint-Alphonse-de-Granby was
colonized, but it would not known by that name until 1890. A
one-room school was inaugurated on a land held by Georges D. Fuller in 1950 to educate the children of the area. In about 1855,
Hungerford Mills, a
sawmill, was constructed by Stephen Léonard Hungerford before it was sold to Joseph B. Hungerford, an American relative, who operated it for 15 years, until Thomas Ferguson took over; the mill was part of the Township of Granby. Another
mill (for flour) appeared before 1870, and it was around these two mills that the village of Saint-Alphonse slowly developed. Houses began to be built; the space was divided in four zones and many workers were hired to run roads across its territory. Many of the workmen who built Saint-Alphonse also worked for the township of Granby. The
parish of Saint-Alphonse was decreed by
Bishop Charles La Rocque of the
Diocese of Saint-Hyacinthe, February 6, 1875. At the request of citizens from the area that a
parson was present on Sundays for
Mass.
Abbot Charbonneau became the parson of Adamsville and Saint-Alphonse and lived three months under a locals roof while his
clergy house near the church, which would be expanded in 1881. On December 30, 1890, the municipality of Saint-Alphonse became a distinct and independent municipality after a petition by the residents of the Saint-Alphonse du Canton de Granby parish. It was in the town's school that the first
municipal council was elected on March 16, 1891, with six councillors and a
mayor. Before the construction of the town hall in 1985, the council rented a room in the town school to hold its sessions. The town's church was hit by
lightning in 1897 and a fire began while the parson was Pierre A. Saint-Pierre. He limited damages with the help of twelve parishioners; and decided not to save the statue of
Saint Anne on its altar. Although the fire left traces, the church was not entirely demolished.
Bishop Moreau wrote in a letter that Saint Anne saved the building. Around 1905, the town grew around a
railroad and a
train station (built by Onéisme Boisvert on rang Saint-Georges, the three floors having a
general store, hotel, and the living quarters of the owner's family. Farmers brought their
livestock on foot and got them on
railroad cars. Local merchandise such as milk and lumber were all transported by train to be sold in
Montreal. Later, the station was sold and moved and also served as a
warehouse for products that arrived or left the town. Between 1925 and 1929, bridges were restored in Saint-Alphonse, and the municipal council constructed a new bridge on 6e rang. Improvements were brought to the bridges on 3e rang (now rang Parent) and the town's bridge (a central pillar was added). In the 1940s,
Maurice Duplessis, the
premier of Quebec implemented
rural electrification, a teamwork of electricity co-operatives of
Roxton Pond,
Sainte-Cécile-de-Milton, Ange-Gardien, Saint-Alphonse, and
Saint-Valérien implemented the project in the region. The co-ops created the ''Coopérative d'électricité de Saint-Valérien de Shefford
, inaugurated in 1947, instead of competing. An airport was established on the land had belonged to Albert Lecours; it is sold to Granby three years later. It ceased with the arrival of Autoroute des Cantons'', in 1962. A new general store, which sold fresh meat, was opened in 1951, when Omer Bédard bought a three-floor building in the heart of the village. It was a popular place and provided access to all essential household items. It also had three apartments by 1957. In 1963, the municipal council received the preliminary plans to
Route 139, which would link the municipality to the highway at exit 38 (now 68), with a
toll booth; construction lasted two years. The toll booth was converted after the tolls abolition in 1988; it was transformed in ''La maison du tourisme de l'Estrie''. The town hall was finally opened in 1986 at the intersection of Rue Principale and Route 139; the first public session was held in the new building that year May 16. ==Demographics==
