Salmon! At spawning time, one could fairly walk across the Credit here on the backs of spawning Atlantic Salmon. So said the pioneers in Esquesing and Chingacousy Townships. But as the wilderness was tamed, the salmon eventually disappeared. History first records this area, Terra Cotta, as Tucker’s Mill.
Joseph Kenny and John McCombs were the first to settle here in 1822.
In 1855, Henry Tucker bought 40 acres and built the first mill here.
In 1855, Henry Tucker purchased 40 acres of the East half of Lot 27, Concession 6 West, for 800 dollars. He hired a surveyor to lay out 18 village lots. Tucker sold his prosperous holdings in 1859 to Simon Plewes, a Yorkshire miller who had run the mill at Acton with his father and brother from 1850. In 1863, he married Janet Smith, an Esquesing girl. Together they had six children. Unfortunately, Simon drowned in his mill race in 1876 at the age of 45.
The future of Plewes’ Mills seemed certain in 1863 when the Wesleyan Methodists opened their church here, putting it on the Georgetown circuit. Before that, the nearest church was Union Presbyterian on lot 23, Esquesing. They built the first log church in 1835. The present stately stone church was erected in 1883 with stone from Townsend’s quarry.
In 1866, the post office opened as Salmonville.
William Watkins was the first postmaster and moved to Glen Williams the following year. A general store and post office have served the village since then. James Carol was postmaster in 1871 and still held the post in 1891 when the name was changed to Terra Cotta. He was followed by Jane Smith in 1894. She built a new store in 1899, which still serves the village today.
In 1891, the village post office was renamed Terra Cotta after the red clay suitable for firing pottery.
A good education was important to the pioneering families in this area, and school sections were established in 1842.
Chinguacousy Township School Section #3 served this corner of Peel County, while Esquesing Township School Section #15, or Clay Hill School, served Halton County youngsters. SS#3 was located on the 5th Line West at 22 Sideroad. It closed in 1960 and is now a private home. Creditview Public School on Mississauga Road opened in 1964. Clay Hill School was at Lot 29 on the 10th Line, Esquitesing. It closed about 1959 and later burned down.
The sequence of names was roughly as follows:
Tucker’s Mill / Tucker’s Mills (from 1855) — after Henry Tucker, who built the first mill here.
Plewes Mills (from about 1859) — after Simon Plewes, who bought the mill.
Salmonville (from the opening of the post office in 1866) — after the abundance of Atlantic salmon in the Credit River. Pioneers said that at spawning time you could walk across the river on the backs of the fish, and that the salmon could be taken with a pitchfork.
Terra Cotta (post office renamed in 1891) — after the red clay and the brickworks (“terra cotta” = baked earth).

An important step for Terra Cotta was the building of the Hamilton and North Western Railway just north of the village in 1877.
The railway helped move limestone and sandstone quarried in this area from the 1850s. The Townsend family, in particular, ran the principal quarries in the 19th century. Quarries flourished on the 5th and 6th Lines in Chinguacousy and also on the 9th and 10th Lines in Esquites. Credit Valley stone became known for its quality all across the country.
The Village was doing a steady business in stone by the turn of the century.
The quarries of Jack Murray (successor of the Townshends) installed an incline railway up the escarpment in 1904. J. L. Dolson opened a new quarry the previous year.
While the stone of the escarpment was quarried above the village, the very shale on which it sat attracted the brick-making business in 1906. The Terra Cotta Pressed Brick Co. commenced operations on a large scale. An electric power house was erected where Mr. Plewes’ grist mill stood, and the power was transmitted to the brick plant near the train station. This created many jobs. In 1911, Elijah Townsend sold land to William Flavelle and Robert Kennedy to form the Halton Brick Company.
A third brick factory was opened on 27th Sideroad, Esquesing, in 1914 by L. Plant.
All three plants boomed until the Depression of 1929 began. They were closed and eventually dismantled.
A fire destroyed the CNR train station in 1956, marking the end of Terra Cotta’s industrial age. This lack of industry began Terra Cotta’s next period of growth.
The tourist focus began in 1944, when Toronto artist Jordanus Vander Vliet purchased land for a home and art studio, where he started classes and attracted artists from across the province.
John Agg succeeded him, and in 1959 Rebecca Sisler renovated the former blacksmith shop into the Forge studio.

Summer cottages led Rod Clancy to lay out a summer park which eventually became the Terra Cotta Conservation Area in 1958. The Credit Valley Conservation Authority runs this very successful attraction.
Betty and Harry Farrar purchased a riverside property in 1951 and created the Terra Cotta Inn. A hotel had once operated on the same site. This business alone soon attracted many tourists to the Village. A 1975 fire did not stop the Inn for long; the owners rebuilt and expanded. The 1989 recession also closed the business, but it reopened in 1994.
The Region of Peel purchased the Forge in 1969 to straighten the road. The local opposition was most vocal! The Village’s charm was preserved. The Region of Peel now makes the historic Forge available for art shows.
Peel Region also recognized the Terra Cotta Community Hall as a historic site in 1992.
Trustees maintained the former Methodist Church with help from the Thursday Thimble Club from 1949. This club has also helped with street lighting, welcome signs and funds for the Georgetown Hospital.
The Terra Cotta Women’s Institute, formed in 1931, has documented this history and the Village’s changes. They also helped the Terra Cotta Farmers’ Club (1913-1976) to buy the former SS#3 as a hall in 1961. They sold it and renovated it into a home in 1971.
Nature’s blessings have always stood Terra Cotta in good stead. Abundant salmon, thick limestone deposits, rich, deep clay, and a winding river with bountiful flora and fauna have provided a living for many through the years. Today, salmon return, reintroduced in 1988. The story of this verdant valley is far from over!
