This impressive site began back in 1820 when Charles Haines, a millwright from Cheltenham, England emigrated to the area. A year later he built himself a small settlement and in 1848 gave it the name of Cheltenham. In 1827 he added a grist mill.
The area was rich in "medina shale" which was a hard clay that made excellent bricks when fired in kilns.
By 1848 two distilleries were in operation producing liquor such as Cheltenham Wheat Whiskey. Five years later the town could boast not one but three hotels: Henry's, The North American and The Saville (operated by John Saville).
A decade later the town could boast having a mill, three hotels, two general stores, four shoe makers, a tailor, a dress maker and milliner.
In 1866 the town consisted of three mills, trunk and saddle maker, a stove dealer, wagon maker, cabinet maker, blind maker and upholsterer, two bonnet makers, carpenter, insurance maker, Baptist church and Orange Lodge.
In 1887 Haines added a store, hotel and two storey house after a fire in 1886, destroyed an entire block of original buildings including Henry's hotel. Many of those reconstructed buildings remain to this day. The town received telephone service in 1910 and has 124 subscribers.
In 1914, the Interprovincial Brick Company took over the brick making operations on Mississauga Road to expand their own brick making operations. Six downdraft kilns and one continuously firing kiln allowed the company to produce 90,000 bricks at once.
To provide accomodation for their workers, the company established a small town on the site. Rent was $13 a month which was cheaper than nearby Terra Cotta.
A fire in 1948 destroyed the grist mill. It is not known if it was rebuilt or not.
The town's population began to decline in the 1950's. The brick making continued until 1958 when the Interprovincial Brick Company ceased operatons. Domtar took over the site and demolished the workers homes.
In 1993 Brampton Brick reopened the brick yards for shale extraction. They have preserved the original brick works behind a chainlink fence.
