In 1826, Jacob Gabel started a tannery; Robert Douglas started a brewery and John Galt established Ancaster as his headquarters for the Canada Company. 1827 marked the year that inaugurated the publication of George Gurnetts Gore Gazette and the Ancaster, Hamilton, Dundas and Flamborough, Ontario Advertiser. By 1835, Job Lodor was the only person in Upper Canada who managed to obtain banking privileges and thus the Gore Bank was established in the village in 1836. Also in 1836, the population of Ancaster would reach 2,664. In 1837 a group of Red Coated Soldiers appeared in the village to announce the Mackenzie and Papineau rebellions. By 1840 Ancaster had 5 hotels. In 1844, Dr. Richardson opened his practice in the village. Eyre Thuresson founded a threshing machine factory in 1846, a stone mill in 1862, another card mill upstream in 1863 and reorganized the Cane Knitting Factory in 1865. In 1847, N. and E. Wiard re-opened the McLaughlin foundry to make ploughs. Harris and Alonzo Egleston arrived in 1832 and began working at William Wiards foundry and eventually bought him out. The Eglestons then proceeded to expand their own business empire which included building a foundry in 1843 employing 25 people and rebuilding a gristmill in 1863 at the present day location of the Old Ancaster Mill on the old Dundas Road. This Egleston mill was the 4th Ancaster mill and the third to be rebuilt at this current location. Wilsons original mills burnt down in 1812. Upon rebuilding, Wilsons mills were relocated from this original site at Wilson and Rousseaux Street a little further downstream and rebuilt in stone at the present Old Ancaster Mill location on Old Dundas Road. Again, at the same location, a second mill burnt down in 1818 as well as a third mill that was damaged by fire in 1854. Wilsons original 1791-1792 mill foundations still exist 75 yards upstream from the Wilson and Rousseaux Street intersection but are hidden with vegetation. The much restored and modified remnants of Eglestons 1854 mill now operates as a restaurant and banquet hall. The Barracks of 1812 still stand as a reminder of the War of 1812. By May 1866, the first public telephone was set up in Gurnetts store but was disconnected from lack of use.
