In 1861, Asa Belnap Foster, a prominent Canadian railway builder and politician, brought the railroad to Waterloo which helped expand the village to a thriving town. Its population increased from 200 in 1857 to 1500 in 1867. Foster developed the south end of the town where the railway station was located and connected the old village to it by constructing Foster Street, at his own expense, which still exists today as Waterloo's main street. A. B Foster also donated the land for all the churches in town plus the local high school. Additionally, Foster also rebuilt Lewis Bridge at his own expense when the bridge fell into disrepair. In 1864 Colonel Foster built Maplewood, a beautiful estate on Clark Hill. When Waterloo was incorporated in 1867, A.B. Foster was elected its first mayor.
