Winterbourne (/ˈwɪntərbɜːrn/) is a village located to the east of the Grand River in the township of Woolwich in the Regional Municipality of Waterloo, Ontario, Canada.

[1] The Crook's Tract, located east of the Grand River, began to attract dozens of families from England and especially from Scotland.

Previously, the tract had few settlers, the most notable a Mr. Cox; the creek which enters the Grand River at what is now Winterbourne was named after him.

[2] Captain Henry Lanphier arrived in 1854 and soon built a sawmill and flour mill after damming Cox Creek.

[10] Winterbourne was longed served by Chalmers Presbyterian Church located on the main Katherine Street.

The church was offered for sale in 2012, and a number of local residents, fearing that the church would be purchased then demolished, approached the Township of Woolwich to request that the property be flagged as a potential heritage building, thereby ensuring that there would be public debate should potential owners want to demolish the 1870 building.

Woolwich Township did indeed "flag" the building, ensuring that prospective buyers were aware of the cultural and heritage significance of the church.
