Brubacher House
The Brubacher Farm House Museum is a distinguished home built in 1850 by John E. Brubacher, a Pennsylvania German Mennonite settler. In 1979 the University of Waterloo officially opened the house as a museum in recognition of the University's location on what was once Mennonite farmland. The museum is operated by Conrad Grebel University College and the Mennonite Historical Society of Ontario.

Project Ploughshares
Since its founding in 1976, Project Ploughshares has promoted the concept of "common security": that security is the product of mutuality, not competition; that peace must be nurtured rather than guarded; that stability requires the reduction of threat and elevation of trust; and that sustainability depends on participatory decision-making rather than on exclusion and control.
Project Ploughshares promotes disarmament and demilitarization, the peaceful resolution of political conflict, and the pursuit of security based on equity, justice, and a sustainable environment.

DaCapo Chamber Choir
DaCapo is a community chamber choir formed in the fall of 1998.

The performance season consists of three annual concerts in Kitchener-Waterloo, one in fall around Remembrance Day, a mid-winter and a spring concert. Additionally, the choir performs on an ad hoc basis at other events.
