Adventure Crossroads Incorporated traces its beginning to 1969 when a group of Mennonite volunteers decided to become involved in the lives of Winnipeg's inner city people. They formed a group called the Inner City Community Ministry Project. One of their first projects was to coordinated a camp for disadvantaged families. In 1971, Inner City Community Ministry Project changed its name to Crossroads and on January 14, 1974 Crossroads incorporated to become Adventure Crossroads Inc.
Crossroads worked on the premise that many people who needed help were not taking advantage of resources available to them. In order to alleviate this problem, members of Crossroads tried to develop personal relationships with people in the inner city in order to foster a greater sense of community and promote greater involvement.
Crossroad attempted to develop these personal relationships through their programs such as creating a receiving home, a foster home, and a learning centre for children with behavioral problems called Alexander Place. One of their largest and longest lasting projects was a family centre. Run at first out of Maclean House and then later out of 211 Isabel Street, this family centre provided a place for residents of the area to gather and participate together in activities.
A few Mennonite churches provided most of the volunteers and financies. When Crossroads became Adventure Crossroads Incorporated, a board was created consisting of representatives from these churches. Although volunteers made up the majority of the staff, there were also various employees.
Adventure Crossroads official dissolved on November 30, 1995.
