MCS is a charitable organization that offers valuable services to all immigrants and to the wider community. It is governed by a board comprised of representatives from five local Mennonite constituent church groups. MCS took root in the early 1970's when it became evident that Low German newcomers to East Elgin required special help. Mennonite Central Committee Ontario (MCC) contributed some funding to the 'Information and Help Centre'. It quickly became evident that specialized services were required and in 1975 MCC began a small satellite in Aylmer.
As services expanded, the Mennonite churches also began working together. They purchased the building at 16 Talbot Street E and opened a thrift store, Aylmer Mennonite Community Store. Eventually, the building next door at 20 Talbot Street was also purchased and renovated to expand MCC's services to include the Aylmer Resource Centre. In 1999, first steps were taken to localize governance by hiring the first Executive Director to supervise the MCC work as well as the thrift store.
The local Low German radio station, De Brigj - CHPD 105.9, began broadcasting in 2003 and is widely heard in different parts of Canada, Mexico, Paraguay and Belize via live streaming.
MCS services today include:
