New Hope Church was officially formed on January 15, 1956, under the name of Ebenezer Reformed Church. The Ebenezer community was formed by 20 families made of new Dutch immigrants in the Village of Cooksville, now called the City of Mississauga. On January 1, 2018, the name was changed to New Hope Reformed Church of Mississauga after the merger of the congregations of Ebenezer Reformed Church and New Alliance Church of Mississauga.
