Calvin Ruck was an anti-racism activist and a member of the Canadian Senate. Ruck held a number of positions within the Nova Scotia Association for the Advancement of Colored People (NSAACP) and was a member for most of his adult life.

Ruck was born on September 4, 1925 to parents who had emigrated from Barbados, settling in Whitney Pier. In 1979, he received his
diploma from the Maritime School of Social Work at Dalhousie University. The School of Social Work now awards a Calvin W. Ruck scholarship yearly.

Rucks organized numerous campaigns from the 1950s and 1960s against businesses in the Dartmouth area, including barber shops, which refused to serve black people. He worked with the Nova Scotia Human Rights Commission from 1981 to 1986. He campaigned tirelessly for the Canadian Government to recognize the heroics of Jeremiah Jones during the Battle of Vimy Ridge.

Ruck was appointed to the Senate of Canada by Prime Minister Jean Chrétien in 1998, where he served until reaching the mandatory retirement age of 75 in 2000. Ruck published two books about Canada’s No. 2 Construction Battalion, the only all-black battalion to serve in World War I. He died at his home in Ottawa on October 19, 2004 at the age of 79.
