He served in the Legislative Assembly of Manitoba as a Liberal-Progressive from 1949 to 1959, and was a cabinet minister in the government of Douglas Campbell. His father, N.W.P.

Shuttleworth worked as a farmer before entering political life. He served as reeve of the rural municipality of Odanah, and was president of the Manitoba Approved Flock Owners. He was a member of the United Farmers of Manitoba.
He was first elected to the Manitoba legislature in the 1949 provincial election, defeating Progressive Conservative E.P. Venables by 241 votes in the rural constituency of Hamiota.

On July 6, 1956, he was also appointed Minister of Agriculture. He was responsible for overseeing the Rural Electrification Program.
