Wikipedia

Name adopted by the Geographic Board of Canada in 1917 after Edson Joseph Chamberlin (1852-1924), president of the Grand Trunk Pacific Railway at the time. In 1909 Chamberlin became general manager and then vice president of the Grand Trunk Railway. In 1912 he became the president when Charles Melville Hays lost his life on the RMS Titanic. Chamberlin’s presidency differed from Hays’s in that he led the Grand Trunk to expand westward as part of the Canadian transcontinental railway. He remained president until he retired in 1917. Chamberlin died at Pasadena, California, on August 27, 1924.

Unrelated to Rollin T. Chamberlin, the geologist who is namesake of Chamberlin Peak and Chamberlin Glacier, in the Cariboo Mountains about 50 kilometres to the south.
