[4] Baron Byng High School's alumni include many accomplished academics, artists, businesspeople and politicians.

Baron Byng has been immortalized in many books, including in Mordecai Richler's The Apprenticeship of Duddy Kravitz, St. Urbain's Horseman, and Joshua Then and Now as Fletcher's Field High School.

[8] The population of Baron Byng was consciously constructed to be Jewish by the Board, which sought to segregate Jews to avoid the dilution of English-Canadian culture and Protestant religious instruction taught in their public schools.

[11][12] In April 1945, Baron Byng held a commemorative service for the second anniversary of the Warsaw Ghetto Uprising, sponsored by the Canadian Jewish Congress; speakers included Baruch Zuckerman and Michael Garber.

[15][16] After the school's closure, the Baron Byng building became home of the non-profit community organization Sun Youth.
