Older biographies no longer published in 1999, when Canadian Who's Who records were digitized, are not included in the current database.
All biographies published in 1999 to the present, including biographies created for earlier editions and still published in 1999, are included in the Canadian Who's Who Online database, available through subscription as archived biographies of record.
Biographies that pre-date 1999 are available through print editions of Canadian Who's Who kept at reference libraries. Print editions carry the biographies of Canadians living at the time of publication.
If your library provides access to the Canadian Electronic Library, you will also find the online editions there.
