The events that led to his controversial dismissal began in 1958 when United College Principal Wilfred Lockhart obtained, by mysterious means, a letter written by Crowe to his colleague, William Packer.
In that letter, Crowe had expressed concern with the religious and academic environment at United College and the worrying prospect of a Progressive Conservative victory in the upcoming March 1958 federal election.
Crowe was subsequently fired on the grounds that the letter demonstrated his incompatibility with the "avowed purposes" of the college and his lack of respect and loyalty to the administration.
Crowe's termination prompted local and national concern about academic freedom and the status of tenure in higher education.
"[5] The report further determined that the board of regents mishandled the complaint against Crowe, violating natural justice, due process, and academic freedom.
Following the incident at United College, Crowe worked for several years as a labour researcher for the Canadian Brotherhood of Railway, Transport, and General Workers.
