Born Peter Cory Landry in Toronto on August 7, 1921, he moved to Montreal with his family and eventually went on to play with the McGill varsity squash club for three years before graduating with a bachelor of engineering in 1948 and a master of science in 1962.
A former professor of education and physics at McGill, Landry was the first Canadian university player inducted into U.S. National Intercollegiate Squash Racquets Hall of Fame in 1995.
In 1940-41, he became the McGill squash team's first manager and after the war, initiated numerous matches against American universities and Montreal clubs.
In March of 1946, Landry organized the first intercollegiate squash match in Canada, a 6-4 win for McGill over Toronto and he won both of his matches against the Varsity Blues top two seeds. In 1946-47, he was team captain and defeated the top seeds of Princeton, Yale and Harvard. He went undefeated in Canadian intercollegiate squash circles from 1946 to 1948.
At the New York University Club in December of 1946, he became the first player from a Canadian university to win the U.S.A intercollegiate invitational squash tournament. In March of 1947, Landry was also the first Canadian university player to win the U.S.A. intercollegiate championship.
He represented Canada more than half a dozen times in Lapham Cup match play and in 1947, was the first McGill undergraduate to become Quebec singles champion.
