Galliano was creative director at Christian Dior when he was fired in 2011 for an anti-Semitic rant. He's currently involved in a lawsuit against his former employer.
The school said in a statement that his appearance was to include "a candid discussion about the connection between his professional work and his actions in the world at large." It said it canceled the workshop after the two sides couldn't reach consensus on the conditions of the conversation.
A spokesman for Galliano didn't immediately return a request for comment Wednesday.
Earlier this year, the designer began a temporary artist residency at the studio of Oscar de la Renta in New York.
