Alexander then attended Osgoode Hall Law School in Toronto. While there, he suggested to the Dean during a lecture that he was using inappropriate language: "nigger". Challenging the Dean he said: "But you can't say that because you have to show leadership. You're in a position of authority, a leader in the community. A leader has to lead and not be using such disrespectful comments without even thinking about them." Of the incident he recalled: "I don't know what ever made me stand up and ask him that in a class of 200 people. ... But I will tell you one thing, that day made me a man." His actions did not end his career as he feared and Alexander graduated from Osgoode Hall in 1953.
