Former Ontario Superior Court Justice Roydon Kealey referred to Henderson as "one of three top lawyers in Canada. He was a legend, a prodigious worker, and more or less a genius." Ian Scott, former Attorney General of Ontario, called him "the best all-round lawyer the profession has produced since the War."^[7] He was known as a "lawyer's lawyer" by the Ottawa community, and by his colleagues as "a gentlemen, a character, and Canada's most respected lawyer".^[8] By the time of his death, Henderson appeared as counsel in nearly 400 reported cases, including 90 before the Supreme Court of Canada.^[7] Henderson never retired.^[9]

Henderson was twice offered a judgeship. On the first occasion, early in his career, he was asked to be in on the trial division of the Ontario High Court. He rejected the offer because he thought at his age he would not be effective on the bench. The second offer came in 1972 from John Turner who asked Henderson to accept an appointment to the Ontario court of appeal. He initially accepted but eventually decided against it.^[11]
