Short spoke about David Letterman's retirement as host of Late Night on Wednesday, just hours before the final episode of the long-running talk show aired on CBS.
"I think he created a kind of originality and an irony and anarchy to late night that had never existed," said Short outside the ballroom of the Royal York Hotel in downtown Toronto. "He is just one of the great original comedic minds that exists in the entertainment field.
"It's a little sad when you feel that that person's not going to be in front of us every night."
Short was attending a fundraiser for Parachute, a charity dedicated to children's safety.
The SCTV and Saturday Night Live alum and native of Hamilton also hosted his own talk show, Primetime Glick, where he interviewed celebrities as the character Jiminy Glick.
