Candy joined the Second City comedy club in the seventies and quickly became a favorite at the Toronto and Chicago theatres, and then on SCTV in Toronto. All the characters he portrayed, whether lovable or mean, displayed a certain vulnerability. Just some of these include: Johnny LaRue, Dr. Tongue, Big Jim McBob, Fishin' Musician, Mayor Tommy Shanks, Harry--The Guy With The Snake On His Face, Josh Shmenge, Stephen Sealy from Pre-teen World, and Mr. Mambo.

Later, John made his mark in Hollywood blockbuster hits such as "Splash" in 1984, "Planes Trains and Automobiles" in 1987, "Uncle Buck" in 1989, "Home Alone" in 1990, and "Cool Runnings" in 1993.

Candy was a proud Canadian and a steadfast supporter of the Canadian Football League. With Wayne Gretzky and Bruce McNall, he bought the Toronto Argonauts. Just a week before his death he was still supporting his team, trying to put together a deal to buy the beleaguered franchise from his partners.

John is survived by his wife, Rosemary Margaret Hobor and their two children, Jennifer (b. 1980) and Christopher (b. 1984).
