Assistant Crown attorney Janine Hodgins says police were called to the home in Puslinch Township, Ont., west of Toronto, shortly after midnight on Oct. 17th.
Tommy Hunter said that the two got into a heated argument that night and his son shoved him, causing him to fall down.
The 71-year-old musician, known as "Canada's Country Gentleman," was a major music star who first began performing on the CBC in 1956.
Eventually, he was handed his own program, The Tommy Hunter Show, on CBC Radio in 1960.
The show, which featured guest shots by country stars such as Shania Twain and Garth Brooks, ran until 1992 on television. His last televised special was in 2003 - it drew one million viewers.
The Juno Award-winning performer was inducted into the Canadian Country Music Hall of Fame in 1984 and became a Member of the Order of Canada two years later.
Hunter continues to perform and is slated to launch a tour of Ontario and Western Canada in early January.
