Vanderpool retired in 2005 with a 24-7-4 professional boxing record with 13 knockouts. He had won five national and international titles during his professional career. In March 2013, after a 7.5-year hiatus from professional boxing, Fitz came back to win the National Boxing Authority championship defeating an opponent 17 years younger, achieving his 6th professional national title. The victory made Fitz the oldest Canadian Champion in history - succeeding George Chuvalo - and a three-division boxing champion at 45 years of age. Vanderpool came out of retirement and won a six-round decision over Phil Rose on Sept 15, 2012, in Ontario, Canada.^[1] In a second comeback bout at 45 years of age, Vanderpool won a ten-round unanimous decision over Roberto McClellan on March 2, 2013, to win the vacant Canada National Boxing Authority NBA Middleweight title in New Brunswick, Canada, making him the oldest ever Canadian national boxing champion. George Chuvalo was 43 years old when he retained the Canadian Heavyweight title over George Jerome in Toronto in December 1978.^[2][3] The NBA Middleweight title is a new Canadian belt.

Fitz announced his retirement "for good" from professional boxing on January 4, 2014,^[4] during the grand opening of the new location for Vanderpool Fitness with special guest George Chuvalo passing the torch for the oldest Canadian boxing champion.
