Fawcett won a 1965 by-election brought on by the resignation of Osias Godin. He represented Nickel Belt for three years, and was defeated by Liberal candidate Gaetan Serré in the 1968 election. Following his defeat, he was re-elected to Capreol's town council, and retired from politics in 1991.
Fawcett's daughter is married to Elie Martel, who was the Member of Provincial Parliament for Sudbury East from 1967 to 1987. Shelley Martel, Elie Martel's daughter and Fawcett's granddaughter, won election to the Legislative Assembly of Ontario upon Elie Martel's retirement, and continued to represent the riding of Nickel Belt until her own retirement from politics in 2007. She is married to current Ontario New Democratic Party leader Howard Hampton.
