Edighoffer was born in 1928 at Stratford, Ontario,[2] grew up in Mitchell, was educated at Pickering College and worked as a retail merchant in the clothing business before entering provincial politics. He also served on the town council for Mitchell in 1958 and 1959 and was mayor from 1960 to 1961.[2]
The Liberal Party, which had been out of power since 1943, formed a minority government after the election of 1985. Edighoffer, who had served as Deputy Speaker in a previous minority parliament, was appointed Speaker of the Legislature on June 4, 1985 after the toppling of the Frank Miller's government in a motion of non-confidence. Edighoffer was nominated and seconded for the Speaker's position by the leaders of all three political parties represented in the legislature, and was generally regarded as an impartial officeholder.[2] He was re-appointed as speaker on November 3, 1987 following that year's provincial election. He served in the position for another three years, and did not seek re-election in 1990.[2]
Edighoffer's painting in the Ontario legislature was painted by Istvan Nyikos, a Hungarian-born Canadian artist.[11]
