Mr. Maccagno ran for a seat to the Alberta legislature in the 1955 provincial election as a candidate for the Alberta Liberals in the electoral district of Lac La Biche. He defeated incumbent Social Credit MLA Harry Lobay by less than 100 votes. When he was re-elected in 1959, he was the only Liberal with a seat in the legislature.
In 1964, when Liberal leader Dave Hunter resigned after failing twice to win a seat in the legislature, Maccagno became interim leader of the Alberta Liberals as well as Leader of the Official Opposition. He became the first Italian Canadian to become head of a major political party in Canada. In 1966 Calgary Alderman Adrian Berry was chosen as Liberal leader, but resigned shortly after, leaving Maccagno to resume the leadership.
Mr. Maccagno lead the Liberals into the 1967 general election. The party lost over 8% of its popular vote from the last election, but kept all three seats it held on dissolution. The Liberals became the third party after Peter Lougheed's Progressive Conservatives.
Mr. Maccagno resigned his seat in the Alberta legislature on May 27, 1968 to run in that year's federal election. He ran for the federal Liberals in the electoral district of Athabasca and lost to Progressive Conservative candidate Paul Yewchuk by about 1,200 votes. After the election he was appointed to the National Parole Board.
