He ran for a second term in the 1955 general election and was defeated by Liberal candidate Richard Hall. He led on the first count but was defeated on second choice preferences.^[2] He regained the seat for Social Credit in the 1959 election, defeating Hall by a large majority.^[3]

In the 1963 general election, Aloisio faced a strong challenge from provincial Liberal leader Dave Hunter, but managed to hang on to his seat.^[4] Hunter and Aloisio faced each other again in the 1967 election. Aloisio held the seat with an increase in his vote and Hunter finished a distant third.^[5]

Aloisio retired from the legislature at dissolution in 1971.
