Matrundola won the Ontario Liberal Party nomination in the riding of
Armourdale for the
1985 Ontario election, but lost the election to
Progressive Conservative incumbent
Bruce McCaffrey by 212 votes. The election resulted in
David Peterson's Liberals forming a
minority government. When the province returned to the polls in
1987, the Liberals won a
majority government. Matrundola was elected in the newly created
riding of
Willowdale, which incorporated much of Armourdale, defeating
Progressive Conservative candidate
Charles Harnick. Matrundola served as a
backbench supporter of the
David Peterson government. He was appointed Deputy Government
Whip in 1989. Peterson called an early election in
1990 which resulted in the Liberals being upset by the
New Democratic Party. In Willowdale, Matrundola lost to Harnick by 834 votes, marking one of the few gains by
Mike Harris's Tories in this election. Matrundola attempted a political comeback but was defeated for the provincial Liberal nomination for the
1995 provincial election by
Les Scheininger. ==Later life==
