The Liberals are hoping to keep the West Island riding of Jacques Cartier in the family.
CTV Montreal reports Greg Kelley, son of outgoing veteran Liberal MNA Geoff Kelley, will run for the party in the riding, which covers the western tip of the island of Montreal.
Geoff Kelley announced in June he wouldn't be seeking re-election.
He's held the riding since 1994.
Greg Kelley's nomination will be announced Wednesday morning.
Kelley has worked as a political advisor since 2014.
