Ducharme was retained by Alexandria Morra on the weekend.
Ducharme tells CBC he expects the case will go to trial.
Morra is charged with one count of committing an indecent act in a public place.
The charge follows a CBC investigation that uncovered dozens of sexually explicit performances that were seen live online from two libraries.
The woman in the videos used the screen name "lilsecrett."
She's due back in court in April.
