Barré-Boulet, an undrafted free agent, currently leads the QMJHL in both goals (49) and assists (55) through 57 games with the Blainville-Boisbriand Armada.
The 20-year-old Montmagny, Que., native has spent the past two seasons with the Armada following three years with the Drummondville Voltigeurs.
Barré-Boulet has 136 goals and 325 points in 255 career games in the QMJHL.
The signing serves as a way for Yzerman and the Lightning to restock the organization’s prospect shelf, so to speak, as they dealt defensive prospect Libor Hajek and forward prospect Brett Howden to the New York Rangers at Monday’s trade deadline in the move that helped them acquire Ryan McDonagh and J.T. Miller.
