Johnson leads the NHL with eight goals this postseason.
Johnson's goal was the second game-winner of this round that came at the 19:58 mark of the third period or later, according to NHL.com's John Kreiser. Capitals forward Joel Ward accomplished the feat as well in Game 1 of Washington's second-round series against the Rangers.
The Lightning will host the Canadiens in Game 4 on Thursday night.
