"That's not the way we wanted to do it," Gionta said. "We had a good two periods, then we sat back in the third and they got themselves back into it."
Tampa Bay, which opened the season 6-1, has since lost five in a row (0-4-1).
"In the third period, our character showed up, again," Tampa Bay coach Guy Boucher said. "We have to build on a positive. That's extremely positive."
After Subban scored on a blue line shot at 8:21 of the second, Moen made it 3-0 from the low slot with 1:06 to go in the period. Moen snapped his 21-game goal drought, dating to Dec. 31, 2011, against Florida.
Gionta put Montreal ahead 1-0 when he tipped a pass through the crease from
Tomas Plekanec past Lindback during a 5-on-3 power play with 43 seconds left in the first.
Hedman received a roughing penalty that set up Tampa Bay's two-man disadvantage. The Lightning allowed one goal on seven short-handed situations.
"A lot of the penalties ... I won't say anything," Boucher said.
Tampa Bay went 1 for 5 on the power play.
The Canadiens had a couple of quality scoring chances early in the first. Lindback made a save on Colby Armstrong's backhander during a 2-on-1, and
Andrei Markov hit the post with a drive.
Lindback also made a lunging blocker stop on Markov's rebound attempt.
Price stopped an in-close redirection by
Vincent Lecavalier late in the first, and had a glove save on Stamkos' shot from the right circle during a second-period power play.
