 After competing for a Canadiens roster spot in the 2007 NHL pre-season, Lapierre was returned to the Bulldogs to start the 2007–08 season. On December 5, 2007, he was recalled to the Canadiens, earning a role as the club's third or fourth line centre. His time with the Canadiens increased as he spent 53 games in the NHL with seven goals and 18 points, while registering 14 points over 19 games in the AHL.
 By the 2008–09 campaign, Lapierre had established himself as a full-time NHLer and earned a roster spot with the Canadiens out of training camp for the first time in his career. Just over a month into the season, he was elbowed in the head by opposing forward Jarkko Ruutu during a game against the Ottawa Senators on November 11, 2008. Lapierre was not injured on the play, while Ruutu received a two-game suspension for the infraction.

In the 2010 playoffs, Lapierre helped the Canadiens advance to the Eastern Conference Semi-finals, scoring goals in Game 6 of the first round against the Washington Capitals and the second round against the Pittsburgh Penguins, both elimination games. However, the Canadiens were eliminated in the third round by the Philadelphia Flyers; Lapierre finished the playoff season with three goals and one assist in 19 games.
 On December 31, 2010, after five-and-a-half seasons playing within the Canadiens organization, Lapierre was traded to the Anaheim Ducks in exchange for defenceman Brett Festerling and a fifth-round draft pick in 2012. He made his Ducks debut on January 5, 2011, in a 4–1 loss to the Nashville Predators. The following game, he recorded his first point as a Duck, assisting on a goal by Matt Beleskey in a 6–0 win against the Columbus Blue Jackets.

Upon his arrival in Vancouver, Lapierre's reputation as an agitator was addressed by Vigneault and he was asked to reduce activity in between whistles, such as trash talking and unnecessary hits. Lapierre scored his first goal as a Canuck on March 16, 2011, in a 4–2 win against the Colorado Avalanche. While the Canucks originally acquired Lapierre with the intention of playing him on the fourth line, he soon moved up to the third with the injury of Manny Malhotra late in the season. Between Montreal, Anaheim and Vancouver, he finished the season with six goals and six assists over 78 games. Centring the third line with wingers Raffi Torres and Jannik Hansen during the 2011 playoffs, Lapierre added three goals and five points over 25 games.
