Iginla fired a slap shot from the right circle past Mason to make it 2-0 just 17 seconds before the first intermission.
A turnover by defenseman Nicklas Grossmann led to Boston's third goal.
Smith stepped around Grossmann and swiped at the puck, which hit the post, hit Mason and went in.
Rask kept it 3-0 with his toughest save, a sliding glove stab going right to left to rob Jakub Voracek on a one-timer.
Bergeron made it 4-0 minutes later, sending Mason to the bench.
Giroux and Iginla traded power-play goals in the third. Chara then scored his second goal on the man-advantage.
