The Canadiens are coming home with a 2-0 lead in their Eastern Conference quarterfinal series against the Boston Bruins, but Michael Cammalleri says there's no reason to celebrate.

"If we're sitting here and being happy about that and celebrating, we're making a crucial mistake," said Cammalleri, who sparked the Montreal offence with a goal and an assist in Saturday night's 3-1 win.

"You can be happy and the fans can be happy and our parents and friends can be happy and good for them. But I'm dead serious, we have no time to be happy now."

Cammalleri said the Canadiens can't afford to relax, but they have to be a confident bunch after riding goaltender Carey Price and solid team defence to a pair of wins.

"We kind of expect it from one another," Cammalleri said when asked about the 27 shots the Canadiens blocked in Game 2. "When teams start playing well, you learn to trust one another. I think we expect it from each other and seeing guys earn that trust is how you win."

Price has been the key, stopping 64 of 65 shots over the two games.

Cammalleri said communication has important in Price's success.
