The Black & Gold lead the bleu, blanc et rouge by three points as the teams battle for Northeast Division supremacy and for one of the top three spots in the Eastern Conference.
But the B's, just 4-3-3 in their last 10, face the Canadiens (6-4-0 in their last 10) and Boston has not yet found much success against their arch-rivals.
"Well, we haven't played well against them," said Boston Bruins Head Coach Claude Julien post-practice on Wednesday.
"I think they've played well against us.
"Hopefully, if we can build on last night's performance and last night's effort hopefully that will be a better game for us tomorrow."
Asked if the game versus the Canadiens would present even more of a playoff atmosphere than usual, given the distinct possibility that the Bruins could face the Habs in the first round, Julien said, "Yeah, it's going to be one of those games."
But the B's bench boss cautioned against looking too far ahead.
"Again, we don't know what's going to happen from here on in," said Julien. "There's a lot of different scenarios that could happen and you know you never choose your opponents.
"But what you want to focus on is winning the game tomorrow. We know what it means in the standings and you know you can either let them get right back behind you to within a point or you can spread that [lead] a little bigger and make it even tougher for them to catch up to us.
"Based on that, I think it's important for us to be ready to play well and [that's] something that I mentioned earlier that we haven't done well against this team so far this year," he said.
Julien continued to talk about last night's win as a stepping stone to greater success in the stretch run rather than a benchmark.
"I think in moving forward here, there's a lot for us to work on and to build on," he said. "That's what we are doing right now and that's where our focus is.
"I don't think you look at that as 'everything is okay now,'" added Julien. "I think we've got to continue to build on [last night's victory] and I think we've got to continue to play hard and focus on the things that obviously gave us a win last night.
"But, you know, a losing streak is...consecutive losses. And a winning streak is consecutive wins and I don't think we've gotten there yet."
