OTTAWA -- Jake Allen made 22 saves, Phillip Danault and Brendan Gallagher had a goal and an assist each, and the Montreal Canadiens defeated the Ottawa Senators 4-1 on Thursday night for their third consecutive win.
Paul Byron and Corey Perry provided the rest of the offence for Montreal (16-8-9), which blanked the Edmonton Oilers 4-0 some 48 hours earlier in the Canadiens' return to action after a week off with two players in the NHL's COVID-19 protocol.
Jake Evans added a pair of assists to register the first two-point game of his career. Tomas Tatar added two assists of his own for Montreal.
Allen picked up his first victory since making 34 stops in a 2-1 win over the Senators on Feb. 6.
Connor Brown replied for Ottawa (12-21-4), while Filip Gustavsson made 34 saves. The Senators played for the first time since losing 3-2 to the Toronto Maple Leafs in overtime on March 25 thanks to a schedule rejig following the Canadiens' COVID-19 issues.
Montreal won three straight for the first time since the end of January, and comfortably occupies the fourth and final playoff spot in the North Division, six points up on both the Calgary Flames and Vancouver Canucks, with four games in hand.
The Canadiens are also now just four points back of the Oilers in the standings, with four games in hand.
Ottawa, meanwhile, saw its five-game point streak (2-0-3) come to an end in dropping to 3-3-0 against the Canadiens in 2020-21.
The teams were supposed to play Sunday in Montreal, but that game was the fourth of four contests postponed after Canadiens forwards Jesperi Kotkaniemi and Joel Armia went into COVID-19 protocol. One of the players in question tested positive for a variant of concern.
Montreal and Ottawa were also scheduled to hit the ice Tuesday in the nation's capital, but that game was rescheduled to allow the Canadiens and Oilers, who were slated to play three times last week, to get in at least one of the postponed games.
After coming close early when Nick Suzuki hit the post, Montreal opened the scoring at 10:48 of Thursday's first period on a lucky break. Gallagher's initial shot from the right side pinballed off Ottawa centre Colin White and defenceman Thomas Chabot in front to Danault, who fired his third of the season into a wide-open net.
Without a goal in his last eight games coming into Thursday, Senators rookie Tim Stutzle was flying early with a couple of slick setups that just failed connect before a nice individual effort that Allen turned aside.
Ottawa got a power play that stretched from the end of the first into middle period, but the Canadiens doubled their lead 48 seconds after the break when Byron took a pass from Evans and backhanded his third upstairs on Gustavsson following some horrendous coverage in the Senators end.
The goal was Montreal's league-leading eighth short-handed goal of the season, and first since the 11th game of the season.
The Senators had an excellent opportunity to get back within one, but Allen, who played for the first time since March 19, made a desperation stick save on Brady Tkachuk with the Ottawa winger staring at a yawning cage.
Suzuki then moved in alone on a breakaway only have both his initial shot and rebound effort stopped by Gustavsson as the visitors led by two through 40 minutes.
Montreal winger Josh Anderson hit another post early in the third, but Perry scooped his seventh of the campaign, and fourth in the last nine games, upstairs to make it 3-0 at 4:43.
Gallagher scored at 10:04 with his 14th, and third in as many games, off a pass from Danault to make it 4-0 before Ottawa broke Allen's shutout bid with under two minutes to go on a power play with his eighth.
