Elias Lindholm scored the overtime winner to give the Calgary Flames a 6-5 victory over the host Vancouver Canucks on Sunday as the two teams work to finish their regular season while the rest of the NHL has moved to the Stanley Cup playoffs.

Andrew Mangiapane tallied twice, while Josh Leivo, Milan Lucic and Matthew Tkachuk also scored, and goaltender Jacob Markstrom made 30 saves for the Flames (25-26-3, 53 points), who blew a 5-1 lead.

Brock Boeser scored twice while Travis Hamonic, Tyler Graovac and J.T. Miller added singles and goalie Braden Holtby stopped 30 shots for the Canucks (22-28-4, 48 points).

After seeing a big lead disappear, Lindholm netted his 19th goal of the season when his shot from the right circle ricocheted off a defender and into the net 3:24 into the extra period.

The clubs meet again Tuesday in Vancouver and conclude the campaign with a third straight clash the next day in Calgary.

The Flames jumped to leads of 4-0 and 5-1 before falling apart in the third period. Leivo opened the scoring when he intercepted Jonah Gadjovich's pass inside the Vancouver blueline and converted a backhand before the midway point of the first period -- a rough start for Gadjovich in his NHL debut -- before the visitors added a four-goal second period.

Lucic's 10th of the season doubled the lead at 5:48 of the period, and Tkachuk made it a three-goal edge by burying a second chance for his 13th on the season at the 7:17 mark. Mangiapane's goals sandwiched Hamonic's second goal of the season -- the first 48 seconds after Tkachuk's and the second 41 seconds after the Canucks got on the board with 6:39 remaining in the second period -- to give Mangiapane 16 markers on the season.

The hosts stormed back with a four-goal third period. Graovac netted his third of the season on the power play 2:30 into the frame and Boeser added another man-advantage marker at the 7:47 mark. Miller's short-handed tally made it a one-goal game at 11:28 of the period and Boeser completed the comeback with 122 seconds remaining in regulation when he deflected Alex Edler's point-shot blast for his 22nd goal of the season.

Quinn Hughes collected three assists in the loss, Vancouver's third in four outings.
