The winger scored a short-handed goal early in the second period against the Lightning to reach his milestone and give Toronto a 1-0 lead. He later scored a power-play goal in the third period of the Maple Leafs' 4-3 overtime loss.
"It's cool," Marner said. "I grew up in the city. I love being part of this team nowadays. It's special to me. It's special growing up to watch this team play hockey. Now to have my name on something amazing, it's hard to describe."
His streak began in the Maple Leafs' overtime loss to the San Jose Sharks on Oct. 27. It is the longest active streak in the NHL. Marner previously matched the franchise-high 18-game mark set by Darryl Sittler (1977-78) and Eddie Olczyk (1989-90) with an empty-net goal in Toronto's win last Wednesday over the Sharks.
Both Sittler and Olczyk got in touch to congratulate Marner on the feat, something the Toronto-area native said was, "Just cool to have those two legends reach out. ... If you'd told me growing up that this [streak] would happen, I'd have never believed it."
The 25-year-old has now collected at least one point in 24 of 26 contests this season. Marner has tallied 10 goals and 24 points during this 19-game stretch and sits tied for the fourth-most helpers in the league.
Toronto's top-six stalwart has been a dominant playmaker throughout his career and regardless of who he has played with in the Leafs' lineup. Marner's latest linemate Saturday in the record-setting tilt was Nick Robertson, the brother of Dallas Stars forward Jason who is right on Marner's heels with a 17-game point streak of his own.
Beyond Marner's critical role in Toronto's success at 5-on-5, he's an integral part of both Leafs special teams units. Marner leads all Toronto forwards in average ice time (21:28) and short-handed ice time (2:14).
Tampa Bay forward Alex Killorn scored from the right circle 33 seconds into overtime, beating Toronto goaltender Matt Murray and spoiling Marner's heroics. But he can continue adding to his record when Toronto takes on the Stars on Tuesday.
