Defensemen Erik Gustafsson and Luke Schenn each made their debuts for Toronto.
Gustafsson had one blocked shot in 9:52 of ice time after being acquired with a first-round pick in the 2023 NHL Draft from the Washington Capitals on Tuesday for Rasmus Sandin. Schenn had four hits and two blocked shots in 10:42 after being acquired from the Vancouver Canucks for a third-round pick in the 2023 draft on Tuesday.
"When you hear that Toronto's in the mix, obviously, you're kind of excited," said Schenn, who played four seasons with the Maple Leafs from 2008-12. "Following from a distance, the season they've had and the talent they've got around here and how they're gearing up and building for hopefully a good postseason here, you want to be a part of that. This is the best time of the year, being in the stretch run like this."
Blake Coleman scored, and Jacob Markstrom made 32 saves for the Flames (27-22-13), who have lost four in a row (0-2-2) and lead the NHL in one-goal games and losses (13-11-13).
"We all hate losing," Coleman said. "It's honestly pretty incredible how many one-goal games we've lost this year. The best way to sum it up and the only thing I can think of right now is we're a great team that just doesn't know how to win right now.
"We all feel like we could be a team in a much better position right now, but at the end of the day, it's points and structured the way it is for a reason. You've got to win hockey games, and we've just found way too many ways to lose."
