Boucher entered Monday's game after Toronto took a 4-1 lead in the second period.
Boucher, 36, was 2-4 with the Phantoms and had a 2.71 goals-against average and .908 save percentage.
Wayne Simmonds, who missed three games with a concussion before returning Saturday, said the rust has been removed from his game.
"I'm starting to get the timing back. I shouldn't have any excuses," he said before scoring 38 seconds into Monday's game.
Simmonds grew up in suburban Toronto, and he left about 15 tickets for relatives and friends. The winger was a big Blue Jays fan as a youngster and, as a five-year-old, watched the World Series on TV with his grandmother as Joe Carter hit the clinching home run to beat the Phillies in Game 6.
"That was a pretty cool experience," Simmonds said.
The media swarm that surrounded Luke Schenn made it seem like a Stanley Cup Final, not an early-season game. Schenn was making his first appearance in Toronto since being dealt to the Flyers for James van Riemsdyk in June.
"It'll be good to get the game out of the way," van Riemsdyk said Monday morning. "Obviously, I had some great memories in Philadelphia, but it's time to move forward."
Brayden and Luke Schenn live in different condos but in the same Philadelphia complex. "We're pretty much together 24/7 - breakfast right to supper, we do it all. It's been good," Brayden Schenn said. "We're not sick of each other yet."
