Veleno has been playing on a line with Lafreniere at the showcase.
"He's dynamic in every sense," Veleno said. "He can score, he can pass, he has great hockey sense and he's easy to play with. For any center or wing, he's easy to find on the ice and he makes his linemates better. He's just an amazing player."
Lafreniere was awarded the Michel Briere Trophy as most valuable player of the QMJHL after he had 105 points (37 goals, 68 assists) in 61 regular-season games and 23 points (nine goals, 14 assists) in 13 playoff games last season.
"Hockey players love pressure," Canada coach and former NHL forward Dale Hunter said. "You want to be playing in the World Junior Championship, in the final game of the Stanley Cup Final. You want to be on the ice for overtime. Alexis is a kid who enjoys the game. There's always going to be pressure, but that's the great thing about hockey because when you retire, you miss that pressure. I think he'll embrace it and enjoy it."
Rimouski's Colten Ellis, one of five goalies competing for a spot at the position for Canada, is probably the player most familiar with Lafreniere's tendencies.
"Alexis deals with pressure like a professional," Ellis said. "Obviously, he's been dealing with any type of pressure at a young age. Just seeing the way he handles himself on and off the ice and deals with that is pretty cool.
"His shot is pretty lethal. He's got a quick release and good accuracy, so to be able to go up against him in practice every day is really challenging for me. It's a challenge I like."
Lafreniere, now 17, said his shot is an underrated part of his game.
"This summer, I've been getting a lot better with my shot and I'm still trying to improve it even more because I think it's a big asset if you're going to play in the NHL," he said.
