Seider assisted on Red Wings captain Dylan Larkin's second goal of the game, becoming the sixth active NHL defenseman to record multiple 40-point seasons before the age of 22.
Raymond, who was playing his 150th career NHL game, was credited with an assist on Jonatan Berggren's first-period goal.
Kasper made his NHL debut for Detroit, registering 14:59 of ice time. As for Edvinsson, his 22:25 of ice time against the Maple Leafs trailed only Seider (22:49).
"Any minute they can get," Lalonde said about Kasper and Edvinsson. "Even last night, we get the open netter. Obviously the game is in hand, but I wanted to get them one or two more shifts in the last two minutes. Just different situations, I think any minute you get out there in any situation is important."
