In Pokémon Platinum, Glaceon can be found on Skier Lexie on Route 217. She's straight down from the entrance from Acuity Lakefront.

Gym Leader Candice also uses Glaceon in the Survival Area, but you won't be able to battle her there before seeing Glaceon.

There's a skier on Route 217 that has a Glaceon. She's Skier Lexie.
