Pickup Hockey at Newnham?

I'm starting school in September. I just got back from Wasaga Beach where my dad had a 50th anniversary of his team winning big back when he played hockey as a kid. There was a game of pickup hockey so I brought my gear and had a blast. I now have the bug to play again and I'm wondering if there's something like that at the Newnham campus? Just a fun game, skate and goof around for a hour, and maybe post-game eats and drinks.
