Yeah, it's true.
After the arena was empty, the Canadians took their celebration out of the dressing room and onto the ice. An AP reporter saw this and apparently asked IOC officials which prompted the investigation.
One member was under age by BC laws, but legal in Alberta (where she is from).
1. They should have known better
2. Especially with the under age girl
3. Smoking (of any kind) is disgusting
4. It's absolutely pathetic that the reporter ran out and tattled on them to make a story for himself
5. Be extremely careful when a gazillion news outlets are looking anywhere to get a story
Unfortunate, mildly embarrassing, an apology has been issued, somebody's wrist will get slapped and the whole thing wil be forgotten in a couple of days.
Edit: Shoe Lady, I tell Americans on here to stop spreading lies, so I'll also tell the Canadians: the US team did not stomp on our flag, that was a lie and we need to move on.
