I expect that FSN is broadcasting the game in SD only, since it is an away game and is in Canada. I don't recall ever seeing an American HD broadcast from Canada on Center Ice. The only time any NHL HD broadcasts are seen in the U.S. are when the are on Versus or the NHL Network.
Just checked the actual RSN and the game is listed in HD in the guide as well on FSND HD. I cannot check to see if the game is actually in HD since I do not have CI. Perhaps someone else can determine if it is FSND or Dish?
