Next week I need to transfer in Gander, from Halifax, en route to St. John's.

Few questions....
1. I presume I don't have to clear security, as I would have cleared it in Halifax. Correct?;
2. I was told that there is no Maple Leaf Lounge (I am a SE). Are there any outlets airiside from where I can buy something to eat or drink?; and
3. Is there Wi-Fi?

Ideally, I wouldn't care, but I have three hours in Gander.
