Harbour Station arena in St John, New Bruswick has a breastfeeding room (includes breastpumping) with comfortable padded chairs and changing area.
This means more than one mom can nurse at a time, which helps reduce for other waiting nursing moms.
Harbour station stated on their website:
"There is a comfortable private room on the Arena Level reserved for nursing mothers. During some events this room may be unavailable due to security requirements. Please contact an Event Staff person for directions."
The room also can be locked, but we are not aware of an electric outlet for powered breastpumps. We will inquire and update this nursing room soon.
