Niagara Queen II

The Niagara Queen II is a small icebreaker that Ontario Power Generation uses to keep the inlet ports open at their plant on the Niagara River at Niagara Falls.

Niagara Queen II is a shallow draft river vessel designed by OPG and STX Marine. She replaced the Niagara Queen, a modified tugboat icebreaker operated by Ontario Hydro and now with OPG.
