I had a Living Social Deal for the Shark Attack but the boat was out of commission so they substituted this boat tour. This tour is only $12.86 if you prebuy it online.
The Harbour Star offers a 45 minute relaxing boat tour on the harbour with not much narration. It did allow for some fantastic pictures of the Toronto skyline though.
They were supposed to discuss the following sites...but did not. They did discuss a couple of these though.
Toronto's amazing skyline
Billy Bishop Toronto City Airport
Hanlan's Point
Gibraltar Point Lighthouse
Wildlife Sanctuary
Centre Island/Centreville
Island Yacht Club/Muggs Island

Ward Island/Algonquin Island
Royal Canadian Yacht Club
Queen City Yacht Club
Polson Pier

All in all, our guide seemed friendly and it was a relaxing tour.
