We stopped by the harbourfront Centre after visiting the aquarium and CN tower. We didn't get a chance to walk around the entire harbour. We took a boat ride around the city's waterfront area and enjoyed the views and historical information we received.
We saw several areas where you can sit and just people watch. There were some cool boats docked. They had a small concert area with seats. There were several restaurants and vendors to buy snacks. I would love to return to actually enjoy more of the scenery especially on a beautiful spring/summer day.
