Canada spent ($ in dollars) to dredge and widen the Eastern Gap, making it the primary entrance to the harbour for commercial boats. The of material was used to build the aquatic park on the Outer Harbour headland. In June 2004, the company Canadian American Transportation Systems (CATS) began regular passenger/vehicle ferry service between Pier 52 and Rochester, New York using the vessel Spirit of Ontario I. The service used a marketing name called "The Breeze". While Rochester had a custom-built ferry terminal, the Toronto terminal was a temporary facility, near the end of Cherry Street for security and customs screening facilities while a permanent marine passenger terminal was still under consideration for construction.

Even with impressive passenger numbers by the winter of 2006 the ferry service lost funding from the City of Rochester and announced that it would no longer be in business. The terminal building was later used for filming the CBC crime drama The Border.
