By plane
The Toronto City Centre Airport (http://www.torontoport.co...) is on the Toronto Islands, across a narrow channel from the Harbourfront, a ferry runs the short trip from the main terminal building to the foot of Bathurst Street, just south of the intersection with Queen's Quay; from there, there is a free shuttle bus operated by the only airline serving the airport to Union Station, the 509 streetcar is also easily accessible from the airport. The airport does not allow jet aircraft to land or takeoff, the only airline operating commercial flights out of the airport is Porter (http://www.flyporter.com), who run scheduled flights to Montreal, New York City, Quebec City, Halifax and Chicago.
By Streetcar
The 509 LRT streetcar line runs underneath Bay Street from the Union Station subway station to an underground station at the intersection with Queen's Quay West, at which point it leaves the tunnel and proceeds West along Queen's Quay in a separate right-of-way, making stops at the major intersections; its western terminus is Exhibition Place. The 510 LRT streetcar line follows the same route from Union Station to the intersection of Queen's Quay and Spadina Avenue, at which point it turns and heads north on Spadina, still in its own right-of-way, to Spadina subway station at the intersection of Spadina and Bloor Street. The 511 streetcar line runs with traffic along Bathurst Street from Bathurst subway station to the intersection of Bathurst and Fleet Street, where it turns and follows the same route as the 509 West to Exhibition Place.
By car
The Gardiner expressway runs the length of the harbourfront one block north of Queen's Quay and there are exits at Spadina, York, Bay, and Jarvis. There is a large parking garage underneath the Westin Harbour Castle Hotel and several commercial surface lots, including ones at Queen's Quay and York Street, Queen's Quay and Rees Street, on Bay Street across from the Air Canada Centre and on Queen's Quay next to the Redpath sugar refinery.
By Subway And Train
The nearest subway station is Union Station. From there you can either take the 509 or 510 streetcar to Queen's Quay or you can walk south along Bay Street from Front Street, underneath the railway tracks and the Gardiner expressway to Queen's Quay. Union Station is also the main terminus for commuter and intercity trains.
