The Harbourfront neighbourhood in Toronto encompasses the area from the lakeshore corridor railway line in the north down to Lake Ontario in the south and from Exhibition Place in the west to Parliament Street in the east. Nearly the entire neighbourhood is built on land reclaimed from Lake Ontario in the nineteenth and twentieth centuries. Prior to the 1980s, the area was largely industrial, especially the section south of the Gardiner expressway, which was built in the 1930s and acted as a barrier to development until the 1980s, when a lack of available space downtown led property developers to start building large condominium developments in the Harbourfront neighbourhood. Queen's Quay acts as the main street for the neighbourhood, containing an abundance of fast-food restaurants and convenience stores. Most of the shopping is in Queen's Quay Terminal, a large shopping and condo development which acts as something of a central point for the neighbourhood. On the south side of Queen's Quay is a series of slips separating large piers containing a mixture of condo towers, repurposed warehouses and small parks. In the summer, the neighbourhood is a buzz of activity with small concerts and festivals occurring in the park. While the area west of Yonge Street is full of high rise condo developments and activity at all hours, the area east of Yonge Street remains nearly entirely undeveloped and consists of a series of small, largely abandoned warehouses and empty lots, as well as the enormous Redpath sugar refinery; despite this, there is a large Loblaws supermarket and a concert hall known as Kool Haus at the intersection of Queen's Quay and Jarvis Street.
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.
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.

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.
The Toronto City Centre Airport  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 , who run scheduled flights to Montreal, New York City, Quebec City, Halifax and Chicago.
