The Gooderham Building, also known as the Flatiron Building, is an historic office building at 49 Wellington Street East in Toronto, Ontario, Canada. It is located on the eastern edge of the city's Financial District in the St. Lawrence neighbourhood, wedged between Front Street and Wellington Street in Downtown Toronto, where they join up to form a triangular intersection. Completed in 1892, the red-brick edifice was an early example of a prominent flatiron building.

St. Lawrence is a neighbourhood located in downtown Toronto, Ontario, Canada. The area, a former industrial area, is bounded by Yonge, Front, and Parliament Streets, and the Canadian National railway embankment. The Esplanade off Yonge St., lined with restaurants, cafés and hotels runs through the middle of the area. In previous times, the area was sometimes referred to as 'St. Lawrence Ward' or more often today as 'St. Lawrence Market', synonymous with the large retail vendor market which is the neighbourhood's focal point. The area is the site of a large city-sponsored housing project of the 1970s, which revitalized an old brownfields area. The boundaries of the St Lawrence Neighbourhood Association and the St Lawrence Market BIA are somewhat larger than those noted above. Both groups have boundaries that extend from Yonge to Parliament Streets and Queen Street East to the rail corridor.
