St. Lawrence Hall 1850
Erected in 1850 this structure provided a grand public hall in the St. Lawrence market-place, then the centre of Toronto, for concerts, balls, meetings and other civic events. Seating a thousand, it was proudly regarded as one of the city's finest buildings. Here Jenny Lind sang, the Anti-Slavery Society met, and George Brown addressed ardent Reform gatherings before Confederation. When the centre of the city shifted north and west in the 1870's, St. Lawrence Hall's great era ended.
