When viewed from above, the Council Chamber, positioned between the two curved towers of City Hall, resembles an eye between two eyelids.

It is 46 metres wide and 12 metres at its highest point. It is supported solely by a circular column below. The roof is supported by 23 pairs of v-shaped concrete struts located outside the windows.

The ceiling, which weighs over 2000 tonnes, was made by pouring concrete into a single plywood mould. It took 40 days for the concrete to dry.

To absorb sound, the Council Chamber is carpeted and the ceiling is sprayed with a carpet fibre.

Official meetings of Toronto City Council are held in the Council Chamber. Council meetings commence on the fourth Tuesday of each month and generally last for three days. Each day's session runs from 9:30 a.m. to approximately 6 p.m. For more details, please check the schedule of Council meetings, available online.

The general public is welcome to attend City Council meetings. The public seating gallery can accommodate as many as 250 people at any given time. Speakers installed in front of seats in the public gallery make it easy for the audience to follow the debate.

When he is chairing a City Council meeting, the Mayor sits in the centre chair located directly below the City of Toronto logo. The 44 City Councillors occupy the horseshoe-shaped seating area facing him. Seating assignments for individual members of Council are determined by lot.

The City Clerk, who provides administrative support for Council, sits with staff at a table in the middle of the horseshoe, directly in front of the Mayor. Commissioners (i.e., department heads) sit to the left and right of the Mayor.

A seating area for the City Hall press is situated behind the public gallery at the back of the Council Chamber.

The Members' Lounge, located behind the Council Chamber, provides City Councillors with a place to hold informal discussions and is also used as a venue for official receptions.

The Members' Lounge overlooks Nathan Phillips Square and also provides an excellent view of the Green Roofs Demonstration Project, featuring eight accessible garden plots on the podium roof at Toronto City Hall.
