Another glass balcony has shattered in a downtown Toronto condominium complex, slightly injuring a woman.

Glass fell from the balcony on the 31st floor of the south tower around noon Monday. There have been five such recent incidents at the twin tower Murano complex near Grosvenor and Bay streets, but the others have involved the north tower.

One lane of Bay Street has been closed as police, the provincial Ministry of Labour, the developer and the contractor investigate.

Police say a 28-year-old woman suffered minor injuries to her hand when she was struck by a piece of the falling glass.

The glass balcony partitions were installed at the Murano complex in 2009 and at least nine of them have shattered since December 2010. They were made by a company that has since gone out of business, according to the developer, Lanterra Developments.

After two panes fell in late July, the city ordered Lanterra to remove the balcony glass from the north tower because the situation was deemed unsafe for people in and around the structure.
