Shattering balcony glass has pushed Toronto apartment owners to launch class-action suits against developers, contractors and others, alleging negligence in the construction of two condo developments in which glass crashed to the streets below. As a result, the balconies were sealed months ago and residents denied access to them. The action on behalf of owners and renters of the units in the Murano Towers, located on Bay Street near College Street, names Bay Grenville Properties and Lanterra Developments, among others.
