"This Corporate Emergency Plan establishes a command and control structure based on the current TTC chain of command, with the provision for 24-hour a day coverage. The Corporate Emergency Plan has been designed to ensure that all departments who may become involved in an internal large scale or municipal emergency are fully aware of their respective roles and responsibilities. It is intended to be a guide for those who have defined roles and responsibilities during a large scale emergency."
Plan Number 590
