After residents were forced to evacuate a Toronto neighborhood when the Sunrise Propane Industrial Gases plant exploded, Toronto's mayor is launching a review of all areas that could threaten neighboring homes in a similar situation. Toronto residents have expressed anger that the plant was allowed to operate so near to a neighborhood that is home to more than 12,000.

"I've asked city officials to provide me with an analysis and recommendations on what the city of Toronto can do through our zoning power in order to ensure our neighborhoods are safe and remain safe when a business such as this operates within the city," Mayor David Miller told the Associated Press.
