to increase efficiency and reliability, and the addition of acid gas control equipment to all eight units. By 1992, only four units had been overhauled when repairs were halted due to the changing future outlook and to a decline in the consumer use of energy, due to economic recession. 1993–2000: In January, 1993, reduced load forecasts resulted in the decommissioning of Units 3, 4, 7 and 8. In 1994, the plant returned to service as a four-unit peak-demand generating station, but with a much improved environmental performance. Lakeview continued to provide customers with a safe, reliable source of power when demand was highest, and became a key asset in times of uncertainty in the electricity marketplace. The station's location in the GTA made its output invaluable to some of Ontario's largest municipal utilities and industries –especially when nuclear and other generation was not available. 1998–2002: In December, 1998, Ontario Hydro announced a joint venture to pursue the development of a 550 MW natural gas-fired combined cycle power plant at Lakeview. The venture was dissolved in May, 2000. In March, 2001, the provincial government announced that Lakeview would be required to stop burning coal by April, 2005. 2003–2005: In October, 2003, the provincial government confirmed that Lakeview would close on April 30, 2005, with plans for the remainder of OPG's coal-fuelled plants removed from service by the end of 2007; this plan never met its deadline and only the Lakeview plant was demolished before 2008. June 12, 2006: "The Four Sisters" were successfully imploded by Murray Demolition LP, in order of east to west, falling to the east with a stack toppling every 4 seconds. Over a thousand spectators came to a nearby park to observe the demolition. Helicopters filled the sky, each taking footage of the event. June 28, 2007: The rest of the building was demolished at 11:04am EST.
