BCPFFA. Whitehorse Fire Department is the largest municipal fire department in the territory and the only professional one. Though they are 13% of the total population of firefighters in the territory, WHFD protects 82% of the population, and responds to 84% of fire calls within the Yukon. WHFD falls under the authority of the Yukon Fire Marshals Office (FMO) and reports directly to it. Fire and life safety inspection throughout the City of Whitehorse are conducted by the Whitehorse Fire Department duty crews as well as designated Fire Prevention Officers under the direction of Municipal Bylaw 2000–01 "Emergency Services Bylaw" with authority from the current edition of the National Fire Code of Canada. Wildland fire crews also operate in the summer to combat the forest fires across the territory. They will lend assistance to crews in B.C., Alberta, and the other territories as needed. Energy grid Yukon Energy operates four conventional hydroelectric generating stations: Whitehorse Dam (40 MW), Aishihik Lake (37 MW), Mayo A (5 MW), and Mayo B (10 MW), which provide the bulk of generation for the Yukon Energy grid. An additional 39 MW of diesel generation is maintained for supplemental back-up. Additionally, Yukon Energy operates two wind turbines near Whitehorse, which are connected to the Whitehorse-Aishihik-Faro grid. The first turbine is a Bonus Energy 150 kW MARK III installed in 1993 that is no longer functional. The second turbine, a Vestas 660 kW V47 LT II was later installed in 2000 and operates only in the summer. These units need to be specially adapted to deal with icing and the northern environment. Health care The first "White Horse General Hospital" (WGH) was built in the downtown area in 1902 with a 10-bed capacity. During World War I beds increased to 30, 10 beds were added in 1943, then 20 beds in 1949, and an operating wing was added in 1951. In 1959 the hospital was rebuilt on the other bank of the Yukon River, across from its previous location, but decision making was still based in Ottawa (National Health and Welfare, Medical Services Branch). The downtown area has several private medical, dental, and optometry clinics. In 1990, the Yukon Hospital Corporation (YHC) was created in order to prepare the transfer of powers regarding the hospital from the Federal Government to the Yukon Territorial Government. In April 1993 management of WGH was officially transferred to the YHC following
