for Toronto Central and Ontario. Data quality issues
with mortality data preclude the provision of mortality
and PYLL rates at this time. PYLL rates are useful for
quantifying the number of years of life “lost” from
deaths that occur “prematurely” (i.e., before age 75).
Although PYLL rates for Toronto Central are not
provided, Table 4 shows that, provincially, neoplasms
contribute to more years of potential life lost than any
other cause, followed by circulatory system diseases,
and external causes (i.e., injuries). All-cause
hospitalization rates in Toronto Central are lower than
provincial rates as are the cause-specific
hospitalization rates for every ICD-10 chapter with the
exception of chapter seven (e.g., diseases of the eye).
Map 1 shows the 2001 population distribution (mapped

LHIN area. The Toronto Central LHIN includes 44% of
the population of the City of Toronto.
