Cancer deaths data are derived from the Ontario Cancer Registry (OCR) operated by Cancer Care Ontario. The OCR contains information on Ontario residents who have died of all types of malignant cancers. Cancer sites were coded using the Third Edition of the International Classification of Diseases for Oncology (ICDO-3).
This HealthSTATS page only includes deaths from malignant melanomas of the skin. Non-epithelial skin cancers, which are not included in these statistics, represent approximately 25% of skin cancer deaths that are tracked by the OCR. These statistics also do not include data for basal cell and squamous cell carcinomas, which are not tracked by the OCR. Exposure to ultraviolet (UV) rays is the most important risk factor for malignant melanomas. Sunlight is the main source of UV rays. Tanning beds and sun lamps are also sources of UV rays.
Overall
In Simcoe Muskoka from 2010 to 2018, 232 residents died from malignant melanomas of the skin (for an average of approximately 25 per year) for an age-standardized mortality rate of 4.2 (3.7, 4.8) deaths per 100,000 population. This was significantly higher than the Ontario malignant melanoma mortality rate of 3.3 (3.2, 3.4) deaths per 100,000.
The chart below shows the trend in malignant melanoma mortality in both Simcoe Muskoka and Ontario from 1986 to 2018, grouped into four distinct periods of time. Neither the Ontario nor the Simcoe Muskoka rates have changed significantly since 1994. The Simcoe Muskoka rates have been significantly higher than the provincial rates since 1994.

By Sex
Over the nine years between 2010 and 2018, the age-standardized mortality rate for malignant melanoma among Simcoe Muskoka males was 6.4 (5.4, 7.5) deaths per 100,000, which was significantly higher than the female rate of 2.4 (1.9, 3.1) deaths per 100,000. The comparable age-standardized malignant melanoma mortality rate for Ontario males was significantly lower than what was observed in Simcoe Muskoka; however the provincial female rate was not significantly different from the comparable Simcoe Muskoka rate.
The chart below shows the trend in malignant melanoma mortality rates for males and females in Simcoe Muskoka between 1986 and 2018, grouped into four distinct time periods. The malignant melanoma mortality rates among Simcoe Muskoka males for both the 2002-2009 and 2010-2018 time periods were significantly higher than the rate for the 1986-1993 period. The malignant melanoma mortality rates among Simcoe Muskoka females did not change significantly across time. The Simcoe Muskoka male rates have been significantly higher than the comparable female rates for the entire time.

By Age Group
Malignant melanoma mortality increases significantly with age. The age-specific malignant melanoma mortality rates between 2010 and 2018 (combined) in Simcoe Muskoka were highest among those 75 years and older at 30 (24.8, 36.4) deaths per 100,000 population, which was more than eight times the rate among adults 45 to 64 years of age and double the rate for adults between 65 and 74 years of age. The age-specific malignant melanoma mortality rate in Simcoe Muskoka was significantly higher than the comparable provincial rate among seniors 75 years of age and older.
