Cancer Care Ontario (CCO) monitors cancer incidence, mortality and survival patterns, as well as trends over time, place (e.g., by Local Health Integration Network or Public Health Unit) and person (e.g., by age group or sex).
This information is reported publicly through the Cancer System Quality Index, and through cancer monographs and peer-reviewed publications. Some cancer data are also available in an aggregated form, without interpretation, upon request.
We do this work using data stored in the Ontario Cancer Registry, which includes information about all newly diagnosed cases of cancer in Ontario since 1964. The Ontario Cancer Registry is operated by CCO under the authority of the Cancer Act of Ontario and the Personal Health Information Protection Act (PHIPA) of Ontario.
The tables below provide statistical information about the geographic patterns of cancer incidence and deaths in Ontario for 2004, the most recent year for which the Ontario Cancer Registry has received complete data.
New cases and deaths for all cancers, 2004: Geographic patterns of cancer in Ontario
Incidence rates for all cancers combined were 440.3 per 100,000 in males and 343.6 per 100,000 in females in Ontario. Overall cancer incidence rates were highest in Erie St. Clair Local Health Integration Network (LHIN) for males (516.6 per 100,000) and in North East for females (377.4 per 100,000). Incidence rates were lowest in Toronto Central for males and Central West for females.

Mortality rates for all cancers combined in Ontario were 195.6 per 100,000 in males and 139.0 per 100,000 in females. Overall cancer mortality rates were highest in the North East for males (237.1 per 100,000) and females (160.4 per 100,000). Lowest rates were in Central West for both sexes.

The prostate cancer incidence rate was 127.6 per 100,000 in Ontario and was highest in Erie St. Clair (156.6 per 100,000). The breast cancer incidence rate in Ontario was 95.6 per 100,000 and was highest in Hamilton Niagara Haldimand Brant (103.1 per 100,000). The mortality rates were 21.9 per 100,000 for prostate and 23.2 per 100,000 for breast cancer in Ontario. Mortality rates were highest in North West for prostate cancer (36.6 per 100,000) and Erie St. Clair for breast cancer (28.0 per 100,000).
Lung cancer incidence rates were 59.0 per 100,000 for males and 40.9 per 100,000 for females in Ontario. Incidence and mortality rates in males were high in Erie St. Clair, South East, and North East LHINs. Incidence rates in females were high in South East, North Simcoe Muskoka, and North East and mortality rates were high in South East, North East, and North West LHINs. In men, the incidence rate was lowest in Mississauga Halton LHIN and the mortality rate was lowest in Central LHIN. Both incidence and mortality rates were lowest in Central West LHIN in women.
The incidence rate of colorectal cancer was 58.6 per 100,000 in males and 40.2 per 100,000 in females in Ontario. Colorectal cancer incidence rates were highest in North East at 72.7 per 100,000 in males and 48.8 per 100,000 in females. Mortality rates were 24.7 per 100,000 in males and 16.4 per 100,000 in females in Ontario. Highest mortality rates were in North Simcoe Muskoka for males (32.0 per 100,000) and South East for females (20.8 per 100,000). Lowest incidence and mortality rates were in Central West for both sexes.
