Cancer Care Ontario, a provincial cancer agency in Canada, has compiled more than 30 years of data from the Ontario Cancer Registry to produce the Ontario Cancer Statistics 2016 report.

In this first comprehensive look at the state of cancer in Ontario, OCS 2016 provides a clear picture of cancer, focusing on the incidence, mortality, survival and prevalence of the disease in Canada’s largest province.

For the first time, statistics on clinically relevant indicators for select cancers, using stage at diagnosis, cancer histology and biomarker data are also reported.

ocsreport2016_coverpage_jm01-232x300Highlights from the report were presented at the NAACCR 2016 Annual Conference and include:

  • One in two Ontarians will develop cancer in their lifetime and one in four will die from it;
  • Approximately 85,648 new cases of cancer are expected to be diagnosed in Ontario in 2016, which is almost triple the number of cases that were diagnosed in 1981 (29,649 cases), largely attributed to an aging population and population growth;
  • Cancer mortality rates are declining and survival for nearly all cancer types is increasing in the province;
  • The five-year relative survival ratio for all cancers combined in Ontario is 63 per cent;
  • There are now more people living in Ontario with a diagnosis of cancer than there were 20 years ago—an estimated 362,557 people as of January 1, 2013 (or about 2.7 per cent of the Ontario population).

OCS 2016 is a definitive source for cancer surveillance information for Ontario and is expected to be published every two years.

Ontario Cancer Statistics 2016 is a report that comprehensively describes the burden of cancer in Ontario. It uses data from the Ontario Cancer Registry to provide a clear picture of cancer in this province, focusing on the incidence, mortality, relative survival and prevalence of this disease. This information is intended to support decision-makers, the public health community, healthcare providers, researchers and others in planning, investigating, measuring and monitoring population-based cancer control efforts.

The report is comprised of five key chapters that can be downloaded individually. Also available for use is an infographic summary of the key report highlights and pre-populated PowerPoint slides with figures from the report.
