CCO SEER*Stat Package

The Ontario Cancer Registry SEER*Stat Package contains de-identified Ontario cancer data files derived from the Ontario Cancer Registry, the SEER*Stat software and supporting user documentation. This package allows analysts to produce incidence, mortality, survival and prevalence statistics for studying the impact of cancer on the Ontario population.

Statistics produced by the Ontario Cancer Registry SEER*Stat Package are useful for:

  • cancer prevention and control
  • understanding health disparities
  • prioritizing cancer control efforts
  • monitoring progress, for the purpose of reducing the burden of cancer

For more information see Surveillance Program or connect with us by email at

Data Files

The Ontario cancer data files contain incidence and mortality data for the following levels of geography: Ontario, Census Divisions, Public Health Units (PHUs), and Local Health Integration Networks (LHINs). For the most recent release (Release 11, June 2019), here is more detailed information:

  • The Ontario cancer data files contain incidence and mortality data, from the years 1981 to 2016. 
  • Beginning with 2010 diagnoses, the Ontario Cancer Registry adopted the SEER Multiple Primary and Histology Coding Rules for counting additional primary cancers. As a result, there is an increase in the number of new cases compared to pre-2010 incidence counts. This change in number is due to how cancers are being counted; it does not mean that more people in Ontario are being diagnosed with cancer — see How We Collect Cancer Registry Data for more information. 
  • To align with Statistics Canada’s update of the standard reference population (from 1991 to 2011) for age-standardization, we are offering data users the 2011 Canadian standard population as an option (among others) in this release. For more information, see Change to Reference Population.

To learn more about the SEER*Stat software, please visit the U.S. National Cancer Institute's SEER*Stat Software website.

The Package is available to requestors in Canada who are employees of public health units, research institutions, government and government agencies for the purpose of health planning, management or research.
