Cancer Care Ontario provides access to the Ontario Cancer Registry through SEERStat software (Release [6.6.2] February, 2011). The Registry is a database of information on all Ontario residents who have been newly diagnosed with cancer (incidence) or who have died of cancer (mortality). The Registry is populated from four main data sources: hospital discharges and emergency care, pathology reports, regional cancer centre records, and death certificates. All new cancer cases are registered, with the exception of non-melanoma skin cancer.

Ozone (O3) is created when nitrogen oxides and volatile organic compounds combine in the presence of sunlight. High ozone occurs primarily in the summer, though over time levels of ozone are also increasing in the winter in Southern Ontario. Ozone is associated with adverse effects on respiratory symptoms and lung function. http://airqualityontario.com/press/faq.php
