1. Data sources: Statistics Canada, Canadian Cancer Registry Database and Demography Division (population estimates)
2. World Health Organization, International Classification of Diseases, 9th Revision (ICD-9)
3. Cancer incidence refers to new primary sites of malignant neoplasms.
4. Cancer incidence rates are age-standardized using the direct method and the 1991 Canadian Census population structure. The use of a standard population results in more meaningful incidence rate comparisons, because it adjusts for variations in population age distributions over time and across geographic areas.
5. Rates in this table are based on three consecutive years of cancer incidence data which were summed and divided by three times the population estimate of the middle year of the three-year period.
6. The confidence intervals for the age-standardized cancer incidence rates were produced using the Spiegelman method. Reference: Spiegelman M. "Introduction to Demography", Revised Edition. Cambridge, Massachusetts: Harvard University Press, 1968, p 113, Formula 4.29.
7. The 95% confidence interval (CI) illustrates the degree of variability associated with a rate. Wide confidence intervals indicate high variability, thus, these rates should be interpreted and compared with due caution.
8. Some age-standardized rates were suppressed (F) due to both a very small underlying count plus extremely high variability.
9. "Health regions" are defined by the provincial ministries of health. These are legislated administrative areas in all provinces except Nova Scotia.
10. In Nova Scotia, the Ministry of Health uses statistical "zones" rather than its legislated administrative areas; the zones are aggregations of the nine district health authorities.
11. For complete Canadian coverage, each of the northern territories also represents a health region.
12. The health regions presented in this table are based on boundaries and names in effect as of April 1, 2003.
13. In Manitoba, Saskatchewan and Alberta, health regions are referred to as Health Authorities (HA) or Regional Health Authorities (RHA).
14. Cancer incidence data for health regions have been suppressed at the request of the cancer registries of the following provinces: Prince Edward Island, New Brunswick and Ontario.
15. Cancer incidence data for the three northern health regions in Quebec (2410 Région du Nord-du-Québec, 2417 Région du Nunavik and 2418 Région des Terres-Cries-de-la-Baie-James) have been suppressed at the request of the Fichier des tumeurs du Québec.
16. Over 6% of Ontario cancer incidence records over the 3-year period could not be linked to health region geography. As such, cancer incidence data for Ontario are only published at the provincial level.
17. The following symbols are used in Statistics Canada publications: (..) for figures not available, (...) for figures not appropriate or not applicable, and (x) for figures suppressed for the confidentiality provisions of the Statistics Act.
18. CANSIM table number 01030203.
