Canadian Cancer Registry (CCR)
Summary of changes
Activity on this program started: 1992
As of 2007, the CCR adopted SEER Multiple Primary Histology rules for determining multiple primaries. Some differences in incidence between the years 2006 and 2007 may be attributed to this change. As well, due to technical issues in updating systems to adhere to these new rules, not all registries were able to report according to the new requirements for 2007. This may result in inconsistencies between provinces and territories.
In 2006, the CCR Redesign project was undertaken to migrate the old system from the Statistics Canada mainframe platform to a UNIX server environment. The Canadian Cancer Registry now includes new diagnostic variables as well as staging variables.
History of the Canadian Cancer Registry (prior to the 1998 reference period):
The person-oriented Canadian Cancer Registry (CCR) evolved from the event-oriented National Cancer Incidence Reporting System (NCIRS).
Beginning with reference year 1992, the CCR replaced the NCIRS as Statistics Canada's vehicle for collecting information about cancer across the country. All Canadian provincial and territorial cancer registries now report their data to the CCR.
The NCIRS was established in 1969 at Statistics Canada in co-operation with the National Cancer Institute of Canada and nine of the ten existing provincial cancer registries. A tenth registry, Ontario, joined the national system in 1981.
