This article provides estimates of the reported level of colorectal cancer (CRC) testing in the Canadian population aged 50 or older in 2008.
The data are from the 2008 Canadian Community Health Survey. With weighted data, the percentage of people who had undergone CRC testing (fecal occult blood test in the past two years or endoscopy within the past five years) was estimated. Bivariate and multivariate analyses were used to examine testing status in relation to personal, socio-economic and other health-related characteristics.
In 2008, an estimated 40% of Canadians aged 50 or older reported that they had had CRC testing. The percentage ranged from 28% in Quebec to 53% in Manitoba. Testing was associated with being 65 or older, higher income, having a regular doctor, being a non-smoker, and being physically active.
Organized CRC screening was limited in 2008, but may account for some of the differences in participation among the provinces.

As a group, cancers of the colon and rectum constitute the third most common cancer in Canadian adults. An estimated 22,000 new cases were diagnosed in 2008–about one in eight of all new cancers that year. Approximately 94% of colorectal cancers (CRC) are diagnosed in people aged 50 or older.
