On January 1, 2023, the province of Ontario lowered the colorectal cancer screening age from 50 to 45, in an effort to catch the disease earlier and improve treatment outcomes. According to Dr. Catherine Labreche, a gastroenterologist at Toronto General Hospital, “It challenged previous assumptions about the age at which colorectal cancer typically develops, and we’re hoping this change will lead to more people getting screened and diagnosed earlier.” The move comes after a review of data showing that the incidence of colorectal cancer is increasing in younger adults. In 2020, over 26,000 Canadians were diagnosed with colorectal cancer, resulting in more than 9,000 deaths.
The decision to lower the screening age is expected to cost the provincial healthcare system an additional $10 million annually, but health officials believe it will ultimately save lives and reduce healthcare costs in the long run. As Ontario’s colorectal cancer screening program expands to include more people, other provinces are watching closely, considering whether to follow suit. British Columbia and Alberta are already reviewing their own screening guidelines, with announcements expected in the coming months.

In the United States, the American Cancer Society recommends that adults with an average risk of colorectal cancer start regular screening at age 45. Canadian provinces are under pressure to align their guidelines with this recommendation. The Canadian Cancer Society estimates that by 2025, over 28,000 Canadians will be diagnosed with colorectal cancer each year, with the disease claiming over 10,000 lives annually.
As more provinces consider lowering the colorectal cancer screening age, the impact on healthcare systems and patient outcomes will be closely monitored. One key factor to watch is the availability of screening resources, including colonoscopy services and fecal occult blood tests. A study published in the Canadian Journal of Gastroenterology found that expanding screening programs to include more people could prevent up to 500 colon cancer deaths per year in Canada.
Ontario’s move to lower the screening age is a step in the right direction, but it remains to be seen how other provinces will respond and what the long-term effects will be on colorectal cancer diagnosis and treatment rates. Readers should watch for updates from their local health authorities and consider speaking with their healthcare provider about screening options. The province will review the effectiveness of the new screening age and may adjust its guidelines further based on the results.
