Start Colon Screening at 45

Summary#

• This bill lowers the starting age for publicly provided colon cancer screening in Ontario to 45. It tells every local public health unit (board of health) to make screening available, including colonoscopies (a test that uses a small camera to look inside the colon).

• The law would take effect three months after it is signed into law.

• Key changes:

  • Makes colon cancer screening available to everyone age 45 and older, not just older age groups.
  • Requires local public health units to ensure screening options are available in their area.
  • States that colonoscopies must be one of the screening options.
  • Does not set how often people should be screened or which test is preferred.
  • Does not spell out funding or new resources.

What it means for you#

• General public (age 45+)

  • You would be able to get colon cancer screening starting at age 45. This could include at-home stool tests or a colonoscopy, depending on what your doctor recommends.
  • You would contact your doctor or local public health unit to learn how to get screened in your area.
  • The bill does not say how often you should be screened. Your doctor will guide you.

• People under 45

  • Nothing changes for you unless you are high-risk and already advised to screen earlier by your doctor.

• Patients waiting for tests

  • More people becoming eligible at 45 may increase demand for colonoscopies and other tests. In some places, wait times could rise unless capacity grows.

• Local public health units (boards of health)

  • You must make sure screening is available to all residents 45 and older. This may involve outreach, distributing test kits, and arranging access to colonoscopies with hospitals and clinics.

• Hospitals and endoscopy clinics

  • You may see higher demand for colonoscopies from people aged 45–49 and others newly seeking screening.

Proponents' View#

• Catching cancer earlier can save lives. Starting at 45 can find growths or cancer sooner, when treatment works best.
• Including colonoscopies ensures people have access to the full range of screening options, not just stool tests.
• Making public health units responsible can improve access and reduce gaps between regions.
• Earlier screening may lower future treatment costs by preventing cancers or catching them at an earlier stage.

Opponents' View#

• Adding a new age group could strain already limited colonoscopy and clinic capacity, leading to longer waits for everyone, including high‑risk or symptomatic patients.
• The bill does not include funding details. Local health units and hospitals may face unfunded costs to expand services.
• Screening more people at average risk may lead to some unnecessary procedures and small risks from colonoscopy (like bleeding).
• The bill leaves key details—such as how often to screen and which test to use—unclear, which may cause uneven rollout across regions.
