Dr. Du Bois’ retirement -notice of Practice Closure

Update for Dr. Du Bois' patients - November 2025

As of Oct 1, 2025, all of Dr. Du Bois’ previous patients have been formally de-rostered from Dr. Du Bois by the Ministry of Health (MOH).  A portion of these patients, especially those with high needs, have been reabsorbed back into the Limestone FHO group by other doctors.  Due to capacity limitations, we were unable to re-attach all patients back to our clinics.

However, please do not lose hope.  I urge you to enroll with Health Care Connect (register at 1-800-445-1822 or online at www.ontario.ca/healthcareconnect), so that you can re-connect with a new family doctor.  Currently, HCC is working hard together with our Ontario Health Team (FLA-OHT) to actively place unattached patients with doctors accepting patients in the Kingston and surrounding areas.  Our FLA-OHT is on track to enroll thousands of patients in the upcoming year.

Limestone FHO has also acquired two new doctors, who also will be enrolling patients from Health Care Connect in the Spring of 2026.  Therefore it is imperative that you register with Health Care Connect to be considered for future attachment to a new doctor in your region.
