Who do I call, when and how?

As part of the WWRCP we offer care around the Waterloo Wellington Region. This means that you might have some, or part of your care at our regional site (Grand River Regional Cancer Centre) but other parts of your care or treatment closer to your home in Cambridge, Guelph, Mt. Forest, Palmerston or Fergus.

Please note that your Oncology Nurse and Oncologist (cancer doctor) are often very busy during the day and will not always be free to take your call. If you are calling in you will often need to leave a message with the call centre. If you have an urgent message please stay on the line when you call.

If you have a medical emergency go to your closest Emergency Department.

Calling in After Hours


CareChart (CareChart@home), a subsidiary of Bayshore HealthCare Ltd., is an after-hours virtual support program for patients going through cancer treatment.

Sponsored by Ontario Health (Cancer Care Ontario), this program offers symptom management support for cancer patients who are going through treatment when their local treatment centre is closed. You can talk with a Registered Oncology Nurse. All reports are shared with the patient’s treatment facility, allowing for timely follow-up support from their treatment team if needed.

Between their cancer treatment centre and CareChart, patients have access to 24-hour care, 365 days a year to help them manage their symptoms while remaining at home.
