gcConnect: Connecting Clinicians to Genetics Expertise

gcConnect supports Ontario clinicians navigating genetic testing and services in Ontario.

This province-wide clinician support service is delivered through a network of genetic counsellors. It aims to:

  • expand access to genetic testing by supporting non-genetics clinicians in ordering tests within their scope of practice
  • build skills and knowledge through targeted education and training
  • provide real-time support by phone and email, connecting clinicians directly with a genetic counsellor

gcConnect genetic counsellors do not provide clinical care for patients. gcConnect does not offer medical advice, assumes no responsibility for patient decisions rendered, and is not part of the circle of care for any patients. Please do not share personal information or personal health information with our team. Instead, consider a referral to genetics or an e-consultation through OTNhub.

To find a local genetics clinic where genetic counselling is provided, visit Ontario Genetics Clinic Directory.

gcConnect Regional Education Program

Genetic counsellors from our regional partner sites offer educational talks and training tailored to non-genetics clinicians, with a focus on Ontario Health’s genetics guidance documents.

To inquire about genetics education for a clinician group, please send us an email.

Order Genetic Testing as a Non-Genetics Clinician

In some cases, non-genetics professionals may need to order genetic testing. Clinicians should decide if the services are within their scope or if they should refer to a specialist.

Use the gcConnect Resource Line to discuss a specific situation. Find referral guidance documents for some conditions at Genetics Guidance.
