Working as part of a medical team, genetic counsellors provide education and support to families at risk for or diagnosed with inherited conditions. The counsellor can help people understand the pros and cons of genetic testing. They can also help explain which tests may or may not be right for each person. Genetic counsellors can explain test results and how inherited diseases might affect someone or their family.

Genetic counsellors have graduate degrees and experience in the areas of medical genetics and counselling. Many genetic counsellors have worked in other areas, such as nursing, psychology, public health, or social work.

Licensing, certification, and registration requirements for genetic counsellors vary from province to province.
