Ontario has 31 professionals from 15 Ontario cities qualified as Registered Sex Therapists with the Board of Examiners in Sex Therapy and Counselling in Ontario (BESTCO) . Their membership is multidisciplinary and includes professionals from: the Ontario Psychological Association, the College of Physicians and Surgeons, the College of Nurses, the College of Certified Social Workers and The Registry of Marriage & Family Therapists in Canada (Clinical Member AAMFT). Note that some of the members listed below are also BESTCO members.

The following list of resources includes therapists and physicians that provide sex therapy. If you are looking for a therapist with specific training in sexual addiction and compulsivity look for the Certified Sex Addiction Therapist (CSAT).

Other, equally qualified, sex therapists include those registered as sexologists (ABS Certified, AASECT or American College of Sexologists). Note, however, that these associations include sexuality educators, sex counsellors and sex therapists.  Individuals seeking therapy are recommended to contact the provider directly to ensure that therapy, and not education, is provided.
