Skin cancer, including melanoma, is one of the most preventable types of cancer. The main risk factor is UV radiation from sun exposure and other sources, such as indoor tanning beds.

The Ontario Sun Safety Working Group (OSSWG) is a partnership of individuals and organizations working together to reduce the impact of solar and artificial ultraviolet (UV) radiation (including indoor tanning equipment) on human health, such as skin cancer and eye diseases.

  • Raising awareness of the effects of solar and artificial UV radiation on human health

  • Advocating for the development of policy to reduce UV radiation exposure

  • Identifying and developing key information/educational materials related to UV exposure and skin cancer prevention
