Advancing public mental health in Canada through a National Suicide Prevention Service: Setting an agenda for Canadian standards of excellence

The Public Health Agency of Canada is funding a new Canada Suicide Prevention Service (CSPS), timely both in recognition of the need for a public health approach to suicide prevention, and also in the context of the COVID-19 pandemic, which is causing concern about the potential for increases in suicide. This editorial reviews priorities for suicide prevention in Canada, in relation to the evidence for crisis line services, and current international best practices in the implementation of crisis lines; in particular, the CSPS recognizes the importance of being guided by existing evidence as well as the opportunity to contribute to evidence, to lead innovation in suicide prevention, and to involve communities and people with lived experience in suicide prevention efforts.
