Mental health services encompass the programs, facilities, and professionals providing support for mental illness and psychological wellbeing. In Canada, healthcare including mental health is primarily provincial responsibility, but significant service gaps exist. Municipal services often fill these gaps, with police responding to mental health crises, paramedics transporting people in psychiatric emergencies, and municipal programs addressing homelessness with mental health components. The strain on municipal emergency services from mental health calls has prompted many communities to develop specialized crisis response teams, diversion programs, and partnerships with health authorities. Advocates call for better integration between provincial healthcare and municipal services.
