Community Mental Health Common Assessment Project

What is OCAN?

The Ontario Common Assessment of Need (OCAN) is a standardized, consumer-led, decision-making tool that assists with mental health recovery. 


OCAN’s collaborative, holistic approach to supporting mental health recovery is built around internationally recognized research. Strongly supported by the Ontario Mental Health sector, OCAN captures the consumer’s voice by:


·          Identifying individual needs

·          Matching these needs to existing services

·          Highlighting service gaps

OCAN is designed to:


Benefit both consumers and HSPs by:

  • Enabling consumer-led decision making at an individual level
  • Reducing repetitive information gathering
  • Standardizing, streamlining and unifying assessment
  • Providing an aggregate view of the sector to support informed decision making

Current Status

The implementation phase of OCAN occurred between 2009 – 2012. In 2013, CMH CAP transitioned to an operational phase where the provinicial common assessment and integrated assessment record advisory committee continues to engage with the CMH sector to sustain the use of OCAN in compliance with provincial standards. Health Service Providers (HSPs) are experiencing the value of incorporating OCAN to support client care.
