As part of their role, the Behavioural Support Transition Units (BSTU) Collaborative conducts an environmental scan of Ontario’s BSTUs on a regular basis. The objective of these scans is to offer an overview of the current state of BSTUs in Ontario. The information gathered through this scan enhances the collective understanding of the BSTU landscape, identifies quality improvement activities, and informs future planning for BSTUs in Ontario. The most recent environmental scan was released in September 2023.
