Residential Withdrawal Management Services Integration

St. Michael’s Hospital and University Health Network are bringing their Residential Withdrawal Management Services (WMS) under one roof. Residential WMS assist clients with voluntary withdrawal from alcohol or other substances.

The proposed location for this integrated program is the Sherbourne Health Centre, located at 333 Sherbourne St. The new location will be operated by St. Michael’s Hospital.

Why integrate UHN and St. Michael’s services?

The existing WMS sites at 16 Ossington Ave. (UHN) and 135 Sherbourne St. (St. Michael’s) are inadequate for today’s best practices and standards. Therefore, part of the voluntary integration has been to find a single site that can accommodate 36 beds in a welcoming and therapeutic environment. We believe that we have found that location: Sherbourne Health Centre.

Sherbourne Health and St. Michael’s have signed a letter of intent that will allow St. Michael’s to renovate the unused fifth and sixth floors at 333 Sherbourne St. for this use. Before we work with TC LHIN to formalize our voluntary integration, we are conducting community engagement to make sure that the proposed location will meet the needs of our stakeholders.

When will the services integrate and move to the new site?

The implementation planning and consultation for integration are underway, guided by the TC LHIN Voluntary Integration Act.

In the meantime, both sites will remain active until the move to one site occurs.

What does this mean to clients?

The integration of the two programs will better meet the goals of the population served, and contribute to a more effective Toronto Central Local Health Integration Network (TC LHIN) withdrawal management and addictions system. We see this as a great opportunity to design a modern, much improved space that will be more conducive to a comprehensive withdrawal management program. The new program will include a single point of access for addiction services, aftercare support and a more seamless transition to the community.
