Residential Withdrawal Management Services Integration

We are moving our residential and day withdrawal management services, within the neighbourhood, to 333 Sherbourne Street. The University Health Network’s Ossington Men’s Withdrawal Management Centre will also be merging with our program into this location. The new location for our Withdrawal Management Services will be located on the 5th and 6th floors of Sherbourne Health, and it will be operated entirely by St. Michael’s Hospital, Unity Health Toronto.

Construction of the new location began in the fall of 2020 and is expected to conclude within 11-12 months. Construction timelines are occasionally subject to change, and if this occurs, we will provide the updates here.

Why integrate UHN and St. Michael’s services?

University Health Network’s Toronto Western Hospital and Unity Health Toronto’s St. Michael’s Hospital both have a long history of providing detox services in nearby communities. With the aging of each institution’s detox site and the need to provide a safe and supportive environment to this client population, it made sense to integrate existing resources into one site, with oversight from one institution.The decision is supported by the Ministry of Health. The University Health Network will continue to operate its Women’s Own Withdrawal Management Centre.

When this decision was first announced, St. Michael’s Hospital conducted community engagement to ensure that the then proposed location would meet the needs of our stakeholders.

What does this mean to clients?

Residential withdrawal management services are places of rest and recovery that are staffed by sensitive, respectful and well-trained professionals to support clients through their withdrawal process. The community and day withdrawal programs offer structured, day-time withdrawal management programming that is holistic and addresses the clients’ mental health and physical health needs.

Sherbourne Health was selected as the site for our relocated Withdrawal Management Services because Unity Health Toronto already provides services in this neighbourhood, and because it is a central location in downtown Toronto. Further, the large size of the 5th and 6th floors enables us to house all of our withdrawal management services – residential, day and community programs - under one roof.

The new program will include a single point of access for addiction services, aftercare support and a more seamless transition to the community.
