From smallpox hospital to new centre for children and youth with health complexity

The site at Slocan Street and 21 Avenue in Vancouver is one of the oldest locations continually used for health care in the entire province.​

The site will become home to a new centre for children and youth living with health complexity. It has a notable history that we're still learning about.

Indigenous hunting and gathering grounds

The lands south of Burrard Inlet, where the Slocan site is located, were once rich in natural resources. The lands were used by the xʷməθkʷəy̓əm (Musqueam), Sḵwx̱wú7mesh Úxwumixw (Squamish Nation), and səl̓ílwətaʔ (Tsleil-Waututh Nation) for hunting and gathering food, medicine, and resources such as cedar bark, berries, and various roots and shoots. Wood and boughs from native trees such as the Western red cedar and Douglas fir were used as fuel for pit cooking, floor coverings of lodges and sweat lodges, clothing, and as construction materials for house planks, canoes, masks, bentwood boxes, and tools of many kinds.  

Smallpox epidemics

The arrival of European settlers introduced smallpox to B.C. in the late 18th century, with tragic consequences for Indigenous communities. One of the worst smallp​ox epidemics to sweep through B.C. was in 1862, killing one-third of the First Nations population in the province. To learn more about this early history of smallpox, visit the First Nations Health Authority website.

To deal with the smallpox epidemics, a preliminary isolation hospital with 12 beds was built on Keefer Street in Vancouver. But by 1909, with the arrival of more settlers, there was a need to expand. 

Many residents objected to a new isolation hospital within city limits. So in 1911, a location was purchased for $45,000 at Slocan Street and 21 Avenue in Hastings Townsite, then a separate municipality in the process of being annexed by the City of Vancouver.

1912: The isolation hospital opens

The isolation hospital took just over one year to build. It had an administrative building and two wards: a smaller ward for women and a larger ward for men. The front entrance included a mortuary.

1920s: Vaccination campaigns

During the 1920s, a series of vaccination campaigns helped curb successive waves of the disease. For example, a 1920 smallpox outbreak led to 80 per cent of school-aged children being vaccinated in just six months.

1930s: From smallpox to tuberculosis

By the early 1930s, the isolation hospital fell out of use due to a decline in smallpox (the disease was officially declared as eradicated in 1980 by the World Health Organization, as a direct result of global vaccination). 

The buildings on the Slocan site were repurposed into a tuberculosis (TB) preventorium for children, which opened in 1931.

In the 1940s and 1950s, the preventorium treated children from all over the province for TB and polio, the major health issues of this time. ​

1958: A royal visit​​

1961: The beginnings of Sunny Hill

1961_Slocan_SunnyHillHospital_web.jpgWith the success of antibiotics in treating TB, preventoriums were no longer needed. In 1961, the site was renamed the Sunny Hill Hospital for Children. It focused on caring for kids with cerebral palsy, disabilities, and children requiring extensive rehabilitation.

2020: A new vision for the site

In August 2020, Sunny Hill moved to the BC Children’s Hospital Oak Street campus, into a brand new, state-of-the-art facility​.

The former Sunny Hill building will be demolished to make way for a new centre for children and youth living with health complexity – continuing the century-old legacy of health care on this site.

The new centre and service will be the first of its kind in Canada in how it coordinates care for these children and their families as their needs change. Learn more about the proposed services.

Meet the Slocan project team July 10 & August 21

Members of the project team working on the new services and centre will be out in the community this summer.
