Our History

A majority of Niagara hospitals were given direction by Ontario’s Health Services Restructuring Commission to amalgamate in 1999. In March 2000, the Niagara Health System was created as a full amalgamation of 8 hospitals – 3 large community hospitals, 3 smaller rural hospitals, 1 specialty complex care hospital and 1 outpatient rehabilitation centre. This complex merger, including boards of trustees, has resulted in many levels of integration in infrastructure and programs as our network works together in the provision of services.

In November 2004, new directions were issued by the Province that the Niagara Health System would be the sole provider of acute inpatient care for most of Niagara. As a result, the former Hotel Dieu Health Sciences Hospital, Niagara was placed under governance and management of the NHS in August 2005. This St. Catharines hospital has been renamed the Ontario Street Site. At the same time, Shaver Hospital and Niagara Rehabilitation Centre were placed under the governance and management of Hotel Dieu and the Religious Hospitallers of St. Joseph, and renamed Hotel Dieu Shaver Health and Rehabilitation Centre.

The new St. Catharines Site, which opened on March 24, 2013, replaces the two older St. Catharines sites, the St. Catharines General and Ontario Street sites, and brings new regional services to Niagara for the first time.
