Source-derived summary

Lakeridge Health is a health system and hospital network serving Durham Region, Ontario in the eastern part of the Greater Toronto Area. It operates four acute hospitals with emergency departments (Bowmanville, Oshawa, Port Perry, Ajax and Pickering), one specialty hospital with a regional mandate (Whitby) and a variety of offsite locations. Lakeridge Health is part of the Central East Local Health Integration Network (CE LHIN) and a community-affiliated hospital of the University of Toronto.

History

After a recommendation from the Health Services Restructuring Commission in 1998, the Ontario government amalgamated four Durham area hospitals: Memorial Hospital Bowmanville, North Durham Health Services (consisting of Community Memorial Hospital Port Perry and Uxbridge Cottage Hospital), Oshawa General Hospital and Whitby General Hospital – to create what is now known as Lakeridge Health. In January 2004, the Uxbridge site became aligned with Markham Stouffville Hospital and left the Lakeridge grouping.

With the merger of Rouge Valley Health System and The Scarborough Hospital, management of the Rouge Valley Ajax and Pickering site was transferred to Lakeridge Health on December 1, 2016.

The President and Chief Executive Officer is Cynthia Davis.

On May 13, 2017, Lakeridge Health was attacked by the WannaCry ransomware attack among many other institutions around the globe. By afternoon, most areas were up and running again.

On April 26, 2018, Lakeridge Health launched an online platform MyChart for patients to manage their health information.

Editorial analysis

Why this record matters

The subject matters to the general reference register because the source frames it as hospital in Ontario, Canada. Its deeper value depends on whether names, dates, institutions and citations support that framing.

Evidence profile

Vocabulary and entity names are the principal evidence signals here, because they determine the precision of every later search. The source revision retrieved here is dated Sep 20, 2026. The linked authority identifier is Q6478921. Authority coordinates are 43.906, -78.869. 1 of 2 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank. The first chronological checks are 1998, 2004, 2016 and 2017.

Critical limits

A concise general-reference account can conceal disagreements about scope, terminology or the weight assigned to individual sources. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
