Lakeridge Health Ajax and Pickering (formerly Rouge Valley Ajax and Pickering) is a hospital in Ajax, Ontario that operates as part of the Lakeridge Health network.
It was founded in 1954 as the Ajax and Pickering General Hospital with 38 patient beds. New four-storey wings were added in 1964 and 1994. A major $80 million redevelopment project was completed in 2010. Almost 25 percent of the hospital was renovated.
The hospital has a capacity of 144 beds, and is raising $5 million to procure a new magnetic resonance imaging (MRI) machine to support the large population growth in the area. The Emergency Department was originally designed to accommodate 20,000 visits a year, but now routinely handles 45,000. It is equipped with a helipad for medical evacuations.
