Pinawa is a small Canadian community located in southeastern Manitoba, east of Winnipeg.
The town is situated on the Canadian Shield within the western boundary of Whiteshell Provincial Park, which lies near the Manitoba-Ontario provincial boundary.
The community was established to support the operation of Manitoba's first hydro electric generating station but was abandoned in 1951 when the site was shut down.
Pinawa was re-established in 1963 after Atomic Energy of Canada Limited built the Whiteshell Laboratories, a nuclear research facility, taking into account the area's seismic stability. Pinawa was developed as a planned community; Whiteshell Laboratories was somewhat similar to the Chalk River Nuclear Laboratories in Deep River, Ontario.
AECL closed the Whiteshell Laboratories in 1998 and the facilities are currently being decommissioned while the economy of Pinawa is diversifing.
