Aecon, AtkinsRealis picked again to manage Ontario’s $19B Pickering nuclear overhaul

Aecon and AtkinsRealis have been selected to help manage the overhaul of the Pickering Nuclear Generating Station, a project valued at about $19 billion.

The work is intended to refurbish the plant and extend its operating life by 38 years, according to officials cited by Engineering News-Record.

The project is in Pickering, Ontario, and the selection was reported on Sept. 28, 2026.

Officials said the refurbishment is also aimed at strengthening Canada’s domestic energy sector amid U.S. tariffs and other actions by the Trump administration, though they said risks remain ahead.

Engineering News-Record reported the selection and project details.

Why it matters for AEC

Large nuclear refurbishments require coordinated delivery across complex technical scopes, long schedules and regulated interfaces. For AEC firms, the stated 38-year life extension and commercial backdrop signal a high-stakes program where execution risk and long-duration project controls will be central.

What this signal may mean for staffing or delivery capacity

A project of this scale and technical complexity may create sustained pressure on delivery capacity, specialized engineering coordination and field management. The repeated selection of the same firms suggests their ability to handle large nuclear work warrants monitoring as the overhaul moves forward.
