Community Overview

Northumberland County is located in southeastern Ontario along the north shore of Lake Ontario, approximately 100 kilometres east of Toronto.

The County is composed of several lower-tier municipalities, including the Municipality of Port Hope and the Town of Cobourg. With a population of approximately 90,000 residents, Northumberland County plays a key role in regional planning, infrastructure, and service delivery.

Nuclear Presence

Northumberland County is home to significant nuclear-related activities, primarily located within the Municipality of Port Hope.

Key facilities and projects include:

  • Cameco Port Hope Conversion Facility, operated by Cameco Corporation
  • Port Hope Area Initiative (PHAI), led by Canadian Nuclear Laboratories, focused on the remediation and long-term management of historic low-level radioactive waste
  • Proposed Wesleyville nuclear generating station project, currently in early-stage regulatory consideration

These activities reflect Northumberland County’s role in supporting nuclear fuel cycle operations, environmental remediation, and potential future energy development.

Role in Supporting the Nuclear Sector

As a regional government, Northumberland County:

  • Engages with member municipalities, industry, and government on matters related to nuclear development and regional growth
  • Supports regional infrastructure, planning, and services associated with nuclear-related activities
  • Participates in discussions related to environmental stewardship and long-term project impacts
  • Contributes to coordinated approaches across municipalities on shared priorities

Northumberland County’s participation in CANHC includes representation from local municipal leadership across the region, including Mayor Lucas Cleveland of the Town of Cobourg.

Northumberland County’s experience highlights the important role that regional governments play in supporting informed, coordinated approaches to nuclear-related activities.
