NOTICE OF ROAD CLOSURE – Catherine Street: Phase 1

As part of Port Hope Area Initiative activities, CNL contractors will be performing field work on Catherine Street. To minimize the impact on the surrounding community it will be divided into four phases.

Phase 1 will include a road closure on Catherine Street between Percy and Elizabeth Streets beginning at the end of July and continuing through September 2025.

Flaggers will assist with traffic control. Please be careful when travelling in the area and obey all posted signage.


Canadian Nuclear Laboratories is committed to the safety of the public, its workers and the environment while undertaking this community-requested solution to a longstanding environmental issue.
