EHS Manager Job Cambridge area,Ontario Canada,Management

What is the Opportunity?

Aecon Nuclear is growing its New Nuclear Development (NND) portfolio across Canada, the United States, and emerging international markets. As the organization pursues First-of-a-Kind (FOAK) and follow-on new-build projects, there is a critical need for a dedicated EHS leader who can shape safety, environmental, and occupational health strategy from the earliest stages of project development — well before ground is broken.
The EHS Manager – New Nuclear Development will be embedded within the NND team during the development, bid, and pre-execution phases. As a key member of the NND team, the EHS Manager works closely with clients, engineering, quality, and project leadership. This role is responsible for building a scalable, compliant, and execution-ready EHS framework — including reusable playbooks, templates, and tools — that can be deployed efficiently across jurisdictions with varying regulatory landscapes.

The successful candidate will bring deep knowledge of nuclear safety culture, multi-jurisdictional regulatory environments, and the ability to stand up an EHS program on a greenfield project from scratch.

New nuclear development is defined by complexity, regulatory scrutiny, and long project lifecycles. EHS decisions made during the definition and pre-execution phases have outsized impact on execution safety, regulatory standing, schedule, and cost. This role ensures that EHS is not an afterthought but a foundational pillar of every new-build project from the earliest point possible — across every jurisdiction Aecon enters.

What You'll Do Here:

1. EHS Strategy & Program Development (New Build Focus)

Lead the development of project-specific EHS strategies for new nuclear projects during the definition, bid, and pre-execution phases.

Build and maintain a New Build EHS Program Standup Playbook – a modular, repeatable toolkit of templates, procedures, plans, checklists, and training matrices that enables efficient mobilization of EHS programs on new nuclear projects across jurisdictions.

Conduct jurisdictional regulatory research to identify and map applicable health, safety, and environmental legislation in each target market (provincial, state, national, and international).

Embed Human Performance (HOP) principles and error-reduction tools into project safety strategy, work planning, and supervisory expectations from the earliest phases.

Integrate Aecon’s Critical Risk Management (CRM / Fatal
8) program, APEX framework, and Redbook EHSMS into new project safety strategies.

Ensure environmental management (spill prevention, emissions, species-at-risk, soil management) and occupational health (exposure monitoring, industrial hygiene) requirements are identified and planned for during the pre-execution phase.

Develop scalable, compliant, and execution-ready EHS frameworks that align with FOAK delivery models and support repeatable deployment on follow-on builds.

Incorporate operating experience (OPEX) and lessons learned from DNNP, refurbishment, and industry peers into all EHS program development.

2. Cross-Functional Integration & Stakeholder Engagement

Serve as the EHS subject matter expert within the NND project development team, integrating with Engineering, Quality, Procurement, Licensing, and Construction.

Participate in design reviews and constructability assessments to embed safety-by-design and environmental-by-design principles, including Human Performance considerations.

Collaborate with project partners, JV partners, alliance members, and client EHS teams under various delivery models (IPD, alliance, EPC, EPCM).

Develop and own subcontractor EHS management frameworks for new markets, including prequalification criteria, safety training requirements, competency…
