EHS Manager

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 standards, and oversight protocols.
• Lead EHS input into bid submissions, proposals, and project execution plans.
• Engage with regulatory bodies (CNSC, OSHA, provincial regulators, and international equivalents) during the licensing and permitting process.

3. Regulatory Compliance, Governance, and Safety Culture

• Ensure all EHS program elements comply with applicable nuclear and
