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 conventional safety standards, including CSA N286, NQA-1, CNSC REGDOC requirements, and OSHA regulations.
• Conduct jurisdictional regulatory analysis to identify applicable health, safety, and environmental legislation in target markets and ensure project-specific requirements are developed accordingly.
• Research, interpret, and operationalize local regulatory requirements across multiple jurisdictions, including emerging nuclear markets (e. g., UK ONR, EU Directive 89/391, U.

S. state-plan OSHA programs, provincial COR requirements).

• Ensure Human Performance (HOP) standards and error-reduction tools are embedded into compliance structures, work planning, and supervisory expectations.
• Establish EHS governance structures for contractors, suppliers, and subcontractors that align with both Aecon standards and local regulatory requirements.
• Integrate Aecon’s CRM / Fatal 8, APEX, and Redbook EHSMS programs into project compliance frameworks.
• Champion nuclear safety culture traits across all development activities (aligned to INPO, WANO, IAEA and nuclear industry expectations) and support nuclear safety culture assessments and continuous improvement initiatives.
• 4. Risk Identification & Mitigation
• Lead early-phase EHS risk identification and assessment for new nuclear projects, including safety, environmental, and occupational health hazards.
• Develop risk registers and mitigation strategies tailored to new-build nuclear construction environments.
• Identify and address jurisdiction-specific EHS risks associated with entering new markets where Aecon has no established presence.
• Provide EHS input to project risk management processes, including HAZID, HAZOP, and constructability reviews.
• Assess environmental risks (contamination, spill potential, ecological impact) and occupational health risks (exposure pathways, noise, dust, radiation) during the pre-execution phase.
• 5. Execution Readiness & Continuous Improvement
• Ensure EHS systems, programs, and procedures are fully developed, documented, and ready for deployment prior to construction mobilization.
• Ensure readiness of the EHS organization structure and resource plans prior to construction mobilization.
• Maintain and continuously improve the New Build EHS Standup Playbook based on lessons learned, regulatory changes, and project feedback.
• Develop EHS training, orientation, and competency frameworks for new-build projects, scalable across jurisdictions.
• Leverage digital tools and data analytics (eg.

Power BI, Site Docs, Cority, and emerging AI-enabled monitoring) to design, track, and continuously improve EHS performance from project inception.

• Establish KPI frameworks, reporting structures, and leading/lagging indicator dashboards for new-build EHS programs.
• Prepare EHS components for project readiness reviews, gate assessments, and regulatory audits.
• Ensure environmental management plans and occupational health programs are execution-ready.
• 6. Leadership & Advisory
• Act as a trusted EHS advisor to NND leadership, providing strategic counsel on safety, environmental, and regulatory matters.
• Champion nuclear safety culture and Human Performance principles across the NND team.
• Interpret and communicate international regulatory requirements to project teams operating in unfamiliar jurisdictions.
• Support the growth of the NND EHS function; this role is expected to evolve as the portfolio scales.
• Contribute to industry forums, working groups, and benchmarking activities related to new nuclear EHS best practices.
