JOB OVERVIEW

Ontario Power Generation (OPG) is looking for a dynamic, strategic and results-driven professional to join our team in the role of Assistant Project Leader,

Reporting to the Senior Project Manager, the Assistant Project Leader is responsible for the planning and execution of major projects associated with a $1B, 15-year capital program to replace and upgrade major equipment and assets. In this role, you’ll have the opportunity to assist in leading the rehabilitation of the Sir Adam Beck generating station, which is one of the largest and most iconic hydroelectric generating stations in North America.

KEY ACCOUNTABILITIES

Assist senior staff with coordinating and controlling defined stages of project management, ensuring alignment with Project Management governance throughout various phases of the project.
Support the implementation of approved Project Management processes, including phase-gating, scope management, schedule and cost control, change management, risk management, and reporting.
Help manage the engineering, procurement, and construction aspects of assigned projects, ensuring all objectives are met within safety, quality, budget, and schedule targets.
Assist in preparing Business Case Submissions for senior management, the Executive Office, and the Board of Directors, ensuring proper documentation is prepared for project approval and fund release.
Maintain close liaison with field construction teams and operations, addressing design, schedule, and costing issues, while assisting in regular reporting of project status and managing changes as required.
Assist in resolving issues and ensuring that any changes to scope, schedule, and cost are managed in accordance with established procedures, aiming to keep the project on track and within plan.
Facilitate communication with internal and external stakeholders, regulatory bodies, and other relevant parties, coordinating meetings and directing discussions to achieve project goals efficiently.
Stay informed on technological advancements in project management, engineering, and construction, ensuring compliance with corporate and local procedures and advising when compliance challenges arise.

QUALIFICATIONS

4-year university degree, in Engineering, Science, Business, Economics or other related field.
2+ years of experience in project management, specifically, in developing project requirements and plans; preparing cost estimates; participating in contract bidding and award processes, managing projects and contracts in execution phase, and managing project closeout.
Heavy industrial construction experience in the power generation industry is a strong asset.
Sound knowledge and familiarity with equipment and processes in hydroelectric generating stations.
Prior experience in managing conflicting priorities of scope, schedule, cost and quality.
Excellent problem-solving abilities and the ability provide guidance.
Experience and knowledge of cost accounting and forecasting as it relates to project management.
Experience in managing projects of increasing complexity is considered a necessary requirement; project complexity would normally be defined by multiple-contract, multiple stakeholder projects with schedule constraints.
Ability to work effectively and efficiently in a flexible hybrid office environment.
Excellent interpersonal and communication skills and highly developed organizational skills

The successful candidate will exhibit uncompromising integrity and commitment to upholding corporate values, and the OPG Code of Business Conduct.

OPG is committed to fostering an inclusive, equitable, and accessible environment. If you require accommodation during the selection process, please contact [email protected]

What makes a career at OPG different?

With operations across Ontario, OPG is one of the most diverse power producers in North America. As the largest generator in Ontario, we meet approximately 50% of the province’s electricity needs, largely from low-carbon sources like nuclear and hydro.

As we work to achieve our vision of Electrifying life in one generation, OPG and our family of companies are also helping advance the development of new low-carbon technologies such as Small Modular Reactors (SMRs), refurbishment projects, and electrification initiatives to help power the growing demands of a growing economy. Join OPG and make history.

Please submit your application online at https://jobs.opg.com/. OPG thanks all those who apply; however, only candidates considered for an interview will be contacted.

Please note: All job postings at OPG are to fill existing vacancies within our organization.

OPG may use artificial intelligence (AI) tools as part of the applicant screening process. However, applications will also be reviewed by a member of our Recruitment team to ensure a fair and thorough assessment.

The base salary range considers many factors including, but not limited to experience, education, and training, including any collective agreement requirements for union represented positions. It is not typical for the salary to be offered near the top of the range, and salary is dependent on numerous factors. For management roles, the base salary range does not represent the total compensation package. The total compensation package for regular full-time management roles includes pay-for-performance programs for annual and medium time periods. Maintaining a high-performance culture and excellence is a core expectation of every member of our leadership team and is rewarded through the established compensation framework.

OPG is committed to employment equity. As such, we encourage applicants from equity-seeking communities (Indigenous Peoples, racialized persons, persons with disabilities, and women). We strongly believe that alleviating the under-representation of equity-seeking individuals will create a stronger OPG team and allow us to better serve the needs of our diverse communities.

In order to fulfill the above-mentioned purpose, priority in hiring may be given to qualified persons who self-identify as a member of equity-seeking groups as identified in the application process. This initiative constitutes a special program under the Human Rights Code/Canadian Human Rights Act.
