JOB OVERVIEW

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

Reporting to the SVP Nuclear Sustainability Strategies, this position is responsible to provide comprehensive executive support—including travel coordination, expense management, calendar oversight, meeting documentation, and stakeholder relations—to senior Hydro business development leaders, leveraging advanced administrative skills and professionalism.

KEY ACCOUNTABILITIES

Prepare, submit, and track detailed expense reports primarily through Concur, ensuring accuracy, timely processing, and strict adherence to company policies.
Proactively manage multiple executives’ calendars, including scheduling meetings across time zones, resolving conflicts, and collaborating with other administrative staff to ensure alignment and availability.
Organize, attend, and document key meetings by preparing agendas, taking accurate minutes, tracking action items, and distributing follow-ups as required.
Draft, proofread, and format correspondence, reports, and presentations using Microsoft Word, Excel, and PowerPoint; ensure all documents meet corporate standards.
Build and maintain strong working relationships with internal and external stakeholders, acting as a professional representative for the executive team and facilitating smooth communication.
Maintain efficient office systems, suggest improvements to administrative processes, and support the smooth operation of the business development group.
Handle sensitive information with discretion and maintain a high level of professionalism in all interactions, leveraging 7–10 years of executive support experience to anticipate needs and resolve issues proactively.

QUALIFICATIONS

Post secondary diploma/degree in Business Administration, Communications, or a related field preferred.
Over 7 years experience working with managing calendars, processing expense reports coordinate and book complex travel arrangements (flights, hotels, transportation) for senior managers and directors.
Proven expertise in coordinating complex travel arrangements and managing expense reports, with strong proficiency in Concur or similar systems.
Advanced skills in calendar management, meeting scheduling, and collaboration tools such as Microsoft Outlook, Teams, and Office Suite (Word, Excel, PowerPoint).
Exceptional written and verbal communication skills, with experience drafting, proofreading, and formatting professional documents and correspondence.
Strong relationship-building and interpersonal skills, demonstrating professionalism and discretion when interacting with stakeholders at all levels.
Highly organized with a proactive approach to office management, process improvement, and the ability to maintain confidentiality in handling sensitive information.

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 and the United States, 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.
