Port Colborne
Principal

James Brennan

I manage Grant Thornton’s Port Colborne office, where we offer world-class assurance services to companies and organizations in the Niagara, Hamilton and Burlington areas of Southern Ontario.

During my 30-year career, I’ve worked with a wide range of privately held businesses, public sector organizations, and municipal and not-for-profit entities.  Beyond my core focus on financial audits, I specialize in corporate and personal income tax reorganizations and planning and pension plan audits. It’s very rewarding to work with my clients on solutions that earn the approval of management, audit committees, stakeholders and investors.

Helping to build and strengthen our community is important to me. I’m the treasurer for Bridges Community Health Centre and an active member of the Port Colborne – Wainfleet Chamber of Commerce. I also love to travel, explore new destinations and immerse myself in diverse cultures.
