National Assurance Service Line Leader

John Harris

I work with our talented team to deliver high quality assurance service that provide businesses across Canada with the confidence they need to navigate complexity. By ensuring our professionals have the right tools, expertise, and support, I help uphold the high standards of reliability, trust, and insight in everything we do.  

The client-centric mindset at Doane Grant Thornton is what sets us apart. We’re committed to creating exceptional experiences for our clients, mirroring the hard work and dedication of the businesses we serve. I’m passionate about growing a team that embodies these values every day — one that not only delivers technical excellence but also values our strong relationship with our clients. By asking good questions, I help identify and connect businesses with the Doane Grant Thornton specialists best suited to meet their unique needs. 

Prior to stepping into my current role, I led the Lower Mainland and Fraser Valley team as the Managing Partner of South Coastal British Columbia.  For more than 30 years, I’ve advised privately-held clients across British Columbia—providing both assurance and business advisory services. While I’ve covered a broad range of topics over the years, my strength lies in taking a holistic view to help clients crystalize their objectives and align their strategies for long-term success.
