Tonin & Co. LLP Chartered Professional Accountants is based in Guelph, Ontario. The majority of our client base is located in Ontario, but also stretches across Canada and into the United States and Europe and covers both the public and private sectors. We emphasize an ongoing commitment to superior client relations, continuous staff development and team work. Our philosophy starts with our people. We care about our people and their families. We care about our clients, we do the best job for them that we can, and we strive to have fun as well! We often hear from our clients that they feel that we are part of the team helping to drive the organization forward, rather than just being the accountant/auditor – this is what sets us apart from other firms.
