If you’re looking for a full-service accounting firm who can help build a strong financial foundation for your small business, we’d love to hear from you.



Matt Cassar founded Stonehenge Accounting with his father Lewis in 2011. The Cassars come from a long line of entrepreneurs and created Stonehenge to be the type of accounting firm that their entrepreneurial family members wish they could have had.

Prior to fully embracing his entrepreneurial spirit, Matt spent years honing his craft as an accountant working for various Bay Street firms. However, he found that he most thrived outside of the corporate structure, where he was helping clients directly achieve their goals. For this reason, Matt chose to take over Stonehenge full-time, and has never looked back since.

Today, Stonehenge has grown beyond just a typical accounting firm, and works closely with clients on all aspects of their business. We are proud to be part of a tight-knit community of business leaders in Toronto.

You simply won't get this quality of service from a big firm.
Stonehenge has saved me a lot of time, money, and headache!
Their diligent approach and personal care have saved me thousands of dollars in taxes over the years!
Stonehenge will take the time to develop a meaningful relationship with you and an understanding of your needs and goals.
We love Matt and his team! We use them for our NFP organization and they're always fast, flexible, and knowledgeable.
I've been working with Matt for a while now and I recommend him as much as I can to my friends and family.
