Core Accounting Inc. Core Accounting
Rooted in Durham Region

Your Durham Region accountant, built for local business.

Core Accounting works with small businesses, incorporated professionals and families across Pickering, Ajax, Whitby, Oshawa and Clarington. Full-cycle accounting and tax on fixed fees, handled virtually so you get more access for less overhead.

A local firm that works the way you do

Durham runs on owner-managed businesses: trades and construction, professional services, real estate and rentals, e-commerce, and the self-employed. Those businesses need more than a return once a year. They need clean books, payroll that runs on time, HST handled correctly, and a year-end T2 that reflects real planning rather than a scramble in June.

We are a Durham firm by design, and virtual by choice. Keeping the practice lean means lower fees for you and an accountant who answers questions throughout the year, not just at deadline.
