Core Accounting Inc. was built to give small business owners and incorporated professionals access to the kind of accounting advice that usually only larger firms receive.
Most small business owners interact with their accountant once a year — hand over a box of receipts, get a number back, and wonder if they're actually paying too much. That's not accounting. That's data entry with a signature.
Core Accounting was built around a different model. Every client gets proactive communication, strategic advice alongside their filings, and an accountant who responds within 48 hours. Not just at tax time — year-round.
We're based in Pickering and serve clients across Durham Region, the GTA, and across Canada — fully remote for clients outside the area, in-person where preferred.
We don't wait for you to ask. If something in your file creates a planning opportunity or a risk, we bring it to you — before it becomes a problem or a missed window.
48-hour response time, year-round. Tax questions don't only come up in April. We're reachable when it matters — not just at filing time.
Every engagement is quoted upfront. You know what you're paying before we start. No hourly billing, no scope creep, no invoice surprises.
We work on complex files — RDTOH, CDA, cross-border, multi-entity, HST audits. If your situation has moving parts, we've handled it before.
We file with the assumption that CRA could review any return. Positions are documented, elections are filed, and nothing is left to chance.
Secure document portal, video calls, and e-signatures mean we work with clients from Pickering to Vancouver. No office visit required — ever.
Got my personal and corporate taxes filed for 2025, and it was a smooth process from start to finish. Very professional. Highly recommend.
They've been handling our small business bookkeeping and payroll for the past 8 months and it's been a huge relief. Very organized and professional, and they always answer questions quickly.
What I liked most was how organized everything was. My 2025 personal and corporate filings were done cleanly and on time.
Core Accounting has prepared and filed thousands of personal and corporate returns for Canadian business owners, incorporated professionals and investors — from straightforward T1s to complex files involving RDTOH, the capital dividend account, HST audits and cross-border matters.
