Why BOMCAS Canada
What our clients across Ontario say
When you engage BOMCAS Canada for accounting and tax services in Ontario, you work with a professional firm that takes responsibility for getting the details right. Below is what that commitment looks like in practice, and how a typical engagement works from your first call to ongoing year-round support.
Ontario and federal tax expertise
We work with the full Ontario tax picture every day — the 13% Harmonized Sales Tax (HST), Ontario personal tax brackets, provincial credits, and the federal rules that sit on top of them — so nothing is missed and nothing is misapplied.
Clear, fixed-fee quotes
You receive a clear scope and a fixed-fee quote before any work begins. There are no surprise invoices and no vague hourly meters — you always know what you are paying and what it covers.
Year-round support, not just tax season
We are available throughout the year for questions, planning and CRA correspondence, so decisions can be made with proper advice rather than guesswork between filing deadlines.
Direct CRA representation
With your authorisation we deal directly with the Canada Revenue Agency on your behalf — responding to reviews, adjustments and audit queries — and keep you informed at each step so you are never left guessing.
Secure, modern and remote-friendly
Documents are exchanged through secure digital channels, and the entire engagement can be handled remotely. Whether you are in a city centre or a rural community, you receive the same standard of service.
How we work with you
- 1. Free initial consultation We start with a no-obligation conversation about your situation, your goals and any deadlines or correspondence you are facing.
- 2. Clear scope and fixed quote We confirm exactly what is needed, what it will cost, and the information we require from you to get started.
- 3. Careful preparation and review Your work is prepared, cross-checked against current Ontario and federal rules, and reviewed by a second set of eyes before anything is filed.
- 4. Filing, explanation and ongoing support We file on time, explain the outcome in plain language, and remain available for follow-up questions and planning throughout the year.
