Areas We Serve in Ontario
From the Greater Toronto Area to Northern Ontario — and every town and village in between — we serve the whole province.
BOMCAS Canada is proud to serve individuals and businesses across the entire province of Ontario. From the largest cities to the smallest towns and villages, we deliver professional tax, accounting, bookkeeping and advisory services with the same care and rigour everywhere. Through a combination of personal service and secure cloud technology, your location is never a barrier to receiving expert support.
The Greater Toronto Area
We serve clients throughout the Greater Toronto Area, including Toronto, Mississauga, Brampton, Markham, Vaughan, Richmond Hill, Oakville, Burlington and the wider Peel, York, Durham and Halton regions. The GTA's diverse economy — from finance and technology to real estate, retail and professional services — means businesses and individuals here have sophisticated needs, and we are well equipped to meet them.
Ottawa and Eastern Ontario
In the nation's capital and across Eastern Ontario, we support professionals, public servants, business owners and families in Ottawa, Kingston, Cornwall, Brockville and the many communities in between. Whether you are an Ottawa consultant, an Eastern Ontario small business or a family managing investments, our team provides accurate, proactive support.
Hamilton, Niagara and the southwest
We serve Hamilton, the St. Catharines and Niagara region, London, Windsor, Kitchener-Waterloo, Cambridge, Guelph and the agricultural and manufacturing communities of southwestern Ontario. From family farms to manufacturers to the region's growing technology sector, we understand the businesses that drive this part of the province.
Central Ontario and cottage country
From Barrie and Simcoe County to the Muskoka and Kawartha lakes, we serve the businesses, seasonal operators and families of central Ontario and cottage country, including Orillia, Peterborough and surrounding communities. We understand the unique considerations of tourism, hospitality, seasonal businesses and property in these areas.
Northern Ontario
Distance is no obstacle to quality service. We support clients across Northern Ontario, including Greater Sudbury, Thunder Bay, Sault Ste. Marie, North Bay, Timmins and the resource, service and small-business communities of the region, all through secure online collaboration and responsive support.
Towns, villages and rural communities
We are especially proud to serve the many towns, villages and rural communities that are often underserved by larger firms. Wherever you are in Ontario, you have access to the same expert, proactive accounting and tax support as clients in major centres. Our secure cloud platforms and video consultations bring our full service directly to you.
How we serve clients everywhere in Ontario
Our province-wide reach is made possible by a thoughtful blend of technology and personal service. You can send documents securely online, meet with us by video, and have your books maintained in real time on leading cloud platforms — or meet in person when that suits you better. Either way, you receive accurate work, proactive advice and prompt, friendly communication.

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.
