Ontario Accountant
Ontario accountant for private companies
Amir Rosenthal, CPA, CA, LPA, CBV, CFF, provides accounting and tax support to private companies across Ontario. The practice is based in Toronto.
Accounting and tax across Ontario
Most private companies need an Ontario accountant who can close the year, keep filings in order, and speak plainly about cash, tax, and the next transaction. The work here covers that: year-end, filings, and plain advice on cash, tax, and transactions.
Work typically includes year-end financial statements (compilation, review, or audit), corporate tax, owner compensation, and planning around a hire, a lease, a refinance, or a reorganization. When a file needs a formal valuation, the same practitioner can take it up as a business valuator. Forensic accounting and SR&ED and government incentives are available where those files arise.
One practice, province-wide
Clients in Toronto, North York, the GTA, and elsewhere in Ontario are served from the same Toronto office—in person, by video, or by phone. Location in the province does not change the scope of the work. This page is the province-wide framing; the Toronto and North York pages focus on the midtown office and North York clients respectively.
Who this is for
Incorporated, owner-managed companies and start-up teams that want a Chartered Professional Accountant in Ontario with a valuation and transaction background.
- Private companies across Ontario
- Founders who have outgrown bookkeeping-only support
- Shareholders thinking about buying or selling
For the midtown Toronto office itself, see Toronto accountant. North York clients are covered under North York accountant. Services and industries are listed separately.
Common questions
Is this an Ontario accountant with offices around the province?
The practice is based in Toronto at 110 Eglinton Ave W, Suite 201. Amir Rosenthal serves clients across Ontario from that single office. Meetings can be in person, by phone, or by video.
Do you work with businesses outside Toronto and the GTA?
Yes. The practice is Ontario-wide. Toronto, North York, and the Greater Toronto Area are a substantial part of the work, and clients elsewhere in the province are served from the same office.
What kind of Ontario accountant is this practice?
Amir Rosenthal is a Chartered Professional Accountant and Licensed Public Accountant in Ontario. The work covers accounting and tax, plus business valuation and forensic accounting when a transaction, dispute, or investigation requires it.
How do clients outside the GTA work with a Toronto-based practice?
Work can run by video, phone, and secure document exchange. In-person meetings at the Eglinton office are available when a file warrants the trip. Location in the province does not change the scope of accounting, tax, or valuation work.
Are SR&ED and government incentives available province-wide?
Yes. Potential SR&ED and incentive opportunities can be identified for technical private companies across Ontario, with SR&ED specialists preparing the claim and the accounting and tax side coordinated with year-end. See the SR&ED and government incentives page for how that work is divided.
