Oakville, Ontario
Accountant in Oakville for incorporated businesses
Last reviewed: August 2026
Oakville businesses tend to be owner-run and incorporated, often with the owner doing the work as well as running the company. Trades, clinics, professional corporations, consultants and family-owned operations.
The question that comes up most in Oakville
Whether the corporation is still set up the way it should be. A lot of owners here incorporated years ago and never revisited it, so the share classes, the shareholder loan and the way money comes out have all drifted from what the business actually looks like now. That is worth an hour once, rather than never.
What we handle
Corporate tax, the owner's personal return and the family's, GST/HST, payroll and slips, and the bookkeeping underneath all of it. One firm and one fixed monthly fee, so the corporate and personal sides agree with each other.

What we handleQuestions
Do we need to meet in person?
Rarely. Document exchange and video calls handle almost everything, and our Mississauga office is a short drive down the QEW if something is worth sitting down for.
Do you work with professional corporations?
Yes. Professional corporations, practitioner-led clinics and consulting corporations are common Oakville files.
Can you take over from our current accountant mid-year?
Yes, and it is easier than most people expect. We request the prior year working papers and CRA authorisation, so you do not have to have an awkward conversation before it is arranged.
