Mississauga, Ontario
Accountant in Mississauga for incorporated businesses
Last reviewed: August 2026
Our office is in Mississauga and it is where the largest share of our clients are. Incorporated owner-managed businesses across most industries, from the first employee to the fifteenth.
Who we work with here
Trades and service businesses out of the industrial corridors, clinics and practitioner-led practices, retail and e-commerce, professional corporations, consultants, and holding companies sitting above one of those. If you are incorporated in Ontario and the person who owns the business also runs it, you are the kind of file we do.
You can actually come in
Most of the work happens over email and video calls because that is faster for both sides. But you can drop documents off rather than scanning them, and we can sit down in person when something is worth sitting down for.
What we do for Mississauga businesses
- Corporate tax (T2), including the year-end close and CRA correspondence
- Personal tax (T1) for the owner and family, prepared alongside the corporate return
- GST/HST registration, filing and input tax credit review

What we handleQuestions
Do you have an office in Mississauga?
Yes. Suite 400, Plaza 3400, 2000 Argentia Rd, Mississauga ON L5N 1V9. Most work is done remotely, but you are welcome to come in.
Do I need to be in Mississauga to work with you?
No. Clients are across Mississauga, Oakville, Vaughan, Markham and Toronto, and the work is the same wherever you are in Ontario. Corporate and GST/HST rules are federal and provincial, not municipal.
Do you only work with certain industries?
No. We know contractors and trades, health and wellness clinics and med spas best, but most of what an owner-managed corporation needs is the same whatever it sells. If your industry has rules we do not know, we will say so on the first call.
