About Ontario Tax Team
We started Ontario Tax Team with a simple mission: make professional bookkeeping, tax, and accounting services accessible, affordable, and stress-free for every small business owner and individual in Southern Ontario.
Our Story
Ontario Tax Team was founded in Oakville with one goal: give small business owners and individuals the same quality financial services that large corporations enjoy, without the corporate price tag.
Over the past 30+ years, we've grown from a one-person practice to a team of dedicated bookkeepers, tax preparers, and qualified accountants serving 100+ clients across Oakville, Mississauga, Burlington, Milton, and the wider GTA.
We believe that every business owner deserves to understand their numbers. That's why we don't just crunch data. We explain it, strategize around it, and help you make smarter financial decisions.
Whether you're a contractor who needs clean books, a family filing their T1 return, or a growing company that needs corporate tax planning, Ontario Tax Team is here for you. Year-round.
