These Firms Were Hand Picked Based On Reviews, Reputation & Brand Authority Online. No Specific Order.

If you’re running a business or just trying to get your personal finances sorted, finding a good accountant can take a huge load off your plate. The thing is, not all firms are built the same. Some specialize in small businesses, others are better for cross-border taxes, and a few are tech-savvy with cloud-based solutions.

So, I put together this guide to help you compare five of the best accounting firms in Oakville — what they’re all about, what makes them unique, who’s on the team, and what services they offer.

Let’s get into it.

Frequently Asked Questions (FAQ)

How much do accounting firms charge in Oakville?

It really depends on the complexity of your needs. For basic personal tax returns, you might pay around $150–$300. Small business bookkeeping and tax services can range from $200/month up to $2,000+ for more involved corporate tax planning or audits.

If you’re self-employed, own a business, or have investments, an accountant can save you time, money, and potential CRA headaches. Even for individuals, they can often find deductions you might miss.

A CPA (Chartered Professional Accountant) has passed rigorous exams and has to meet ongoing education and ethical standards. All CPAs are accountants, but not all accountants are CPAs. If you need tax planning, audits, or more complex financial advice, look for a CPA.

Depends on your comfort level. Local firms give you that face-to-face connection and community familiarity. Virtual firms are great if you’re tech-savvy and want fast, on-demand service.

Ask about their experience with your type of business, how they communicate (email, phone, virtual meetings), and what software they use. Also ask how they charge — hourly, monthly packages, or by service.
