Feshchenko Professional Corporation is a professional Chartered Accountancy firm located in Ottawa, ON, regulated by CPA Ontario. Our Ottawa Accountants provide accounting and tax services to both individual and corporate clients. Our clients trust us every day to provide timely, technically correct, competent and reliable service so they can comfortably focus on their ventures. We are a modern firm, and use cutting edge software tools and processes for maximum efficiency, which translates into higher quality work and more affordable pricing. 

As with most things in life, you get what you pay for. Good quality accountants deserve their reputations just as they deserve to be paid for their work. Very often, a less expensive accountant will actually be much more expensive in the long run than the most expensive accountant due to errors they make that costs the client money in the form of overpaid taxes, missed opportunities to save on taxes, imposed penalties, wasted time, paying someone else for rework and dealing with the issues. In many cases, these costs go unnoticed for years, especially overpaid taxes and missed opportunities. We strategically focus on these areas, and your experience with us will be outstanding, guaranteed.

Feshchenko Professional Corporation has earned excellent reputation that all our clients can attest to and our testimonials are a reflection of their trust in us. We look forward to working with you and building a long-term relationship for many years to come. We invite you to contact us to schedule a no cost no obligation meeting.

"Choosing a good accountant to serve both our personal and business needs can be a daunting task. That is why I highly recommend the accounting firm of Mr. Sviatoslav Feshchenko, CPA, CA. As we must entrust them with very personal and important information, trustworthiness and competency are an absolute must. Mr. Feshchenko exceeds these qualities, while providing our dental office with practical advice, timely reporting and an explanation of our operations in a language that we understand. Over the last 20 years, our business has partnered with numerous accountants. We have finally found the “The Great One” as Mr. Feshchenko makes accounting simple but most importantly, his attention to detail deserves the greatest merit. No accounting issue is overlooked. That says a great deal about his standards of practice. I recommend Mr. Feschenko to family and friends as he has shown time and again his mastery in the field of numbers and his ability to relate to his clients in a personable manner."

"We transitioned from being a sole proprietorship enterprise into a corporate one at the beginning of 2014, at the time, we were looking for a new accountant that would help us with this transition. We did our research, even had a couple of referrals from family and other businesses in the same industry but as soon as we met with Mr. Feshchenko, we did not look any further. Slava, as he prefers being called, helped us tremendously with such a daunting, complex and overwhelming transition. All our questions were answered, and he did it by explaining in ways my wife and I can understand. He helped my wife (who has the most basic of financial backgrounds) with the books, gave advice and suggestions for her work to run more efficiently. I do not doubt that our books are clean and compliant because of Slava’s expertise, he does both our personal and corporate returns, sits down with us every time to discuss anything that has changed that could potentially affect our tax situation. He is a phone call away and always encourages us to send him an email or call whenever we need help. We have nothing but great things to say about Mr. Feshchenko, we can recommend him again and again!"

We called around to several accountants one of whom was Sviatoslav and with a warm, friendly and professional manner I was interested in setting up a meeting with Sviatoslav. When meeting for the first time, he made us feel very at ease and answered all of our many questions. The stand out for us and for our business is the ease of communication with our accountant. The prompt and accurate service that we have experienced through phone, email or in person makes business with our accountant a pleasure and is certainly the making of a long business adventure. We would definitely recommend Feshchenko Professional Corporation Chartered Professional Accountants to anyone looking for superior Accounting Services that doesn’t just look after your accounts, they look after you as a person and as a business and we are looking forward to working together in the coming years."
