Clients engage us in many ways throughout the year, according to their unique situation and needs. Services range from assisting with compliance (preparation and filing) of HST to complex planning for business start up, expansion and succession. Our clients benefit from their firm being part of The AC Group regional network, as specialized expertise at one firm can be a resource to any of the member firms.


In addition to filing required corporate tax returns for our clients, we are constantly looking for ways to keep their tax bills to the legal minimum. We provide a broad range of planning services that commonly involve estate plans, corporate reorganizations and income splitting techniques.


We provide tax advice and tax return preparation services to a wide variety of individuals. We are often called upon to assist clients in their cross-border tax reporting.


GST/HST rules are complex and often difficult to understand. Failure to comply with the rules can result in considerable tax liability, as well as an exposure to potential interest and penalties. All firms are able to advise clients on GST/HST rules, and several have highly qualified individuals who specialize in GST/HST services.

Estate and Trust Returns

We are often called upon to assist in the preparation of the final tax return and trust returns for the estates of deceased taxpayers. This is a complex area of tax law and the advice of a lawyer and tax accountant are a must.

"I was in the banking business for 20 years and worked with accounting firms of all types and sizes. When I made a career change 10 years ago one decision that was very easy to make was to use a local CA firm. I had seen first hand the importance of receiving personal, uninterrupted accounting and financial advice."

"We appreciate the level of service and attention a local firm provides, and the knowledge that as we grow, they have the backing of the AC Group association to grow with us."

“Independent Insurance Brokers understand the value of supporting the community where we make our living. So our Company made a decision to contract out services to "local" rather than "out of town" suppliers, provided that the quality, dependability and value aspects were at acceptable levels.  McIsaac Darragh Chartered Accountants were one of the first firms contacted in this regard and since 1989 have provided tax and accounting services that matched and bettered the above criteria. As a company we are very happy to be in partnership with a local firm who can be contacted quickly if the need should arise and will respond rapidly and in a totally professional manner to give correct advice at the right time. McIsaac - Darragh have grown with us and share in our success.”
