Whether dealing directly with the CRA or providing highly professional commentary on all facets of business, from agreements to contracts to tax implications, he’s always got the right answers, and his creativity and ability to go to the limits always astounds me. Frankly, in all my 48 years of providing a high level of financial advice, I have found no other as good and effective as Derek. He is simply beyond the level of any accountant I’ve worked with over the years. I’m privileged and proud to be associated with him, and one could not do better than have him working with them.

  • As a busy public accountant, I have relied on Derek Dalsin as a resource when it comes to complex tax and accounting matters that I simply cannot spend the time on. Derek has been extremely knowledgeable and is able to use ‘tax speak’ when dealing with CRA and also in the court system. He has been able to assist by providing me with the relevant tax and accounting references to allow me to service my clients as well as appear in tax court for my clients, which is a service that I cannot provide. Due to his many years of experience, he is able to postulate different outcomes for any situation so that preparatory planning can occur. I recommend and appreciate his assistance to me with my practice clients.
