We have been serving the community for over 30 years. When you are buying or selling your home, you need careful attention to detail. When you are preparing your Will or Powers of Attorney, you want your instructions to be followed. When you’re facing legal challenges in the workplace or in your marriage, you need answers tailored to your specific needs. We can help whether you are legally married or common law. We can assist you with Marriage Contracts, Cohabitation Agreements and Separation Agreements. You want someone to listen to your concerns.

We care for our clients. That is easy to say.  What do we mean?  When we agree to take on your problem, we want you to know that a burden has been lifted from your shoulders.  The team at Mackenzie & Mackenzie will keep you informed and seek your input on all steps of your matter.  You will always know the status of your dispute and the next step to take.  We will call you.  We will write to you.  You will always know where you stand.

Our Philosophy


Our first focus in our firm philosophy is on integrity and trust. A solid lawyer-client relationship can’t exist in the absence of trust; therefore, we strive every day to foster trust that leads to a productive and mutually beneficial lawyer-client relationship. While we work daily to build trust with our clients, we also strive to maintain our good reputation and trust with opposing counsel and the tribunals before which we appear. We believe that by promoting professionalism and civility in all aspects of our legal representation, mutual respect and trust allow us to advocate effectively for our clients.


Our firm philosophy is also based on clear communication and prompt service. We provide sound solutions to our clients’ legal problems in an efficient manner. We have a dedicated team of professionals that understands your needs. Your needs come first in our client focused culture.


Lastly, in our firm philosophy, we are guided by the commitment to represent our clients zealously in the most cost effective manner, without sacrificing quality. To that end, we strive to be proactive, not reactive. In order to fulfill our philosophy, we are committed to make an early determination of the merits of each case in order to decide how a matter should be resolved. We realize that not every case should be settled, nor should every case be tried. By focusing on the commitment to provide sound advice and counsel on specific needs, we can offer solutions that make business sense.
