Thomas MacKay

Windsor Divorce Lawyer, Collaborative Family Lawyer and Aspiring Family Law Mediator

“In my practice, I often meet the best people at the most challenging times in their lives. Navigating through divorce and separation is a complex journey, and my role is to guide with empathy and understanding. My advice is simple: find a lawyer who listens, collaborates on a plan tailored for you and your family, and never lose faith in your resilience.

Biography

Thomas MacKay stands at the forefront of family law in Windsor, Ontario, bringing a wealth of knowledge and experience gained since earning his Juris Doctor from the University of Windsor in 2011. As a member of the Ontario Bar, Thomas has dedicated his legal career to helping clients navigate the complexities of separation and family law.

His practice encompasses a comprehensive range of family law matters, including complex family law litigation and appeals, divorce and separation, parenting disputes, child and spousal support, property division, and separation agreements.

Known for his innovative thinking and ability to resolve emotionally charged issues, Thomas combines strong advocacy with practical, straightforward advice. His approach is client-centred: he takes the time to understand each client’s circumstances, priorities, and goals, and develops a strategy tailored to their family and their future.

Thomas’s practice includes family mediation and Collaborative Family Law, providing clients with alternatives to traditional court proceedings when appropriate. He believes that many separating spouses can achieve better and more durable outcomes by focusing on interests, exchanging information openly, and working toward practical solutions rather than approaching separation as a contest to be won.

Through Collaborative Family Law, Thomas works with clients and their collaboratively trained professionals in a structured, transparent process designed to resolve the legal, financial, and parenting issues arising from separation without going to court. The collaborative process allows clients to receive independent legal advice and advocacy while maintaining a shared commitment to reaching a negotiated resolution.

Thomas also provides family mediation, helping separating spouses identify the issues that need to be resolved, improve communication, explore possible solutions, and work toward mutually acceptable agreements. His training in negotiation, conflict resolution, communication, and family and domestic violence complements his experience as a family lawyer and informs his approach to dispute resolution.  While he is still working towards accreditation, he continues to be supervised by an experienced accredited family law mediator. 

Thomas recognizes that no single process is appropriate for every family. His practice therefore encompasses litigation, negotiation, mediation, and Collaborative Family Law, allowing him to help clients choose an approach that reflects the complexity of their case, the dynamics of their family, and their individual objectives.

Whether a matter requires determined courtroom advocacy or a cooperative approach focused on settlement, Thomas’s goal is the same: to provide clear advice, develop an effective strategy, and help clients move through separation toward a workable and positive new beginning.
