Main Street Relationships, Bay Street Results.

Over a span of more than four decades, O’Connor MacLeod Hanna has become the largest law firm in the Halton Region (Burlington/Oakville/Milton/Halton Hills).  A tradition of excellence has developed as OMH has grown with the communities it serves. While immensely proud of our past, a new generation of lawyers at the firm ensures continued success well into the future.

Helping clients achieve their personal and business goals has always been a priority at OMH.  Many of the people we serve have been with us for years, some being the grandchildren of original clients.  Unlike some large firms, OMH is able to turn on a dime responding to the changing requirements of clients - without the hassle and expense of travelling downtown. With lawyers and contacts across Canada, many U.S. states and overseas, we can address all of your legal requirements. Client requests are met with a warm smile in a friendly, professional environment.

We’re proud to share our experience and expertise with the community.  Community service throughout the Region and beyond is something we take very seriously at OMH. Let us know how we can help.

Firm History

O'Connor MacLeod Hanna's community roots span four decades of helping clients in Halton, Oakville, Burlington, and Milton to achieve their goals.

The foundation of the firm was built upon the merger in 1991 of two Oakville firms, O'Connor Leitch Hays and MacLeod Knox Watts. Independently, each firm had grown to be the two largest law firms in Oakville with a history of more than 20 years.
