About Us

A Storied Past, A Promising Future.

O’Connor MacLeod Hanna LLP has now entered its fifth decade of helping clients meet their business and professional goals.  Proudly, OMH continues to grow along with the communities it serves.

It was in 1991 that Oakville’s two most formidable law firms decided that they could better serve the rapidly expanding community by joining forces. Each with twenty years experience, O’Connor Leitch Hays and MacLeod Knox Watts merged.  Emerging areas of law could now be addressed along with conventional practice.

Just nine years later, there was further growth. With increased specialization in law, veteran Oakville lawyer Brian Hanna decided his clients would receive better service through a larger firm. The two firms joined together to become O'Connor MacLeod Hanna LLP.

OMH is proud to be thought of as a full-service law firm offering decades of experience and expertise in a wide variety of practice areas. Clients know that they can easily access seasoned professionals in a warm and welcoming environment.  

While the OMH history is impressive, it sets a standard of excellence that is sure to continue as the firm looks to the future.
