About Miller Thomson LLP

Miller Thomson LLP is a national business law firm, founded in 1957 and headquartered in Toronto. It runs ten offices across Canada, from Vancouver and Calgary through Saskatoon, Regina, London, Vaughan, and Toronto to Montréal. The work covers a full range of business and personal legal services: corporate and commercial matters, litigation and dispute resolution, real estate, tax, labour and employment, intellectual property, and wills, estates and trusts.

The Waterloo Region office sits in the heart of Uptown Waterloo, at 115 King Street South, and it isn't a recent satellite. It traces its roots to 1858, when W.H. Bowlby opened a law practice on King Street in what was then Berlin, now Kitchener. That gives it more than 150 years of continuous work in the community, a lineage that predates both Confederation and Miller Thomson itself. Today it's among the larger firms in Waterloo Region, a local practice with deep local roots that also happens to be part of a national firm.

The neighbourhood

The office sits at 115 King Street South, in the heart of Uptown Waterloo. King Street is the district's main commercial corridor, running through the historic core near King and Erb, where the city was first settled, and continuing south into Kitchener. There's a neat continuity in the address: the firm's Waterloo lineage started with a King Street practice back in 1858, and more than 150 years later its successor still keeps a King Street door. Uptown itself is a walkable mix of shops, restaurants, and century-old commercial blocks, with Waterloo Park a short walk to the west.
