The neighbourhood

The firm works out of 101 Randall Drive, a unit in a north Waterloo business park near Northfield Drive, the kind of low-rise glass-and-brick office cluster that grew up around the region's technology sector. The firm itself points to its spot in the heart of Canada's Technology Triangle, and the setting fits a practice that does a lot of corporate, commercial, and business and financial services work for local companies. Parking is free onsite, which is a practical thing for clients driving in from Kitchener, Cambridge, and the surrounding townships. From here the firm handles files across Waterloo Region and out into the rest of Ontario.
