The neighbourhood

Ellyn Law's office is in the DBRS Tower at 181 University Avenue, part of the Adelaide Place complex, a Class A office property built in 1975 and connected directly to Toronto's PATH network.

The same street is home to Ontario's Superior Court of Justice civil courthouse at 330 University Avenue, which handles civil trials along with bankruptcy, commercial and estates matters on separate floors, a fitting neighbour for a firm built around business litigation and arbitration.
