The neighbourhood

The office is in Law Chambers, a shared legal office suite provider, at 181 University Avenue, at University and Adelaide, in Toronto's Financial District. The building sits on University Avenue, the same downtown avenue that runs past Osgoode Hall and the Toronto Courthouse, and it's accessible from St Andrew subway station and directly on the PATH.

Law Chambers rents private offices and support services built for lawyers and small legal practices, the kind of arrangement that lets a solo litigation practice operate out of the downtown core without a traditional standalone firm office.
