The neighbourhood

The firm's office is in the Dynamic Funds Tower at 1 Adelaide Street East, on the corner of Yonge and Adelaide in downtown Toronto. The 30 storey building sits at the edge of the city's financial and legal core, an area built around the banks, corporate offices, and larger business law firms that a practice advising on business sales, contracts, and company structure regularly deals with.

It's a dense, walkable part of downtown, with the King subway station and the PATH underground concourse both close by, useful for clients coming from elsewhere in the city or the region for a meeting.
