The neighbourhood

Watson Jacobs Bosnick's main office is on Yonge Street in Toronto, one of several office addresses along that stretch north of the downtown core. Because the firm's clients are trade unions, trust funds, and professional regulators rather than walk in individuals, its lawyers spend much of their time at hearings, arbitrations, and tribunal proceedings across the Greater Toronto Area rather than at the office itself.

The London office, on Central Avenue, extends that same union side and regulatory practice into southwestern Ontario. Partner Michael Klug has worked from that location since 2000, representing unions in the municipal, education, industrial, and transportation sectors across the region.
