About MSG Law
MSG Law is a Toronto sole practitioner civil litigation firm run by lawyer Susan Guzzo. It's based at 401 Bay Street, on the 16th floor, and works by appointment rather than walk in hours. The firm's work centres on general and commercial insurance litigation and civil litigation more broadly, acting for professionals, businesses, manufacturers, retailers, and municipalities that carry liability exposure, as well as for people bringing claims against them. It also gives strategic advice, reviewing insurance policies, procedures, and workflow to help clients reduce risk before a dispute starts.
Guzzo spent more than 20 years in civil litigation at established Toronto firms before opening this practice, appearing before the Superior Court of Justice, the Divisional Court, and the Court of Appeal for Ontario for clients in construction, health care, education, and other sectors. The firm calls its approach "Bay Street training, Main Street approach," and that's not just a slogan: growing up in Northern Ontario as the child of working class parents, before years of big firm litigation, shaped a practical, approachable way of handling disputes.

Who handles what
The neighbourhood
MSG Law's office sits in the Simpson Tower, at Bay and Queen Streets, a 33 storey building completed in 1968 as the head office of the Simpsons department store chain. Hudson's Bay Company later took over the tower in 1978 and kept its own head office there until 2025, and the building still connects directly into the Toronto Eaton Centre. That puts the firm in the heart of downtown Toronto's financial and retail core, where clients meet by appointment rather than during set office hours.
