About Musson Law Group

Musson Law Group is a Toronto based divorce and family law firm founded by Anna-Marie Musson. Its head office sits in Scotia Plaza at 40 King Street West, in downtown Toronto, and the firm keeps additional offices in Scarborough and two in Waterloo Region, one in St. Jacobs and one in Kitchener. So it's a Toronto firm that serves Waterloo Region from local offices, not a firm that started here. The founder began a legal career on Bay Street and was previously a litigation partner at a national law firm before building a practice focused on divorce and family law.

The work centres on divorce, and the firm takes on high net worth separations, property division and equalization, spousal and child support, and cohabitation and prenuptial agreements. Its stated aim is to settle matters without going to court, using collaborative law, mediation, and arbitration rather than litigation where it can. The firm also serves Chinese speaking clients under the brand Qin'an Divorce Law Firm (沁安离婚律师事务所), working in English and Chinese, and one of its lawyers acts as the firm's Chinese market representative.

The neighbourhood

The firm's Waterloo Region offices sit on two sides of the map. The St. Jacobs office is at 1440 King Street North, on the main corridor of a village in the township of Woolwich, just north of the city of Waterloo. St. Jacobs grew up around mills on the Conestogo River in the 1850s, and it sits in the heart of Waterloo Region's Old Order Mennonite country, with the year round St. Jacobs Farmers' Market a short drive south. The Kitchener office is at 501 Krug Street, Unit 203, which puts the firm within reach of clients closer to the region's urban core. The local tie isn't only an address either. One of the firm's lawyers has built up family law experience in Waterloo Region over the past decade.
