Mathers McHenry & Co. is a Toronto firm that focuses on employment law and related commercial litigation. Founder Jennifer Mathers McHenry started the firm in 2019 after spending over a decade at another Toronto firm, making partner there in its executive employment law group, following an earlier stint as a commercial and employment litigator at a different Toronto firm. Mathers McHenry was called to the Ontario bar in 2005 and holds a law degree from the University of Windsor and an LL.M. from the University of Toronto. The firm acts for and with executive and senior employees, employers, business owners, and shareholders, and it has since grown to include partner Devin Jarcaig and associates including Emma Parry and Lauren Mazzuca.
The practice covers employment advice for both employees and employers, employment and commercial litigation, appeals, workplace investigations into harassment, discrimination, or policy violations, and mediation of workplace disputes. Its lawyers have appeared before administrative boards and tribunals, all levels of court in Ontario, and the Supreme Court of Canada. The office is at 36 Toronto Street, Suite 920, in the city's downtown core.

Who handles what
The neighbourhood
Mathers McHenry & Co.'s office sits in the Excelsior Life Building at 36 Toronto Street, a heritage tower designed in 1914 by E.J. Lennox. The building is protected under the Ontario Heritage Act and sits within the St. Lawrence Neighbourhood Heritage Conservation District.
Toronto Street itself was one of the city's original corporate and financial addresses in the late 19th and early 20th centuries, and 36 Toronto Street still combines the 1914 Lennox building with the 1874 Millichamps Building next door, joined by a shared atrium added in a 1986 to 1987 renovation. It's a fitting setting for a firm built around long-tenured client relationships in a historic pocket of downtown Toronto.
