About Matrona Law

Matrona Law Professional Corporation is a small litigation firm working out of an office on University Avenue in downtown Toronto's financial district. Niki Kanavas founded the firm in 2018 after spending nearly a decade in law and academia, and still runs it as a sole practitioner. The practice focuses on corporate and commercial litigation, construction law, and real property disputes, and it also takes on appeals, representing clients before the Divisional Court, the Ontario Court of Appeal, and the Federal Court of Appeal in intellectual property matters. Real estate transactions, as opposed to real estate disputes, are handled in affiliation with a related firm, Kanavas Law.

Kanavas earned an Honours BA in 2005, studied English and European law in the United Kingdom on the way to a law degree completed in 2011, and finished a Master of Laws in San Diego in 2015 with a focus on civil litigation, intellectual property, and pharmaceutical law. Since 2015, Kanavas has also taught as a professor at Seneca Polytechnic and contributed to legal textbooks, and serves as of counsel at Goldmans LLP alongside running Matrona Law. The firm's own name traces back to Kanavas's first name, Matrona.

The neighbourhood

Matrona Law's office sits at 55 University Avenue, at the corner of University and Wellington in Toronto's financial district, a stretch of the city dominated by bank towers and corporate head offices. The building connects directly to the PATH network and to St. Andrew subway station, so clients coming from elsewhere in the city by transit can reach the office largely underground.

Litigation work tends to lead to court, and University Avenue runs straight to it. Further up the same street sits the Toronto Courthouse at 361 University Avenue, a branch of the Ontario Superior Court of Justice that hears criminal and family matters. For a firm built around corporate, commercial, and construction litigation, that's a genuinely practical spot to be based.

Frequently asked questions

Can Matrona Law help me buy or sell a home in Toronto?
Matrona Law's own practice is litigation, but the firm handles residential real estate transactions in affiliation with a related firm, Kanavas Law. Where a real estate deal has already gone wrong, such as a failed purchase or a boundary dispute with a neighbour, Matrona Law represents clients directly.
I'm a homeowner in a dispute with my contractor. Can Matrona Law help?
Yes. The firm represents both homeowners and contractors in construction disputes, including payment disputes and claims involving property rights.
My commercial landlord (or tenant) and I disagree about our lease. Does the firm handle that?
Yes, Matrona Law represents both landlords and tenants in commercial leasing matters, from the first negotiation of the offer to lease through to the inception of the lease agreement itself.
Does Matrona Law handle appeals?
Yes. The firm represents clients on appeals to the Divisional Court, the Ontario Court of Appeal, and the Supreme Court of Canada.
How does Matrona Law bill for its services?
The firm bills by the hour for most matters, with flat fees available for certain contracts and negotiations. Effective January 2023, Matrona Law no longer offers free consultations, and it doesn't take cases on a contingency fee basis.
Can I meet with the lawyer in person?
Meetings are by appointment only, Monday to Friday, and the firm prefers telephone or video conferencing over in person visits.
