About Tenant Lawyer Professional Corporation

Tenant Lawyer Professional Corporation is a Toronto firm that represents tenants in landlord and tenant disputes across Ontario. Led by Samuel Mason, the practice offers legal opinions and consultations, demand letters, negotiation and mediation, representation at Landlord and Tenant Board hearings, and appeals to the Divisional Court.

Samuel Mason, the lawyer behind the firm, has also worked as a staff lawyer and clinic instructor at Parkdale Community Legal Services, a community legal clinic in Toronto's Parkdale neighbourhood that focuses on housing rights. In March 2022, Mason co-wrote an article on Toronto renovictions, published by The Lawyer's Daily, with Cole Webber, a colleague at the clinic, arguing that vigorous representation of tenants at the Landlord and Tenant Board can discourage landlords from misusing renovation-based eviction notices. By August 2024, Mason had six years of experience as a tenant rights lawyer, split between the clinic and the firm, according to CP24.

Who handles what

The neighbourhood

The firm's office is inside the Centre for Social Innovation at 192 Spadina Avenue, a coworking hub for nonprofits and social enterprises. The building, known as the Murray Building, is a 1920s brick-and-beam structure. The Toronto Tool Library, a nonprofit lending library for tools, operates on the ground floor.

The building sits on Spadina Avenue just south of Queen Street West, between Kensington Market and Chinatown, in a stretch of downtown Toronto known for independent shops, restaurants, and creative and nonprofit organizations. A shared workspace built around nonprofits and social enterprises makes a fitting home for a small, tenant-side legal practice.
