About OneLegal Professional Corporation

OneLegal Professional Corporation is a family law firm based in Thornhill, Ontario, with a second office on Bay Street in downtown Toronto. Founder and principal lawyer Negin Shahraki set the practice up to handle divorce and separation, parenting and decision making responsibility, child and spousal support, division of property, and Family Responsibility Office matters, along with adoption, grandparents' rights, and Children's Aid Society cases. The firm also represents landlords and tenants in disputes before Ontario's Landlord and Tenant Board and helps entrepreneurs apply for permanent residency through Canada's Start-Up Visa program.

Shahraki holds a Juris Doctor from the University of Windsor and an MBA from Carleton University, plus a Bachelor of Arts with Honours in Political Sciences and International Studies from the University of Warwick and graduate degrees in international relations from Queen's University and the University of London. Shahraki is a Chartered Business Valuator trainee, a background the firm says supports the financial side of separations involving business owners, and completed a family mediation certificate at York University that underpins the firm's mediation and collaborative work. The firm serves Farsi speaking clients and is listed on Legal Aid Ontario's roster for family and child protection matters.

The neighbourhood

OneLegal's main office is at 505 Highway 7 in Thornhill, a community that straddles the Vaughan and Markham boundary in York Region. Highway 7 there is a busy commercial corridor of multi-tenant office buildings serving the surrounding suburbs, some distance from the older downtown cores of Markham and Vaughan.

The firm's second office is on Bay Street in Toronto's Financial District, giving clients downtown a place to meet without a trip out to York Region for every appointment. It's a useful pairing for a firm whose clients come from both the city and the 905 suburbs around it.
