About Ayaz Mehdi Professional Corporation

Clients rate this firm highly on Google.

Ayaz Mehdi Professional Corporation is a small firm based on Commerce Valley Drive East in Markham, Ontario, built around its principal lawyer, Ayaz Mehdi, with articling students, law clerks and support staff filling out the team. The practice covers family law, criminal defence, civil litigation, and wills and estate litigation. The firm's website also lists service pages for dozens of communities across the Greater Toronto Area and beyond, from Toronto and Vaughan to Barrie, Newmarket and Hamilton, but the Markham address is the firm's only office with a street listing, so clients elsewhere should expect to arrange an appointment rather than visit a local branch.

Mehdi earned a law degree from Southampton Law School in England and is licensed to practice through the Law Society of Ontario. According to the firm's own biography page, the early part of that career included time at a mid sized Toronto law firm gaining experience handling complex cases, followed by a partnership there, before opening an independent practice in Markham with more than a decade of legal experience behind it. The firm's site lists memberships in the Criminal Lawyers Association, the Ontario Trial Lawyers Association, the Family Lawyers Association, the South Asian Bar Association, the Toronto Lawyers Association, the York Region Law Association and the Canadian Bar Association.

The neighbourhood

The Markham office sits on Commerce Valley Drive East, in a stretch that runs along Highway 7 between Highway 404 and Bayview Avenue. Local neighbourhood data describes the eastern part of that strip as businesses and restaurants, with condo towers and townhomes further west, and names professional, scientific and technical services alongside finance and insurance as the area's two largest industries, so most of what surrounds the office is other commercial and professional tenants rather than retail storefronts.

That same data describes the surrounding community as highly multicultural, with residents tracing to dozens of countries of origin and sizeable Chinese and Iranian populations. For clients travelling in from elsewhere in the GTA, the area has a Langstaff GO station and close to a hundred transit stops nearby, on top of direct highway access from the 404, 407 and 7, which fits a practice whose client base is spread across many towns rather than concentrated in one.
