About Yazdani Law Office

Yazdani Law Office is a Toronto disability law firm that represents people across Ontario in disputes with their disability insurers, focusing on long term disability claims that have been denied or cut off. Mehran "Mark" Yazdani leads the firm, graduated from Osgoode Hall Law School in 2003 and was called to the Ontario bar in 2004. Before taking on plaintiff-side work, Yazdani practised as a commercial litigator at Lang Michener LLP and later as in-house counsel for RBC Insurance, managing disability litigation from the insurer's side. Yazdani Law Office Professional Corporation was founded in 2009 and now handles claims involving fibromyalgia and chronic pain, psychiatric conditions such as depression, anxiety and PTSD, and short term and long term disability benefit denials, along with some life, mortgage and critical illness insurance disputes.

Yazdani personally handles every aspect of each case from the first meeting through settlement or trial, and the office aims to return every call or email within 24 hours. Cases are taken on contingency, with no upfront legal fees, and the firm offers a free consultation that includes a review of the client's complete disability file. Clients who have trouble travelling because of their condition can be met at home instead. Yazdani belongs to the Ontario Trial Lawyers Association and is listed by Lexpert as Consistently Recommended in Long-Term Disability law.

The neighbourhood

Yazdani Law Office's office is in a highrise at 5000 Yonge Street, in the North York Centre area, near the North York Centre subway station. Since the firm represents disability claimants from across Ontario rather than a local walk-in clientele, the Yonge Street address works mainly as a home base: clients who have trouble travelling are offered home visits, and the firm keeps satellite meeting locations elsewhere in Toronto (Yonge and Eglinton, downtown, Yorkville and Scarborough) as well as in Mississauga, Oakville, Vaughan and Hamilton.

Frequently asked questions

My long term disability benefits were denied or cut off. Can Yazdani Law Office help?
Yes. The firm exclusively represents disability claimants against their insurers and can take the case to court to try to recover the benefits owed, plus interest and other damages.
Does the firm handle fibromyalgia and chronic pain claims?
Yes. Fibromyalgia and chronic pain, including orthopedic conditions like disc herniation, are among the firm's main areas of focus, since insurers often deny these claims for lacking objective medical evidence.
I'm dealing with depression, anxiety or PTSD and my disability claim was denied. Can Yazdani Law Office take my case?
Yes. The firm represents claimants with psychiatric disabilities, including depression, anxiety, bipolar disorder, PTSD and panic disorder, and can arrange an independent psychiatric assessment as part of the case.
What does it cost to hire Yazdani Law Office?
There are no upfront fees. The firm works on a contingency basis, so it's paid a percentage of the recovery only if the case settles or succeeds at trial, and it offers a free consultation to review a claimant's file before taking it on.
I can't easily leave my home because of my disability. Can I still meet with a lawyer?
Yes. Yazdani Law Office offers home visits for clients who aren't able to come into the office, meeting at the client's home or another location they choose.
Where is Yazdani Law Office located and does it serve clients outside Toronto?
The firm's office is at 5000 Yonge Street in Toronto, with satellite meeting locations across the GTA and in Hamilton. It serves clients across Ontario and can be reached by phone.
