Saharkhiz v. Underwriters, Members of Lloyd’s London, (2000), 49 O.R. (3d) 255 (Ont. C.A.) and (1999), 46 O.R. (3d) 154 (Ont. S.C.J.), affirmed

The Court of Appeal upheld the motion judge confirming that our client, a taxi driver, who was terribly beaten while arguing over the fare, suffered catastrophic injuries in an “accident” as defined by the Statutory Accident Benefits Schedule.

941807 Ontario Ltd. v. Lennox Drum Ltd., 2003 CanLII 31888 (ON SC) and 180 OAC 95 (Ont. Div. Ct.)

Punitive damages awarded to our client arising out of bad faith in the execution of a commercial transaction. The Divisional Court upheld the trial judge’s decision in favour of our client.

Salvador v. Mather, 41 O.R. (3d) 289, 37 C.P.C. (5th) 214 (Ont. Div. Ct.)

The Divisional Court granted our client the authority to set aside an order that she consented to dismissing her action that was obtained while she was represented by another lawyer. Mr. Himelfarb argued successfully that the client could not have legally understood that she had a valid cause of action at the time her previous lawyer agreed to abandon the case. Accordingly, the client was permitted to set aside the dismissal order and proceed with her case for compensation.

Subramanian v. Shetler, 2002, 61 O.R. (3d) 136 (Ont. Div. Ct.)

The Divisional Court refused the appeal of the Defendants who were ordered to enter defences in Ontario and enure to the jurisdiction of the Ontario Courts, when they were American and the accident occurred in America. The court in Ontario was convinced that the balance of convenience favoured our client’s jurisdiction.

Whiting v. Menu Foods Operating Limited Partnership, 2007 CanLII 43903 (ON SC)

In this class action case, Mr. Himelfarb’s legal team was granted class counsel status, permitting and authorizing them to proceed and eventually settle this well known class action involving tainted pet foods.

New Generation Drywall Inc. v. Ontario (Minister of Finance), [2004] O.J. No. 465 (S.C.J.)
Our client was successful at trial in a taxation case that had precedent ramifications for the drywall and acoustic ceiling tile industry in Ontario. The court adopted Mr. Himelfarb’s argument that residential drywall workers were not employees for the purpose of deducting and withholding Employers’ Health Tax.

Decision No. 410/10, 2010 ONWSIAT 631, (Workplace Safety Insurance Appeals Tribunal)

In this decision, Mr. Himelfarb won his client loss of earning benefits retroactive to 1991, for a sum of approximately $700,000.00.
