David appears before both the trial and appellate levels of the Ontario Superior Court of Justice and the Federal Court of Canada.  He has also appeared before a number of administrative tribunals including tribunals such as the Ontario Energy Board and Alcohol Gaming Commission of Ontario.

David is experienced in domestic and international arbitrations and recently acted as lead counsel in proceedings brought before the ICC International Court of Arbitration.  He is also a member of the ICC Canada Committee.

David assisted the Honourable Bob Rae in his review of the bombing of Air India Flight 182 and in the preparation of his report entitled Lessons to be Learned which led to a Commission of Inquiry into the investigation of that event.  

He is always exploring new developments in the law.  In 2015, David spoke at a Law Society of Ontario program where he addressed the litigation risks associated with “crowdfunding”.
