Mark is a dedicated advisor and fierce advocate who ensures that conflicts are dealt with effectively and economically for his clients. His reputation as a leading Canadian litigator has led to numerous accolades by several national guides to the legal profession, including The Canadian Legal Lexpert Directory (Leading Lawyer to Watch in the area of Corporate and Commercial Litigation), Benchmark Litigation (40 & Under List, Litigation Future Star) and Thomson Reuters Stand-Out Lawyers.

Mark is a member of the firm's Litigation and Financial Services Groups, practising a broad range of corporate, commercial and financial services litigation. Mark’s clients have included public, private, and not-for-profit corporations, partnerships and joint ventures, financial institutions, court-appointed receivers, charitable organizations, directors and officers, shareholders, sole proprietors, and individuals and small and large businesses across a wide array of industries. 

Whether through litigation or negotiation, Mark will do whatever it takes to deliver the best possible solutions, in the time frames required by his clients to best meet their needs and objectives. Mark provides comprehensive support to guide his clients to satisfactory outcomes when disputes arise, and to best position his clients for litigation where resolutions cannot be achieved at an early stage.

Mark has extensive experience litigating corporate and commercial disputes, often involving contract, fraud and other torts, negligence and allegations of oppression.  Mark has served in the capacity as court-appointed Representative Counsel for a body of unit holders in receivership proceedings commenced under the Ontario Securities Act, as well as for the court-appointed Receiver in receivership proceedings commenced under the Ontario Securities Act.  Over the years, Mark has also developed a niche for obtaining urgent injunctive relief from the Ontario Superior Court of Justice on behalf of his clients, often in cases involving fraud, and in other circumstances where his clients require immediate relief from the court. This can include enforcing the terms of an existing contractual arrangement, to prevent a cessation of services by the defendant which would cause irreparable harm to a client’s business, or freezing the assets and accounts of defendants who are alleged to have been the beneficiaries of misappropriated funds.  Mark also has experience acting as the Independent Supervising Solicitor with respect to the execution of an Anton Pillar Order. 

In addition to his extensive litigation practice, Mark has also successfully represented University students in academic appeals and disciplinary proceedings under University policies in Ontario.

As part of his litigation practice, Mark regularly attends to argue motions before the Ontario Superior Court of Justice (Civil and Commercial List Courts). Mark has conducted trials at the Ontario Superior Court of Justice, appeals at the Ontario Court of Appeal, and has prepared leave to appeal applications to the Supreme Court of Canada. Mark is a regular participant in private and court-mandated mediations, and also has experience successfully litigating disputes through private arbitration.  

Throughout his career, Mark has served as a firm-appointed mentor to summer and articling students who aspire to practise in the area of corporate and commercial litigation, as well as to associate lawyers in the firm’s Litigation Group. Mark is a longstanding member of the firm’s Student Recruitment Committee.
