Securities Litigation

Lenczner Slaght has extensive experience in litigating securities-related disputes before the courts, including the defence of professional negligence and other claims brought against investment advisors and dealers and significant expertise defending shareholder class-action proceedings.

Our lawyers also appear regularly in the hearing rooms of the provincial securities commissions including the Ontario Securities Commission, as well as the Investment Industry Regulatory Organization of Canada (IIROC) and the Mutual Fund Dealers Association (MFDA), defending clients' interests against allegations of breaches under various legislative and regulatory frameworks, including: 

  •          the Ontario Securities Act
  •          IIROC Dealer and MFDA Member Rules
  •          Universal Market Integrity Rules (UMIR)

Our lawyers are active in securities policy, including membership on the Ontario Securities Commission’s Securities Proceedings Advisory Committee.

We also help clients conduct internal corporate investigations relating to potential breaches of securities and other laws either prior to, or in conjunction with, inquiries by regulatory authorities. 

In any securities matter, we recognize that the best outcome typically avoids regulatory proceedings – and adverse media attention – altogether. To that end, we provide strategic counsel and advice to registrants, investment advisors, securities lawyers and other market participants, both before and during investigations.  Where it cannot be avoided, we have the advocacy experience to defend any contested regulatory hearings.
