Achieving successful outcomes

National and global clients frequently seek our skilled counsel on all issues related to the Supreme Court, including:

  • Whether and how to seek leave to appeal or how to respond to an opponent’s application for leave
  • The preparation of persuasive arguments and written materials that comply with the Rules of the Supreme Court of Canada
  • Service and filing of all materials required by the Court
  • The filing of motions before the Court (to stay proceedings, to admit new evidence, for extensions of time, to state constitutional questions)
  • Associated agency services

Our lawyers can also assist counsel with the preparation and delivery of oral arguments before the Court, or act as counsel or co-counsel as required on a particular case.

Expertise and insight

Gowling WLG's Supreme Court of Canada professionals are unsurpassed experts in their field. Led by D. Lynne Watt, the team includes partners, associates and clerks with extensive expertise in Supreme Court advocacy and agency services.

Members of our group are the authors of the Supreme Court of Canada Practice, published by Carswell. Now in its fourteenth edition, the book is the only publication to provide a fully annotated review and analysis of changes to the Supreme Court Act and Rules, and has been cited by the Court in several significant decisions.

In addition, our professionals prepare the Supreme Court Bulletin — a newsletter delivering immediate updates on all judgments and leave applications decided by the Court as well as all federal judicial appointments. It also provides periodic insight into recent Supreme Court judgments and practice matters. To receive this newsletter, visit our subscribe page.
