A Canadian leader in class actions, Lenczner Slaght is one of the only firms in the country to have repeatedly litigated on behalf of defendants at the trial level. Our lawyers' class actions expertise has been sharpened through hands-on experience in a wide range of complex and technically demanding proceedings.
Our firm has defended many of Canada's most closely watched class action lawsuits over the past three decades. For example, we successfully represented Danier in Kerr v Danier Leather Inc – from the outset of the action through to the groundbreaking decision at the Supreme Court of Canada.
