In a securities misrepresentation class action, the defendants brought a motion to strike the plaintiffs' reply expert report, delivered by Andrew M. Mintzer, in its entirety.
The report, initially intended to address causation, expanded to cover liability, contravening the agreed timetable and the rule against case-splitting.
The court granted the defendants' motion, striking the report but allowing the plaintiffs leave to file a new affidavit from Mr. Mintzer strictly confined to the issue of causation, as originally agreed.
The court emphasized the importance of adhering to timetables and the rule against case-splitting, particularly in leave motions under the Ontario Securities Act, which serve a gatekeeper function.
