On January 1, 2010 numerous changes were enacted to the Rules of Civil Procedure (the "Rules") that govern civil litigation in Ontario. Many of these rule changes are subject to interpretation by the Court. The full effect of the changes on personal injury litigation in Ontario will only become clear with the passage of time. Certainly the most pressing and important change for personal injury law clerks will be to ensure that all documents are filed on time for motions or applications and to ensure that actions are served and moved along promptly so that they are not subject to dismissal by the Registrar. It will also be important to ensure that discovery plans are filed and updated regularly and that all expert reports received comply with the new Rules.
