The new year promises change in Ontario’s civil litigation system as significant revisions to the Rules of Civil Procedure, RRO 1990, Reg 194 are expected to be finalized and come into force. Following release of the Phase 2 Consultation Report by the Civil Rules Review Working Committee in April 2025, and feedback that has been provided since then, an Implementation Committee has now been struck.
