A High‑Level Summary Of Ontario's Proposed "Up‑Front Evidence Model" For Civil Discovery

Ontario civil litigation is set for a major reset in how parties prepare and exchange evidence. This summary explains the proposal to shift discovery towards an "up‑front evidence model", why the Working Group says it is needed, what was first proposed, what the consultation revealed, how the proposal evolved, and the benefits the Working Group expects—so you can see the direction of travel and prepare your clients and files accordingly.

Introduction

The Working Group frames discovery around a core principle of natural justice: the right to know the case to be met. In Ontario's current model, that right is delivered through broad documentary discovery and oral examinations—steps that now drive cost and delay. The proposal reimagines discovery, so parties still know the case they must meet, but in a more pragmatic and proportionate way that reduces time and expense while preserving procedural fairness.
