The November 2013 issue of the Canadian Bar Review features two articles that deal with ethics:
“Settlement Conferences and Judicial Role: The Scaffolding for Expanded Thinking About Judicial Ethics” by Michaela Keet & Brent Cotter
“Solicitor-Client Privilege for Ethics Counsel: Lessons for Canada from the United States” by Stephen G.A. Pitel & Jordan McKie
The table of contents is at the link below but I think the articles themselves require a subscription to access.
