Each month, we tell you which five English-language cases and French-language cases have been the most viewed* on CanLII in the previous month and we give you a small sense of what the cases are about using CanLII-published AI-generated summaries of the case or case excerpts.

For this past month, the five most-consulted English-language decisions were:

1. Kerr v. Baranow, 2011 SCC 10

Facts: Two unmarried partners cohabit for about 12 years and have two children together. The female partner leaves employment to relocate and assumes most childcare and domestic labour while the male partner builds a . . . [more]

There’s plenty of evidence to suggest that outsourcing your cognitive processes to AI — whether by letting it do your writing or thinking or analyzing for you — is a bad idea. Partly, of course, this is because the AI might do a poor job of it, leaving you on the hook for badly reasoned arguments or banally worded text.

In the bigger picture, though, the worry is that by delegating your thought processes to a machine, your own cognitive muscles will atrophy, and you’ll be less able to apply acute reasoning when you don’t have the AI to rely . . . [more]

Mediators are often asked by parties or their counsel to send them a copy of their “standard Agreement to Mediate” for review. But is there such a document?

If by “standard” we mean some prescribed form followed by all mediators, the answer is no. Virtually every mediator has his or her own Agreement. Some are based on agreements provided in mediation training, while others are quite customized.

This article has its origin in a recent mediation. One of the three lawyers attending had clearly not read the Agreement to Mediate, although it had been sent to him weeks earlier. When . . . [more]

INTRODUCTION

The Ontario Court of Appeal’s (“CA”) recent decision in Knauff v. Ontario (Human Rights Tribunal) (“Knauff”) sought to resolve two CA panels’ disagreement about the continuing relevance of the test for leave to appeal in Sault Dock Co. Ltd. and City of Sault Ste. Marie (Ont. CA) (“Sault Dock”). (I considered the two CA decisions, West Whitby Landowners Group Inc. v. Elexicon Inc. [“West Whitby”] and Davis v. Aviva General Insurance Company [“Davis”] in my January 7, 2025 Slaw post, “Tension on the Ontario CA: Thwarting a Judicial Coup?”.) My focus . . . [more]

Professional services firms spend a lot of time developing strategy. There are leadership retreats, partner interviews, market assessments, client discussions and competitive reviews. There are conversations about growth, succession, technology, culture, new markets and the future of the firm.

Once the strategic plan emerges and the most significant priorities identified, the plan is presented to the partnership, everyone agrees, and then everyone goes back to work.

So why do so many firms that created a perfectly good strategic plan, struggle so much with execution? This is typically because the strategy exists at one level of the organization while the work . . . [more]

For Professor Seánna Howard, Director of the International Human Rights Advocacy Workshop, international legal research begins with a simple but important recognition: the most valuable sources are not always the most familiar ones. Her research has taken her to Tucson, where she joined the renowned Indigenous Peoples Law and Policy (IPLP) Program at the University of Arizona College of Law. Along the way, she has worked as an advocate, lawyer, researcher, independent expert, and educator on issues involving Indigenous Peoples, international human rights law, and social justice.

Her work also reflects the importance of developing research strategies for areas . . . [more]

Can a lawyer be disbarred for misconduct that is directly caused by mental illness? Until recently, my educated guess would have been no.

In May and June of 2026, a Hearing Panel of the Ontario Law Society Tribunal issued an important pair of decisions that carefully and deliberately resynthesize the role and impact of mental illness in lawyer regulation.[1] These decisions set out and apply a “unified approach” to alleged misconduct by lawyers where mental illness may be a factor.[2] At first glance, this new approach seems to reject case law, including case law by the Appeal Panel . . .

Preoccupation with the ongoing armed conflict in Iran has diverted attention from the grim aftermath of Iran’s nation-wide protests that began on 28 December 2025, during which tens of thousands of protestors were killed, arrested, or disappeared.

Lawyers were prevented from reaching their detained clients. Lawyers themselves were among those detained simply for trying to do their jobs. Protestors are now being tried without legal representation before courts that lack any semblance of independence or impartiality. Frequent executions are now being carried out following hasty and grossly unfair proceedings.

Dissidents who flee Iran may be subjected to transnational repression in . . . [more]

PÉNAL (DROIT) : Dans une affaire de voies de fait graves commises à l’endroit d’une inconnue à la sortie d’un bar, en se limitant à énoncer les conséquences indirectes de la peine et en les qualifiant de facteurs neutres, sans les analyser véritablement dans l’exercice de détermination de la peine, . . .
