Cooperative federalism, a presentation by Professor Poirier

Professor Johanne Poirier. On-screen text reads "Professeure Johanne Poirier, Chercheuse au CRIDAQ, Axe 2: Insititutions, justice sociale et territoires".

In this explanatory video by the Abécédaire du CRIDAQ, Professor Johanne Poirier presents cooperative federalism in the Canadian context. A concept which promotes negotiation, collaboration, and the acknowledgement of the respective interests between different orders of government, cooperative federalism has experienced a surge in popularity over the last 15 years, especially as a principle of constitutional interpretation.

Comparative Federalism and Covid-19: Combating the Pandemic

Couverture de l'ouvrage et 1re page du chapitre rédigé sur le Canada.

The Chair is happy to announce the publication of Nico Steytler (ed), Comparative Federalism and Covid-19: Combating the Pandemic (London: Routledge, 2021): With case studies from 19 federal countries, this collection explores the core elements of federalism that came to the fore in combatting the pandemic: the division of responsibilities (disaster management, health care, social welfare, and education), the need for centralisation, and intergovernmental relations and cooperation.

The authors adopt a multidisciplinary approach to question whether federalism has been a help or a hindrance in tackling the pandemic. Johanne Poirier and Jessica Michelin contributed the chapter on Canada, which is entitled “Facing the Coronavirus Pandemic in the Canadian Federation: Reinforced dualism and muted cooperation?”.

Publication of Canadian Federalism and Its Future / L’avenir du fédéralisme canadien

Nearly four years after the “Canada 150” conference, we are happy to announce that the collections are available in English and in French from McGill / Queen's University Press and from les Presses de l'Université Laval (2020).

"The time is ripe to revisit Canada's past and redress its historical wrongs. Yet in our urgency to imagine roads to reconciliation with Indigenous peoples, it is important to keep in sight the many other forms of diversity that Canadian federalism has historically been designed to accommodate or could also reflect more effectively. Canadian Federalism and Its Future brings together international experts to assess four fundamental institutions: bicameralism, the judiciary as arbiter of the federal deal, the electoral system and party politics, and intergovernmental relations. The contributors use comparative and critical lenses to appraise the repercussions of these four dimensions of Canadian federalism on key actors, including member states, constitutive units, internal nations, Indigenous peoples, and linguistic minorities. Pursuing the work of The Constitutions That Shaped Us (2015) and The Quebec Conference of 1864 (2018), this third volume is a testimony to Canada's successes and failures in constitutional design. Reflecting on the cultural pluralism inherent in this country, Canadian Federalism and Its Future offers thought-provoking lessons for a world in search of concrete institutional solutions, within and beyond the traditional nation-state."

Publication of Cinquante déclinaisons de fédéralisme: Théorie, enjeux et études de cas

Cinquante déclinaisons de fédéralisme: Théorie, enjeux et études de cas This French-language collection was co-edited by our postdoctoral researcher, Dave Guénette.

Cette collection de 50 brèves contributions de spécialistes internationaux "propose un apport d’une grande ampleur tout en se voulant le plus exhaustif possible. Il s’agit d’un ouvrage de référence qui expose clairement les concepts que les chercheurs en études fédérales mobilisent, les cadres d’analyse qu’ils emploient ainsi que les spécificités sociopolitiques qu’on observe dans les diverses structures fédérales existantes. Ce livre comprend également un glossaire constitué de cinquante notions clés, toutes définies de manière simple et usuelle. Faisant le point sur les débats contemporains, il a pour vocation d’initier les étudiants, les décideurs et le grand public à ce champ d’études en pleine effervescence."

This collection, published in 2020 by Presses de l'Université du Québec, is available in open access.

Cooperative Federalism and Intergovernmental Relations:
What's Law Got To Do With It?

2019-2022 Research project funded by the Secrétariat du Québec aux relations canadiennes

In 2019-2022, Professor Johanne Poirier will be leading a major research project on intergovernmental relations and cooperative federalism.

The technical ramifications and legal implications of intergovernmental agreements, as well as their implementation, have been generally neglected by jurists. However, cooperative mechanisms crafted by the executives can have undeniable collateral effects on the scope of parliamentary scrutiny over the executive, on judicial review of administrative action and on the balance of federal architecture.

Professor Johanne Poirier will attempt to fill these doctrinal gaps by studying the law that emanates from, structures and affects intergovernmental agreements. She also plans to initiate a form of “catalogue” of cooperative techniques and of the role played by law in structuring them. While the project is focused on cooperative federalism in Canada, it will benefit from a comparative lens: analysing foreign experience being so often the best way of decoding the particularities of one’s own system.

Ultimately, her work harbors significant potential to provide answers to the various components of the Canadian federations on the uncertainties inherent to the modalities of intergovernmental cooperation, on the stability of cooperative mechanisms and on the courts’ responses to them.

About the Chair

The Peter MacKell Chair in Federalism aims to reflect on the foundations, potential, risks and concrete incarnations of the “federal phenomenon” understood broadly.

The inaugural holder of the Peter MacKell Chair is Professor Johanne Poirier.

The Peter MacKell Chair in Federalism was created at the Faculty of Law thanks to a generous bequest from Peter R.D. MacKell.
