"Rewriting the Canadian Constitution" Class Ottawa in April 2017. The course was taught by Profs Johanne Poirier (McGill) and Daniel Turp (UdeM), and enrolled students from both universities.


Above: Twenty-six law students from Université de Montréal and McGill University spent the 2017 winter term writing the text of the (new) Canadian Constitution 2017 in a course taught by Professors Johanne Poirier (McGill) and Daniel Turp (UdeM). The class ended with a simulation of a Constituent Assembly in Ottawa.

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

2019-2021 Research project funded by the Secrétariat du Québec aux relations canadiennes

In 2019-2021, 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.

New publication: Le fédéralisme coopératif comme terrain de jeu du droit

mikado game

Professeur Johanne Poirier, MacKell Chair in Federalism at McGill University, and Professor Nicolas Levrat, Global Studies Institute, Faculty of Law, University of Geneva, have edited a special edition of the Fédéralisme - Régionalisme (volume 18: 2018) journal that examines the operation of the federal systems of Belgium, Canada, Switzerland and the European Union through the lens of games.

The studies presented in this volume are the result of cooperation between three French-speaking universities outside of France: the University of Geneva, the Université Libre de Bruxelles and the Université de Montréal, which in 2013 instituted the G3 of the francophonie. This consortium mainly supports the creation of research groups between partner universities. Thus was formed a "study group on public policies in the framework of cooperative federalism". Interestingly and unintentionally, it immediately became apparent that the countries in which the G3 partner universities (Belgium, Canada and Switzerland) are located are Federations that implement cooperative federalism in various forms. The issue is open access.

The Challenges of Coexistence: Language Policy in Canada

22 February 2019, 13:00-17:00, McGill Faculty Club


Much has been written recently about language policy in Canada, in light of political developments in provinces like New Brunswick and Ontario, the 50th Anniversary of the Official Languages Act and the announced recognition of Indigenous languages in Canada. The objective of this Symposium is to discuss language policy in Canada, with a particular emphasis on language minorities. The event focuses on Canada’s two official languages and their fate at the federal and provincial levels while also bringing to the fore issues related to other languages present in Canada, including Indigenous languages.
