Law practice and academic career
Alarie’s scholarly research examines taxation law, judicial behavior, and the practical implications of artificial intelligence in legal decision-making. [9] [10] In 2003, Alarie began his legal career as a law clerk for Madam Justice Louise Arbour at the Supreme Court of Canada.
In 2004, Alarie joined the University of Toronto’s Faculty of Law as a full-time professor. He has taught courses in tax law, constitutional law, and law and technology, and was awarded the Alan Mewett QC Prize for excellence in teaching by the law school’s graduating class in 2009. Alarie is also an affiliated faculty member of the Vector Institute for Artificial Intelligence [9] and the Schwartz Reisman Institute. [6]
He is a co-author of several editions of a textbook on tax law, Canadian Income Tax Law. [11] [12] In 2016, he introduced the concept of the “legal singularity,” describing the potential for artificial intelligence to improve the coherence and consistency of legal systems.
He later co-authored the peer-reviewed books Commitment and Cooperation on High Courts (Oxford University Press, 2017) [13] and The Legal Singularity: How Artificial Intelligence Can Make Law Radically Better (University of Toronto Press, 2023). [14] These publications examine themes of artificial intelligence, institutions, and justice. Alarie is under contract with Oxford University Press to publish his third university-press monograph, Superjustice, forthcoming in 2026.
Blue J
In 2015, Alarie co-founded Blue J, [15] alongside Brett Janssen, Anthony Niblett and Albert Yoon. Blue J is a Toronto-based company focused on applying artificial intelligence and machine learning to tax research. [16] [17]
In 2023, Blue J relaunched its platform as a generative AI tax research tool designed to provide citation-backed answers grounded in authoritative tax sources. By 2025, the platform was used by more than 4,000 organizations, including firms such as KPMG UK, Crowe, Larson Gross, and RCM, as well as several Fortune 500 companies. [18]
A central component of Blue J’s platform is its licensed content library, which includes agreements with Tax Analysts (publisher of Tax Notes) and IBFD [19] , enabling access to U.S. and international tax materials covering more than 220 jurisdictions.
In August 2025, Blue J raised a $122 million Series D funding round led by Sapphire Ventures and Oak HC/FT. [20] The funding supported continued product development and international expansion. That same year, Blue J was named one of Accounting Today’s Top Apps for Accountants. [21]
In September 2025, Blue J co-authored the AI Tax Research Solution Outlook Report in partnership with CPA.com, examining trends in the adoption of artificial intelligence in tax accounting. [22]
