AI-powered analysis

Answers grounded in the treatise

Every section has been analyzed by most advanced AI model. In independent testing using adversarial questions drawn directly from the treatise, the AI achieved a near perfect resolution rate — correctly identifying the applicable rules and their limits without advance knowledge of the answers.

A near-perfect resolution rate means the AI understands the treatise correctly and applies it correctly. This extends to scenario resolution: given a specific factual situation, the AI identifies which rules govern it, how they interact, and what outcome follows — reaching conclusions consistent with what the treatise itself establishes. The testing confirms that these resolutions are compliant with the treatise rules, not merely plausible.

Every answer can be researched and validated. Each AI statement cites the specific treatise sections it relies on — sections presented here with full discussion of the rules applied. Supporting materials are integrated throughout: 850 CRA interpretations and rulings accessible within the treatise itself, plus cases and other documents available through direct links.

The treatise viewer provides two AI modes. The Scenario Resolver accepts fact situations — parties, events, dates and amounts — and applies 13 interpretive rules in a structured two-phase analysis. Phase 1 assembles the applicable rules, verbatim treatise quotes and any gaps in the law. Phase 2 produces the resolution: income inclusion, deductions and withholding obligations, with each conclusion labelled [SETTLED], [BETTER VIEW] or [UNRESOLVED]. It resolves the most complex multi-event, multi-party scenarios and proposes follow-on variations after each analysis.

The Research Assistant answers questions about rules, concepts and statutory provisions — covering the statutory framework, CRA administrative position, relevant caselaw, contested points and planning implications. Both modes load the complete treatise as a single context for every query, so no relevant section is missed, and respond in the subscriber's selected language, English or French.

About the author

Paul B. Singer

Paul B. Singer graduated from the law faculties of McGill and Oxford where he studied as a Rhodes Scholar. He worked in the Privy Council Office of Canada, taught tax law as a full-time professor and wrote a multi-volume treatise on corporate reorganization which he later edited for over 10 years, joined the tax group of one of the largest law firms in Canada where he practiced tax law for fifteen years as an equity partner and vice-chair of the tax section and contributed many featured articles in specialized tax publications notably in the area of international branch tax planning and executive compensation, and then acted as founder or investor in ventures including publishing and software development.

In 2026 he released a tax treatise entitled Management Incentive Taxation which is AI-enabled and includes a breakthrough resolver capable of applying treatise rules to the most complex problems without drift. This is the culmination of a project undertaken in 2020 with the publication of Equity for Management, of which the second edition was released in 2022 — alongside which he and his team began developing a method for fully automated retrieval, years ahead of the AI tools available at the time. When models with sufficient context capacity arrived in late 2025, that method fused naturally with the new capability; near-perfect accuracy followed only once the procedure, refined on earlier models, was confirmed to hold without exception on the model generation released in February 2026. This treatise and its companion newsletter have been widely consulted by tax professionals in law, accounting and business, including most major tax firms (eg Stikeman, Davies, EY, etc.). In its current edition, the work comprises more than of 1,250 pages of original commentary continuously updated with the latest CRA documents, cases, and writing by tax experts. The AI-enabled treatise is disseminated both as a subscription service and a newsletter which together reach the full spectrum of tax and compensation professionals.

Besides providing planning guidance, the service aims: -to describe the challenges to the rule of law caused by excessive administrative discretion; -to develop proposals for legislative reform and tax simplification, including the codification of current law and practice; and -to initiate the revision of plans and arrangements through initiatives such as the standardization of “change-in-control” provisions, in which several firms participate.
