Across the four dossiers, Deputy Minister Arianne Reza is documented exercising executive oversight at Public Services and Procurement Canada (PSPC) across four distinct administrative and operational portfolios:

1. Archival Proactive Disclosure: In dossier TGWR-240639, Reza is identified as Deputy Minister on August 6, 2026, overseeing the departmental publication of travel and hospitality records dating back to 2008 while PSPC manages active asset divestiture mandates.
2. "Buy Canadian" Procurement Outcomes: In dossier TGWR-055307, Reza, alongside Minister Joël Lightbound and Associate Deputy Minister Francis Trudel, oversaw the administrative execution of the "Buy Canadian" procurement policy between December 2025 and June 2026. During this period, over 70% of contracts were awarded to foreign-owned subsidiaries through the application of "substantial transformation" clauses qualifying vendors under a $5 million threshold.
3. Occupational Health Standards at Federal Real Estate: In dossier TGWR-209657, Reza is named as overseeing PSPC's formal rejection of employee remote accommodation requests at the Guy-Favreau Complex, maintaining the legacy Phase Contrast Microscopy (PCM) testing standard rather than the Transmission Electron Microscopy (TEM) standard requested by bargaining agents.
4. Structural Procurement Centralization: In dossier TGWR-256916, Reza is identified in PSPC’s 2026–27 planning documents as directing and executing a structural transition under the centralized "Buy Canadian" framework. This involved institutionalizing the Defence Investment Agency (DIA), implementing a "Build-Partner-Buy" model, removing Canadian International Trade Tribunal (CITT) jurisdiction over covered procurements, and lowering the strategic procurement threshold to $5 million by June 15, 2026.

Reading TGWR-055307 and TGWR-256916 together connects the administrative mechanism to its outcome under Reza's tenure: the $5 million strategic procurement threshold scheduled for implementation by June 15, 2026, under the centralized "Buy Canadian" framework (TGWR-256916) operates in the same procurement environment where 70% of contracts awarded between December 2025 and June 2026 under the $5 million threshold went to foreign-owned subsidiaries qualified via "substantial transformation" rules (TGWR-055307). Francis Trudel appears alongside Reza in both dossiers managing these procurement structures.

No cross-dossier contradictions or revolving-door transitions involving Reza are identified in the provided records.
