Building Tariffed

Tyler Gallant · September 2026

I built Tariffed to trace ownership behind Canadian government contracts. AI assists research and development; Node.js processes disclosures into searchable pages and CSVs.

  • 572 contract name groups · 75.42% of processed value
  • 2,026 grant name groups · 65.55% of processed value

Coverage includes partial entries and aliases. Values span the saved files’ history; they are not annual spending or cash paid.

A source check led me to downgrade 11 incomplete ownership entries. The evidence preserves the sources, calculations and corrections.
