About Canadian Disclosure
An independent, non-partisan public reference platform dedicated to transparency, fiscal accountability, and accessible analysis of Government of Canada proactive disclosure records.
Our Mission
Under Part 2 of the Access to Information Act, federal institutions are legally mandated to publish quarterly disclosures of contracts over $10,000, grants over $25,000, travel, hospitality, and position reclassifications. However, the raw files released on open.canada.ca suffer from widespread fragmentation: vendor names are spelled in dozens of ways, amendment records overwrite historical baselines, and multi-department comparisons require extensive manual data wrangling.
Canadian Disclosure solves this problem by building an automated, open-source data processing pipeline that normalizes supplier names, computes market concentration indices, tracks amendment growth, and indexes records for instant search.
Data Principles
- Strict Factuality: Every number presented on this site is derived mathematically from official open.canada.ca releases. No speculative estimates or synthetic data are generated.
- Clear Procurement Distinction: We always emphasize that contract disclosures reflect total commitment values (original awards plus amendments), not actual payments made.
- Open Access: Reconciled datasets are made available for free bulk download in CSV and JSON formats under open licenses.
Technical Architecture
The site is engineered for maximum performance, minimal carbon footprint, and complete resilience:
- Site Engine: Astro 5 with pure static rendering (SSG) and Tailwind CSS v4.
- Search: Client-side indexing powered by Pagefind for instant, privacy-respecting search across thousands of entities without server queries.
- Data Pipeline: Python 3 ETL pipeline performing automated CKAN schema validation, Business Number Luhn checks, and CPI inflation adjustments.
