Data Sources & Attribution

TenderScan aggregates public procurement notices from Canadian government portals and open-data platforms. Tender information on this site is reproduced from the sources below and has been modified by TenderScan: we classify notices by industry, extract location fields, filter listings, match them against user keywords, deduplicate notices that appear on multiple source portals, copy buyer names onto matching tenders from other sources (same title, closing date within 7 days), and retain records after the original notice has closed.

TenderScan is an independent service. It is not affiliated with, sponsored by, or endorsed by any government or data provider listed below.

About TenderScanBot

TenderScanBot is the automated reader TenderScan uses for the municipal tender pages listed above. It identifies itself as “TenderScanBot/1.0 (+https://tenderscan.ca/data-sources)”, follows each site's robots.txt and crawl delay, visits each tender page at most twice on weekdays, and reads only the public tender listing. It does not download tender documents, sign in, or fill in registration forms.

If you run one of these websites and would like us to change how we read it or to stop, email support@tenderscan.ca and we will act on it the same day.
