Searching SEDAR

SEDAR (the System for Electronic Document Analysis and Retrieval) is the system used for electronically filing most securities related information with the Canadian securities regulatory authorities.  Many Canadian mining companies are publicly traded (for example, on the Toronto Stock Exchange) and are required to file securities related information.  The documents contained in SEDAR include technical reports and other valuable sources of information on mines and mining companies.

1. Go to

2. Click on “Search Database” from the menu at the top of the page.

3. Click on “Search for Company Documents” (not Investment Fund)

4. Search for NI 43-101 (Standards of Disclosure for Mineral Projects)

  • You can search for NI 43-101 documents filed for a particular company, if you know the name,  OR
  • You can search for NI 43-101 Technical Reports (under “Document Types”) and sort it by company name or date of filing.

Please note: 

  • Once you get to the list of results and try to access a document, you will be asked to fill in a code verification, which is case sensitive
  • If a company is not publically traded, it does not show up in SEDAR. For example, Syncrude is a joint venture, and therefore, not traded directly. Instead, you’ll need to search for its parent companies to find documents related to its projects.
