The System for Electronic Document Analysis and Retrieval (SEDAR) is a mandatory document filing and retrieval system for Canadian public companies. Similar to EDGAR, SEDAR is operated by the Canadian Securities Administrators, a coordinating body comprising the 13 Canadian provincial and territorial securities commissions.

Through SEDAR registered filing agents, public companies file documents such as prospectuses, financial statements and material change reports with the regulatory authorities, and these documents are accessible by the public to further the goal of transparency and full disclosure. Documents filed with regulators prior to the implementation of SEDAR in 1997 are available from the individual provincial or territorial securities commissions.
