System for Electronic Document Analysis and Retrieval
（重定向自SEDAR）
The System for Electronic Document Analysis and Retrieval (SEDAR) is a mandatory document filing and retrieval system for Canadian public companies. It is similar to EDGAR, the filing system operated by the Securities and Exchange Commission for United States public companies. SEDAR is administered by the Canadian Securities Administrators, a coordinating body comprising the 13 Canadian provincial and territorial securities commissions, and operated on their behalf since 2014 by the Alberta Securities Commission.
