Important changes to filing regulatory documents

March 17, 2020

All stakeholders should continue to file regulatory documents using the CER’s e-filing service. The CER will postpone the requirement to file a hard copy within three business days until further notice. You should still prepare your hard copies, with the signed receipt, to be filed with the CER at a later date.  We have fewer staff working in our offices, so please do not mail or fax documents. If you have material that cannot be filed electronically, you can email a .pdf document (10 MB or less) to Please include a cover letter to assist CER staff with the internal handling of your file. More information about the CER’s response to the COVID-19 pandemic is available in our March 16 update.
