CSA Staff Notice 13-315 (Revised): Securities Regulatory Authority Closed Dates 2026

CSA Staff Notice 13-315 (Revised)
Securities Regulatory Authority Closed Dates 2026 December 4, 2025 We have a review system for prospectuses (including long form, short form and mutual fund prospectuses), prospectus amendments, pre-filings, and waiver applications. It is described in Policy Statement 11-202 respecting Process for Prospectus Reviews in Multiple Jurisdictions (Policy Statement 11-202). Under Policy Statement 11-202, a filer that receives a receipt from the principal regulator will be deemed to have a receipt in each passport jurisdiction where the prospectus was filed. However, the principal regulator’s receipt will only evidence that the Ontario Securities Commission (OSC) has issued a receipt if the OSC is open on the date of the principal regulator’s receipt and has indicated that it is “clear for final”. If the OSC is not open on the date of the principal regulator’s receipt, the principal regulator will issue a second receipt that evidences that the OSC has issued a receipt on the next day that the OSC is open. SEDAR+ is available around the clock on weekdays, including Canadian holidays. Occasionally, between 11:00 p.m. Eastern Time (ET) and 7:00 a.m. ET, system maintenance may be conducted. System maintenance is routinely conducted at various periods on weekends. SEDAR+ operates on ET, so a filing made between 00:00 ET and 23:59 ET will be considered filed on that day. When your prospectus-related filing deadline falls on a weekend or statutory holiday (closed date) for your principal regulator, the deadline moves to the next business day. The following is a list of the closed dates of the securities regulatory authorities for 2026 and January 2027. Bracketed information indicates those jurisdictions that are closed on the particular date. Issuers should note these dates in structuring their affairs.
