statutory holidays in September 2045
No Canadian federal holidays fall on a weekday in September 2045, so banks and Canada financial markets keep their regular schedule for the entire month.
Canada September deadlines
September 15 is the corporate Q3 instalment deadline. Provinces with March 31 fiscal year-ends are now in Q3. Labour Day on the first Monday closes federal offices and the TSX. The federal fiscal year continues but provincial cycles vary, which complicates joint federal-provincial program reporting in Q3.

Canada reporting cycles and business-day rules
Canadian business-day cycles align with the Bank of Canada Lynx high-value clearing window (08:30 to 18:00 Eastern) and Payments Canada AFT files settling next-business-day. CRA monthly remittance schedules vary by employer size: accelerated remitters file three-business-day windows after each pay period, regular remitters file by the 15th of the following month. Canada Day, Labour Day, and Remembrance Day close federal offices but provincial observance varies, so multi-province contracts often default to the federal-only set this calculator implements.
