Because November 15, 2026 falls on a Sunday, the CRA's weekend rule means regular remitters' October Payroll deductions are on time if the CRA receives them on Monday, November 16.

The answer lies in a standing CRA rule rather than a one-off concession. Regular payroll remitters must send source deductions by the 15th day of the month after the deductions were made, so October's deductions are due on November 15. In 2026, that date is a Sunday. Under the CRA's payroll due-date rules, when a due date falls on a Saturday, Sunday or public holiday, a Remittance is considered on time if it is received on the next Business day. That makes Monday, November 16, 2026 the practical deadline.

The key word is "received". The rule turns on when the CRA receives the payment, not on when an employer starts it, which matters for methods that take time to arrive.

The same rule shows up across the CRA calendar

Several CRA dates in the coming months move for the same reason:

  • GST/HST returns and payments for September (monthly filers) and July to September (quarterly filers) are due one month after the period ends. October 31, 2026 is a Saturday, so the CRA's business deadlines list Monday, November 2, 2026.
  • Ontario Trillium Benefit and advanced Canada workers benefit payments due on October 10 and 11 are being paid on Friday, October 9, 2026, because those dates fall on a weekend. For benefit payments, the shift runs the other way, to the business day before.
  • T4 and T4A slips for 2026 are due on the last day of February. February 28, 2027 is a Sunday, so the date becomes Monday, March 1, 2027.
  • GST/HST filers for the October to December quarter face a January 31, 2027 date that is a Sunday, moving it to Monday, February 1, 2027.

A checklist for the November 15 remittance

  • Confirm the schedule. Regular remitters pay by the 15th of the following month. Quarterly remitters are not due in November; their next date is Friday, January 15, 2027. Threshold 1 accelerated remitters, with an average monthly Withholding amount (AMWA) of $25,000 to $99,999.99, have a separate date on Wednesday, November 25, 2026.
  • Plan for arrival, not dispatch. With drop boxes at 45 CRA locations permanently closed since May 29, 2026, the CRA lists Options such as online services in a CRA account, online or mobile banking, pre-authorized debit, My Payment and third-party providers (fees may apply).
  • Know the penalty tiers. The CRA's late-remittance penalty is 3% for one to three days late, 5% for four to five days, 7% for six to seven days, and 10% for more than seven days or if nothing is remitted.
  • Factor in interest. From October 1 to December 31, 2026, the prescribed rate on overdue taxes, CPP contributions and EI premiums is 7%.

Illustration: on a $10,000 remittance, a 3% penalty would be $300 and a 10% penalty $1,000. This example is for illustration only and is not a CRA calculation.

The bottom line

The Monday grace on November 16, 2026 comes from the CRA's general rule for weekend and holiday due dates. It gives regular remitters one extra day only because the 15th lands on a Sunday this month; December's remittance, due on Tuesday, December 15, gets no such shift. Employers may wish to check how long their chosen payment method takes to reach the CRA.
