No, in most cases. In the United States, USPS does not deliver regular mail on federal holidays, and in Canada, Canada Post does not deliver on statutory holidays. A few exceptions exist, such as some package services and private couriers, which often run reduced holiday schedules. Plan around the holiday and mail early.
In the United States, the postal service observes the federal holiday calendar: New Year's Day, Martin Luther King Jr. Day, Presidents Day, Memorial Day, Juneteenth, Independence Day, Labor Day, Columbus Day, Veterans Day, Thanksgiving Day, and Christmas Day. On those days, post offices close and letter carriers do not run their routes. Mail already in the system waits at a processing plant or a local facility until the next business day.
Canada works differently because holidays are set partly by the federal government and partly by each province. Canada Post does not deliver on national statutory holidays such as New Year's Day, Good Friday, Canada Day, Labour Day, and Christmas Day. Some provinces add their own holidays, such as Family Day or the August civic holiday, and delivery in those provinces may stop too, even while the rest of the country keeps moving. A letter crossing from one province to another can therefore hit a holiday stop in the middle of its trip.
Not everything stops. In the United States, USPS Priority Mail Express runs every day of the year in many areas, including most federal holidays, because it is sold as an overnight service. Private couriers set their own calendars: some deliver on holidays with reduced staff, others close entirely, and holiday surcharges are common. In Canada, some courier services run on statutory holidays, but Canada Post's own letter and parcel delivery does not.
Collection also pauses. Street letter boxes are not emptied on a holiday, and post office counters are closed, so a letter dropped in a box on Thanksgiving morning in the US will usually sit there until the next collection day. The same applies to a letter mailed on Christmas Day in Canada. If you are counting days to a deadline, the holiday itself does not count as a delivery day.
| Situation | United States | Canada |
|---|---|---|
| Regular letter delivery | None on federal holidays | None on statutory holidays |
| Post office counters | Closed | Closed |
| Express or courier delivery | Express often runs; couriers vary | Couriers vary; Canada Post does not deliver |
| Holiday calendar source | Federal holidays, same nationwide | Federal plus provincial holidays |
| Mail in transit | Held until next business day | Held until next business day |
Yes, by at least a day. A letter mailed the day before a holiday may arrive at a processing plant that evening and then wait, because the next leg of its trip is scheduled for a business day. A holiday that falls on a Friday or a Monday stretches into a three-day gap, which is why a letter mailed on a Wednesday before Thanksgiving week can take noticeably longer than the same letter mailed in an ordinary week. Long weekends are the classic cause of "my letter is late" complaints that are really just calendar gaps.
One detail people miss: a holiday in the destination country matters, not just the sender's. A letter mailed from Toronto to Chicago on Canada Day will cross into a US system that is working normally, but a letter mailed from Chicago to Toronto on July 4 will sit at the border or in a Canadian facility while Canada Post is closed for its own holidays, and vice versa. Cross-border mail has to clear two holiday calendars.
Mail at least two business days before a holiday if the letter matters, and more if a long weekend is involved. If a deadline falls on or just after a holiday, treat the last business day before the holiday as the real deadline. For time-sensitive letters, registered or certified service helps you prove when the letter entered the system, but it does not make the letter move on a holiday: tracking and proof of delivery pause along with everything else.
With LetterAgent, you mail a letter by asking your AI assistant, and it is printed and mailed as a standard letter with first-class postage or the fastest available non-express service.
