There's an 8pm cutoff for collecting Priority and Express Mail needing to get to an airplane at the airport across the street. Then it sits over there for hours being processed before actually getting onto an airplane. There is no closer drop-off at the dock at the airport. The Crown counter is open later, but all they can do is stamp your receipt or postmark your item as of that date. If delivery time at the destination is of the essence, then get there before 7pm because you might get stuck in a long line at the counter or at the self service kiosk waiting behind a bunch of people who are all thumbs with the freaking unintuitive touchscreen system. Hint for using the kiosk touchscreen: use your smartphone touchpad pen and touch the center of the button. The thick protective glass makes your fingertip go off center and enter incorrect info too easily. The screen is too low and is not tilted for optimal viewing by standing adults. Don't waste any time trying to call for help.
People answering with "contact the Post Office" are missing the point of the internet. You can't call this post office and reach a human!
Usually 11pm if already postaged
