How to send a letter or postcard

Envelopes are best for flat, flexible items such as letters, cards, checks, forms, and other paper goods. Choose a sturdy paper envelope that keeps the contents flat and protected.

Standard letter envelopes should be rectangular. If your contents are rigid, unusually thick, square, or cannot bend, they may need package pricing instead of regular letter postage.

Postcards are ideal for short messages that do not need an envelope. Make sure your card leaves enough room for the message, delivery address, and postage.

Write your return address in the upper-left corner of the envelope. This allows the item to be returned if it cannot be delivered.

Put the delivery address clearly in the center. Include the recipient name, street address, city, region, and postal code. For postcards, use the address area printed on the card.

Place the stamp or postage label in the upper-right corner. Heavier, larger, or unusually shaped items may cost more than a standard letter or postcard.

Add tracking, delivery confirmation, insurance, or another extra service when the contents need additional visibility or protection.

Leave it in your mailbox for pickup, place it in an approved collection box, or hand it to the team at an OntracParcel location.

For time-sensitive or valuable mail, ask for a tracked service and keep your receipt until delivery is confirmed.
