You can deposit domestic Registered Mail™ items at a post office or processing facility.
You must deposit all Registered Mail at an authorized post office, or give it to a rural mail carrier. These items can’t be dropped into a street mailbox or mail receptacle. We’ll give you proof of mailing at the time of mailing.
Please note: Only Prepaid Registered Mail (PRM) envelopes may be deposited into a street letter box. PRMs are only available to commercial customers. We consider the detachable tracking number as your proof of mailing for PRM envelopes.
We consider items you deposit after the Canada Post approved postal facility cut-off time as deposited on the next business day. See Machineable Mail depositing information for the list of facility cut-off times.
