From that picture it might fit through the Canada Post slot. Sometimes items might be slightly over or the bubble wrap inside might make it hard to push through. Or an item I am sending barely fits through so I just stamp it and put in a red mailbox.
I've had items fit through but it's tight and I end up having arguments with Canada Post employees.
They like to flip the ruler upside down and try to use gravity to make the envelope fit. Then they say it doesn't fit sir. I'm like just push the envelope through. Then they say we don't push envelopes through here sir lol. So I just stamp and put in a red mailbox.
I've never had an item come back that I stamped and put in a red mailbox.
