looks like it was a mutual thing on money orders, for whatever reason, to me, I could be wrong.
As of August 30, 2019, The Postal Service® no longer sells international postal money orders destined for Canada and no longer cashes international postal money orders issued by Canada Post. Also, as of August 30, 2019, Canada Post no longer sells international postal money orders destined for the U.S. and no longer cashes international postal money orders issued by The Postal Service.
Next Steps
- If you have a USPS® issued international postal money order destined for Canada, you can redeem it at a U.S. Post Office™ facility at face value.
- If you received and have not yet cashed a Canada Post issued money order, it is advised that you return the money order to the sender.
