U.S. Postal Service Suspends Mail to Canada – What’s Changing?

In early 2025, the U.S. Postal Service (USPS) announced a suspension on accepting new mail destined for Canada. This decision follows increased compliance issues, customs delays, and rising cross-border logistics costs. While the move impacts international senders, understanding its causes and effects helps manage expectations and plan better deliveries.

The New Policy on Mail to Canada

Starting February 2025, USPS no longer processes standard letters and packages sent directly from the U.S. to Canada at postal counterload facilities. This suspension applies primarily to domestic mailers using traditional postal services without customs pre-clearance. The agency cited rising clearance complications and inconsistent international tracking standards as key drivers.

While letters and small packages are currently halted, USPS maintains it continues to deliver essential mail through alternative channels, including secure digital tracking options and partner logistics networks. Customers are advised to use pre-cleared international shipping services to avoid delays.

Why Was the Suspension Implemented?

The suspension reflects growing complexities in cross-border mail handling. Recent data shows a 37% rise in customs delays at the U.S.-Canada border since 2023, partly due to stricter documentation requirements and increased scrutiny. Additionally, USPS reported inconsistent integration between Canadian customs systems and USPS tracking platforms, which disrupts real-time updates and leads to lost or delayed shipments.

Experts note that the policy aligns with broader modernization efforts aimed at improving reliability and security in international mailflows. While frustrating for individual senders and small businesses, it underscores USPS’s focus on system integrity over outdated processes.

What This Means for Senders and Receivers

For individuals and businesses relying on mail to Canada, this suspension means longer delivery times and unpredictable status updates. Tracking numbers may show ‘pending’ or ‘unprocessed’ status until pre-clearance is confirmed. Recipients may face delayed receipt of important documents, gifts, or packages requiring timely handoff.

To adapt, USPS recommends:

• Using paid international express services with customs brokerage.
  
• Ensuring all required forms—such as commercial invoices or customs declarations—are completed accurately before dispatch.
  
• Opting for electronic tracking and notifications to monitor shipments closely.

While USPS continues to evaluate long-term solutions, adopting proactive shipping habits ensures smoother cross-border mailflows. Staying informed through official USPS updates helps minimize disruptions.
