Why Canada Post Overcharges Go Unnoticed

Canada Post processes millions of parcels for Canadian businesses every day. With complex pricing tiers, fuel surcharges, and dimensional weight calculations, billing errors are inevitable — and they almost always favour the carrier.

Unlike UPS and FedEx, there are virtually no third-party services that audit Canada Post invoices. This means Canadian businesses using Canada Post have been leaving money on the table with zero recourse — until now.

ShipSherlock is purpose-built for Canada Post's billing system, service guarantees, and claims process. We understand Canadian postal codes, rural surcharge zones, and the specific rules that apply to parcels moving within and across Canadian provinces.

Common Canada Post Billing Errors

Service Guarantee Failures

Canada Post's On-Time Delivery Guarantee applies to Priority and Xpresspost. We track every guaranteed shipment.

Weight Discrepancies

Incorrect actual or dimensional weight applied to your parcels, resulting in higher charges than warranted.

Incorrect Zone Pricing

Parcels charged at the wrong distance zone based on origin and destination postal codes.

Fuel Surcharge Errors

Fuel surcharges applied at incorrect rates or to services that should be exempt.

Built in Canada. Built for Canada Post.

US-based shipping audit companies like Sifted, Share a Refund, and 71lbs don't support Canada Post. ShipSherlock is the only automated audit service that understands Canada Post's unique billing structure, service guarantees, and claims process.

Canada Post Refund FAQs

Does Canada Post have a service guarantee?

Yes. Canada Post's On-Time Delivery Guarantee covers Priority and Xpresspost services. If your parcel is delivered late, you can claim a full refund of postage. ShipSherlock automates this claim process for every eligible shipment.

Why don't other audit services support Canada Post?

Most shipping audit companies are US-based and built around UPS/FedEx APIs. Canada Post uses a different integration model that requires specialized Canadian expertise. ShipSherlock was built from the ground up to handle Canada Post's systems.
