Keep Bank of Canada rate proof with a Canadian record

Who publishes this rate?

The institution publishes the reference rate. FXProof packages the selected source data and verification details into a signed proof.

FXProof is not affiliated with or endorsed by Bank of Canada.

Where does Bank of Canada proof fit in a tax or expense file?

Choose the supported Bank of Canada dataset and the date used in the CAD record. FXProof makes the signed proof PDF available when that dataset-and-date bundle is ready.

Use the Bank of Canada page when the file already names Bank of Canada as the source and needs a consistent evidence package beside the tax, expense, accounting, close, or review record.

Who issues the Bank of Canada rate proof document?

The Bank of Canada remains the publisher of the underlying reference-rate data. The signed document is issued by FXProof, not by the Bank of Canada, and no affiliation or endorsement is implied.

  • Bank of Canada source attribution.
  • Source date or reference date used for the rate.
  • Rate context for the selected dataset and date.
  • FXProof document id, payload hash, digital signature, and verification information.

Can I use a Bank of Canada webpage as my supporting document?

The webpage may be useful source context. The signed FXProof PDF gives the file a consistent record of the selected date and rate context, plus a digital signature and details for public verification.

Keep that PDF with the tax, expense, accounting, close, or review record. The person or organization receiving the file decides whether the evidence meets its requirements.

Questions

Are past Bank of Canada dates always available?

No. Availability depends on the supported dataset, selected date, and readiness of that proof bundle.

Is this PDF issued by the Bank of Canada?

No. FXProof issues and signs the document. The PDF attributes the underlying rate data to the Bank of Canada without claiming affiliation or endorsement.

Should I attach the proof to the CAD calculation?

Yes. Keep the signed PDF with the calculation, close file, tax record, or other business record that used the rate.

How does a reviewer verify the document?

The reviewer can inspect the source and rate context, validate the PDF signature, and use the document id and payload hash on the public FXProof check page.

Keep the proof with the file that used the rate

Inspect a static sample first, then use an account when you need a proof bundle for a concrete dataset and date.
