An AOG part landing at Montréal-Trudeau (YUL), Toronto Pearson or Vancouver clears on the same CBSA rules as any commercial import. There is no separate AOG document list. This page lists them in the order a broker needs them, and separates them from the release certificate the AMO needs.
TL;DR. Customs side: commercial invoice meeting D1-4-1, the air waybill (its number feeds the cargo control number), a release request, then CARM accounting. Airworthiness side: EASA Form 1, FAA 8130-3 or TCCA Form One, accepted under Transport Canada rules. A part going back after repair abroad can qualify for GST/HST remission under D8-3-8 if you can show it left Canada. Doana extracts EASA Form 1 box by box. It does not file with CBSA.
Which documents does the broker need?
| Document | What it carries | Reference |
|---|---|---|
| Commercial invoice | Seller, buyer, description, quantity, value, origin | D1-4-1 |
| AWB / HAWB | Carrier, pieces, weight; the basis of the cargo control number | D17-1-10 |
| Release request | Goods released before final accounting, with security posted | D17-1-4 |
| CARM accounting (CAD) | Classification, value, duties and taxes | CARM, system of record since 21 October 2024 |
| Proof of Canadian export | For a part returning after repair abroad | D8-3-8 |
D17-1-10 uses mode of transport code 1 for air and makes the invoice or PO number mandatory. It also has a warehouse time-limit code for spare parts of aircraft, which is not a tariff classification. More on the accounting side: CARM for aviation importers.
Is an aircraft part duty-free in Canada?
Often, but check the tariff item. The Customs Tariff lists parts of aircraft under heading 88.07 (propellers and rotors, undercarriages, other parts), and the 2024 schedule shows those items at a free MFN rate (Chapter 88). Many parts fitted to an aircraft classify elsewhere: engines, instruments, tyres, fasteners. A free duty rate does not remove GST.
What if the part was repaired abroad?
The Repair Abroad remission order, explained in D8-3-8, remits the GST/HST on Canadian civil aircraft, engines, flight simulators and their parts returned after repair abroad. Tax is still due on the value of parts used in the repair. You must show at release that the part left Canada and is not a new importation, so keep the export record with the repair station's paperwork.
Where does the release certificate fit?
The Form 1, 8130-3 or TCCA Form One is for the AMO that will install the part, not for CBSA. It still travels with the shipment, and the broker should compare its part number, serial and description with the invoice before filing. A tag that names a different dash number from the invoice is a question CBSA may also ask.
Transport Canada and EASA mutually accept EASA Form 1 and TCCA Form One for components under the MAG (TC MAG). Detail: TCCA Form One and the EASA MAG. For a used US part, see Dual release on FAA 8130-3.
What can a broker automate?
The reading. Doana extracts EASA Form 1 boxes 1 to 14 with a confidence score and page on each value. TCCA Form One and 8130-3 are recognised as other documents (documentType: unknown) and not extracted box by box. The web app reads the certificate type and part numbers from those tags, and a custom pipeline can extract them field by field along with the invoice and AWB. Doana does not submit a CARM declaration. See CARM customs automation and the Form 1 extraction page.
Next
Send the broker the invoice and AWB first; they start the clearance. Send the release certificate with them so the part number can be checked once. If the part is returning from repair, add the export record.
